Abstract:

Boiler Feed Water Pumps (BFWP) are considered a critical part of boilers in power plant operations. The performance of the pump in a system is estimated by one of these quantifiers in pump performance (power, efficiency, head, and flow). The design and balance of the drum in the boiler feed pump are critical for the smooth flow and optimum efficiency of the pump. The wearing tolerance limits of the drum are correlated with the type of pump and the characteristics of the system in which it is installed. A study was conducted to evaluate the drum design at Saudi Aramco Jazan Integrated Gasification Combined Cycle (IGCC) Power Block Project. The study provided a mechanism for improvement in the design issues associated with the internal clearance of balance drums related to the BFWPs. Furthermore, gradual design improvements were also implemented. Successful performance testing of Boiler Feed Water Pumps (BFWPs) fitted with upgraded balance drums was also performed. This study provides a better understanding of drum design and techniques to improve the balance of the drum.

Abstract:

Modernization of automatic control systems of electrical devices plays an important role in terms of energy efficiency and energy saving in the operation of thermal power plants. The development of an educational laboratory stand, which simulates the operation of a direct-flow steam boiler of a coil type as part of a transportable boiler plant, allowed the introduction of an automatic control system for a feed pump with the help of the introduction of a controller, a frequency drive and control of the device through the SCADA program. Using experimental data as a result of the work of the educational laboratory stand, the idea of creating an automated control system for a group of feed pumps for direct-flow steam boilers of the coil type, which are operated as part of a transport boiler plant at an oilfield site, is proposed. This installation and boiler unit are taken as basic models when designing a training laboratory stand. The purpose of the work is to create an automation scheme for a group of pumps of a transportable boiler plant, using experimental data from an educational laboratory stand, as well as taking into account the theoretical and practical component for the use of automation of all or part of a group of feed pumps from the point of view of energy efficiency and energy saving. Materials and methods contain information on the creation and adaptation of a mathematical model to describe the operation of pumps, taking into account hydraulic resistances that arise due to boiler coils – wound pipes of complex shape in the form of a coaxial cylinder. The results of the work are reflected in the form of an algorithmic block diagram of the pump unit and a schematic diagram of the automation of a group of pumps of a boiler plant. In the course of the work, a list of equipment for upgrading the control system of the feed pump unit was proposed. In conclusion, the prospects for further development in this area are considered, the advantages of dividing pumps into subgroups are given, such as the main – regulated and auxiliary – unregulated, as well as positive aspects in the use of frequency control for the main pumps as part of the operated boiler plant.

Abstract:

This article discusses the performance problems associated with process water pumps. It highlights that at a boiler steam load in the 25% to 40% range, an automatic recirculation (ARC) valve is simply not accurate enough to detect a minimum pressure differential change of possibly 1–2 psig when the boiler drum level control valve closes for short-duration process demand changes. Converting the ARC valve to an electronic controller does not work reliably either. The amperage change is difficult to discern at low feedwater flow rates. Failure of the valve to open is a recipe for pump cavitation and becoming “steam bound.” If the boiler trips on “low water,” plant production can be affected immediately. For larger boilers with high-capacity, high-horsepower feed pumps, the ARC valve often becomes an energy conservation (cost) issue.

Abstract:

This paper investigates the integration of heat pumps for heating boiler feedwater and evaluates the impacts of feedwater temperature and condensate recovery rates on fuel consumption, energy efficiency, and CO2 emissions. The results show that using heat pumps significantly reduces boiler fuel consumption, especially when the feedwater temperature increases and the condensate recovery rate is high. The COP (Coefficient of Performance) of the heat pump gradually decreases as the water temperature rises; however, heating the water at lower temperatures yields better economic and energy efficiency. Economically, heat pumps provide substantial benefits, with maximum cost savings achieved at a water temperature of 75°C. Additionally, integrating heat pumps reduces CO2 emissions, particularly in boilers without condensate recovery, with the highest emission reduction reaching 17.8 kgCO2 per ton of steam. These findings demonstrate that using heat pumps is not only energy-efficient and cost-effective but also contributes to environmental protection by reducing greenhouse gas emissions.

Abstract:

Abstract A case study was carried out to investigate the effectiveness of condition monitoring techniques in the early failure detection of pumps in a thermal power plant. Various condition monitoring techniques used in this case study involved vibration analysis, motor current signature analysis, noise monitoring and wear debris analysis. These techniques were applied on the three pumps, namely boiler feed water pump, auxiliary cooling water pump and condensate extraction pump, which have to work continuously for the operation of the thermal power plant. Vibration analysis of the auxiliary cooling water pump showed that there is a rising trend in the acceleration values at its driving and non-driving end indicating the deterioration of bearings. Motor current index range of all the pumps was found to be within acceptable limits. Wear debris analysis of lubricant in the hydraulic coupling of boiler feed water pump indicated the presence of sand, dirt and low alloy steel sliding wear particles in it. Condition monitoring techniques have been proved to be an effective technique in early failure detection of pumps.

Abstract:

The goal of this work is to automate the Sapele Power Plant Boiler Feed Pumps (BFPs) using CODESYS software to simulate BFP controlled by a proposed PLC system that was manually controlled. The boiler pressure, level, feed stream flow, and primary heat transport (PHT) pressure BFP were restored to their optimal levels within a few seconds after trip. This was possible for the standby program used for automation within 14 seconds when compared to the manual process that was in place. During the simulation, the BFP goes into standby mode after 14 seconds. The results obtained under automated condition shows the boiler pressure rises to 40.3 kg/cm-1s-2 and remained stable for 147 seconds as against 55.9 kg/cm-1s-2 in 25 seconds under unautomated conditions. The flow rate of the feed water shows a decrease of -0.172 m at 50 seconds. The boiler pressure rose further to 44 kg/cm-1s-2 at 175 seconds, which corresponds to a specific gravity value of 59.5 kg/cm3 at the same time. At 146 seconds, the feed water hits the trip setting of -2.85m owed to low specific gravity (SG) level when compared to the unautomated condition. Thus, a further increase reached fluctuation level of -10m at 200 seconds. The PHT was 88.5 kg/cm-1s-2 at 146 seconds contrary to the expected pressure of 105.6 kg/cm-1s-2 for unautomated state. This change after 146 seconds results from generator trip. The pressure increases to 90.2 kg/cm3 at approximately 148 seconds and subsequently decreases to 48 kg/cm3 consequently opening of the condenser steam discharge valve (CSDVs) and atmospheric steam discharge valve (ASDVs) during the simulation state.

Abstract:

A transportable boiler plant is used to provide consumers with steam of high energy characteristics, while saving costs for the construction of stationary boiler houses. A transportable boiler plant can be placed in the conditions of the Far North on an oilfield site. It is therefore necessary to organize reliable and safe operation of the boiler house, consisting of a steam direct-flow boiler of the coil type, a feed pump, a feed water tank and other auxiliary elements of the thermal circuit. One of the important elements in the thermal circuit is the feed water tank, in which water accumulates after chemical purification. It is where the water is also heated, increasing the efficiency of the boiler. Methods for calculating the diameters of main steam pipelines and feed water pipelines are described. The theoretical foundations of the operation of the feed water tank, its use in thermal power plants, combined heat and power plants, district industrial and heating boilers using various thermal arrangements of the above-mentioned enterprises are considered. The operation of the feed water tank in the thermal circuit of a steam unit is discussed. A thermal circuit of an industrial boiler house has been designed to generate saturated steam for consumers using direct-flow steam boilers of the coil type. The diameters of the inlet and outlet pipelines of the storage tank are calculated. The effective thickness of thermal insulation required to minimize heat losses during operation of a transportable boiler plant has been determined. Modeling of the design of the feed water tank and heat losses through its surface is carried out. A 3D model of the designed tank is presented, as well as heat losses through the surface of the tank walls when using a thermal insulation material. The importance of using thermal insulation of various tanks for storing feed water, petroleum products, hydrocarbons and other various media is noted.

Abstract:

PT. PLN Nusantara Power UP Tenayan is a company operating in the power generation sector and focuses on operating PLTUs Tenayan, Indonesia. One part of the machine that influences the operation of the generator is the boiler feed pump. Lack of optimal boiler feed pump instrumentation often results in failure in operating activities. This research uses the Failure Mode and Effect Analysis (FMEA) method with the research objective of finding out the causes of failures that occur, identifying the type of failure, and determining the RPN value and the impact that occurs. The analysis results, it shows that the Boiler Feed Pump instrumentation components still meet operating standards because the Risk Priority Number (RPN) value is below 200, even though the Speed Sensor has a fairly high RPN value but is still in the reliable category, the result of identifying the type of failure that occurs is that the indicator reading is not actual, the component is not functioning, the highest RPN value for the Boiler Feed Pump component is the Speed Sensor component with an RPN value of 160 and the lowest RPN value is for the pressure indicator component with an RPN value of 30. The most important recommended action for the Speed Sensor component is to carry out maintenance for 1 month very.Keywords – Boiler Feed Pump, FMEA, Keandalan, Pembangkit, RPN.

Abstract:

The first phase of a power plant has two subcritical 300 MW units, and each boiler feed water pump is equipped with two with 50% capacity steam driven feed pumps and one 50% capacity electric start-up feed pump. The two steam pumps are put into operation during normal operation. After the heat supply transformation in the unit of the first phase of this power plant and based on the calculation and analysis of the heat balance of the unit, it is found that there will be insufficient output of the feed pump due to the insufficient steam source after the flow-through transformation, which will affect the water supply of the unit and reduce the energy utilization rate. To avoid this, the steam source of feed pump turbine needs to be selected again. Taking the original steam turbine condition of feed pump and the original steam source of feed pump turbine as the research basis, this paper makes analysis on the steam source transformation, and concludes the scheme of steam source selection and reconstruction based on energy matching. The feasibility of the scheme is tested and verified finally.

Abstract:

For rotordynamic calculations on multistage pumps, one must know–among other things–the hydrodynamic forces generated by a vibrating impeller. In linearized form these forces may be described by stiffness, damping, and mass matrices. Such matrices were measured with the help of a test apparatus using the “rocking arm” principle for an impeller of 0.35 m (13.8 in.) dia at various speeds. It is shown that the hydrodynamic forces generated by the vibrating impeller can be described reasonably well by the standard rotordynamic stiffness, damping, and mass matrices, except for the direct damping term which had to be supplemented by a damping term whose magnitude is proportional to displacement rather than velocity. It is further shown how the test results can directly be compared with results from tests using circular orbits.

Abstract:

: Failure Modes, Effects, and Criticality Analysis are widely used to assess the failure modes of a system, along with their causes and effects. Several Multi-Criteria Decision-Making approaches have been developed to overcome the limitations of the traditional FMECA. In these approaches, several multiple criteria are considered to determine the criticality values and assign criticality ranks. In these developed approaches, only one expert can involve in criticality analysis. By incorporating several experts from design, manufacturing, and maintenance domains in the criticality analysis accuracy of the results can be improved. This paper proposes a new integrated Expert Judgment-based Preference Section Index (ExJ-PSI) model that combines MCDM approaches and integrates expert opinions. The proposed model is applied to a boiler system used in the textile industry. The results are compared with those obtained from the conventional FMECA and normalized median method. In the present study, the opinions of seven experts from various domains and organizations are discussed. To normalize the collected data, one scale is developed by considering four expert criteria, such as the experience of the expert, the number of boilers he is handling, the number of employees under his supervision, and the proficiency in the field. The proposed model is more effective and flexible in handling and analyzing data of complex configured systems consisting of many subsystems, components, and failure modes. The analysis reveals that the feed water pump, feed water pump motor, supply water temperature sensor, return water temperature sensor, header, and coal feed motor are some of the most critical components of the boiler system.

Abstract:

Open cycle feed systems featuring a deaerator followed by the boiler feed pumps have been subject to unexpected loss in net positive suction head during transient operation. This has been traced to separation at the deaerator storage tank drain and the formation of a steam/water interface in the downcomer to the pumps. The outflow at separation when the storage tank water is subcooled is generally much greater than the maximum suction flow corresponding to the unit rating, but when the tank water boils, as during transients, it may be very much less. Thus with a high suction flow in the boiling mode, the new interface may descend in the downcomer to result in feed pump cavitation, pressure imbalance, vapor locking, severe vibration, damage to the pump and an inability to maintain forward flow. Model tests have been conducted to establish the criterion for the separation in terms of the critical outflow for specific operating conditions as a function of geometric ratios involving tank-water depth and tank/downcomer dimensions. The data obtained although scattered are in general agreement with the data from actual plant and may be used to assess safe operating parameters.

Abstract:

British domestic design practice is described for boiler feed pump suction systems associated with high level deaerator/feed water tanks in large modern power plant. The objective of thermal–hydraulic design is the provision of adequate pressure to boiler feed water pump suctions under all transient and steady state conditions to ensure continuity of water flow and reliable pump operation. Methods are available for the determination of pressure decay in feed tanks during load transients, but the successful application of mathematical relationships between pressure decay and pressure rise in suction pipework depends on the correct identification of operational circumstances. Progress in recent years has been on the identification of circumstances which produce governing conditions and has taken design practice beyond the stage established by early workers. Developed practice has been successfully applied by the Central Electricity Generating Board and its main plant contractors to forty-nine 500 MW units in coal- and oil-fired stations and to twenty-three 660 MW units in coal, oil and advanced gas-cooled reactor stations, which at 39 680 MW, constitutes the major proportion of plant in England and Wales. Aspects of plant behaviour and operation crucial to successful system design are featured. Recommendations are made for plant layout, pipework routing, tank outlet and pipework sizing, net positive suction head (NPSH) determination etc.

Jurnal ini menjelaskan proses produksi body upper generating drum type CAP.120 T/H. Komponen upper generating drum adalah salah satu komponen pada boiler pipa air yang berfungsi sebagai reservoir campuran air dan uap air, dan juga berfungsi untuk memisahkan uap air dengan air pada proses pembentukan uap superheater. Namun tidak semua boiler pipa air (water tube) yang menggunakan upper generating drum ini. Boiler supercritical beroperasi pada tekanan sangat tinggi di atas tekanan kritis, sehingga tidak dimungkinkan terbentuk gelembung-gelembung uap air, karena itulah boiler supercritical tidak memerlukan upper generating drum untuk memisahkan air dengan uap air. Air feed water yang disupply oleh boiler feed water pump, masuk ke boiler menuju economiser dan selanjutnya masuk ke upper generating drum.

Abstract:

Deaerator merupakan peralatan yang sangat penting pada pembangkit listrik tenaga uap. Deaerator berfungsi untuk menghilangkan gas-gas terlarut yang terkandung dalam air pengisi (feed wate). Level deaerator adalah parameter yang sangat penting untuk dijaga saat proses deaerari (pembuangan gas-gas terlarut). Jika level deaerator terlalu rendah, dapat mengakibatkan rusaknya boiler feed pump dan menngganggu pasokan air ke boiler, namun jika level terlalu tinggi, kandungan gas-gas terlarut seperti karbondioksida (CO2) dan Oksigen (O2) akan tinggi. Pengaturan level deaerator pada PLTU Teluk Balikpapan harus memperhatikan condensate pump discharge pressure. Pengaturan level deaerator dan condensate pump discharge pressure pada PLTU Teluk Balikpapan dilakukan dengan mengatur bukaan deaerator level control valve dan condenser recycle control valve. Penelitian ini akan memodelkan sistem kontrol self-tuning fuzzy PID controller yang disimulasikan menggunakan software MATLA-Simulink. Berdasarkan 3 pengujian yang dilakukan menggunakan 3 karakteristik gangguan yang berbeda, self-tuning fuzzy PID controller memberikan respon yang memuaskan karena berhasil menjaga level deaerator dan condensate pump discharge pressure sesuai dengan batasan operasi kedua parameter tersebut. Dari hasil 3 pengujian yang telah dilakukan, didapatkan nilai error maksimum level sebesar 6,6288 % dan Root Mean Square Error (RMSE) sebesar 20 mm sedangkan untuk error maksimum tekanan sebesaar 21 % dan Root Mean Square Error (RMSE) sebesar 0,035 Mpa.

Abstract:

Economical operation of modern powerful boilers and condenser turbines of hydrorecirculation stations (GRES) is possible only when auxiliary installations (mills, crushers, cranes, conveyors, pumps, fans, etc.) are required for the preparation and transport of solid fuel, air supply to the chambers burning fuel and removing combustion products and ash from them, supplying water to boiler units, maintaining a vacuum in turbine condensers, water supply to the station, and much more. Recently, the specific costs of heat power plants used are 25-30% higher than those of power plants that use modern technologies. One of the priority areas for the development of modern energy in Russia is the technical re-equipment and reconstruction of obsolete operating hydrorecirculation stations with the extension of their service life and the replacement of the main and auxiliary equipment with new ones with improved technical and economic characteristics. The priority in this case is to increase the efficiency of fuel use, energy and resource saving. The article discusses the main causes of uneconomical modes of operation of electric drives during operation in the auxiliary system of JV Raichikhinskaya GRES. To improve the performance and service life of the multistage centrifugal feed water pump PE 270-150-3, the article proposes the use of a frequency-controlled electric drive.

Abstract:

Exergy analysis of power plants that utilize exhaust heat at Cemen plant was carried out to identify the reliability of the generator as a whole system or for each component that could be used as a basis for optimizing the utilization of exhaust heat and optimizing the operation of the generator to make it more efficient with increasing usage life. The exergy flow and efficiency are calculated for each component, and the data is then used to calculate how much exergy is destroyed in each component. Calculations are also carried out on the system at the time of commissioning in order to get how much the exergy efficiency has changed since the system was operational. The components of this plant include an SP boiler, AQC boiler, turbine, condenser, condensate pump, Flasher, boiler feed pump, and economist. AQC boiler is the component with the highest exergy value that is destroyed, which is 4405.34 kW or 32.98% of the total exergy destroyed in the system. The condensate pump is the component that has the smallest destroyed exergy value of 18.94 kW (0.14%). The system efficiency in January 2012 was 62.60% and decreased in December 2019 to 53.04%, where the overall system exergy efficiency decreased by 9.56% within 7 years of operation.

Abstract:

Boiler Feed Pump Turbine (BFPT) merupakan salah satu pompa jenis sentrifugal dengan tipe multistage yang digerakkan oleh turbin kecil. Pompa ini digunakan untuk mensirkulasikan air demineralisasi dari deaerator menuju boiler. Berdasarkan pengecekan vibrasi yang dilakukan oleh bagian Condition Based Maintenance (CBM), telah ditemukan bahwa terjadi over vibrasi pada BFPT dikarenakan adanya indikasi perubahan natural frequency mendekati putaran operasi. Pada penelitian ini dilakukan simulasi Finite Element Analysis dengan software ANSYS Workbench untuk mendapatkan nilai natural frequency pada poros BFPT serta membahas mengenai kemungkinan penyebab terjadinya perubahan natural frequency. Berdasarkan simulasi ANSYS yang telah dilakukan, didapatkan bahwa nilai dari natural frequency dapat berubah karena adanya perubahan defleksi dan menampilkan bahwa setiap modus getar menghasilkan nilai natural frequency yang berbeda juga. Pada simulasi ini didapatkan 6 nilai natural frequency pada poros BFPT yaitu 166,84 Hz, 166,99 Hz, 295,71 Hz, 465,83 Hz, 466,23 Hz, 503,46 Hz. Serta pada penelitian ini didapatkan juga bahwa vibrasi yang terjadi pada BFPT bukan akibat dari perubahan natural frequency, tetapi akibat adanya losseness pada housing bearing pompa.

Abstract:

Centrifugal pumps are commonly used in industrial and domestic sectors to transport fluids by increasing their flow rate to a specific pressure. One type of centrifugal pump, the Boiler Feed Pump (BFP), plays a crucial role in steam power plants. Designed for continuous operation, BFP shafts are prone to wear and failure due to extreme operational conditions. This study employs computer-aided simulation using SolidWorks software to analyze von Mises stress, displacement, strain, and safety factors of BFP shafts with three material variations: AISI 4140, AISI 316, and AISI 304. The results indicate that AISI 4140 material exhibits the highest safety factor of 2.7 and the lowest displacement of 0.453 mm. Fatigue simulation also shows that AISI 4140 has the lowest damage percentage and the highest fatigue life. These findings suggest that AISI 4140 is the optimal material choice to enhance the durability and efficiency of shafts in applications requiring high reliability, such as BFPs in steam power plants.

Abstract:

Boiler feed pump turbine (BFPT) has an important role in the circulating of demin water from deaerator to the separator of steam power plant operations (PLTU) in Cirebon. Flow rate, temperature and pressure were important parameters in boiler feed pump process. Based on the BFPT function, it was necessary to do the analysis interpretation of the performance BFPT. Data needed for evaluation include pressure and temperature on the suction, pressure and temperature on the discharge, and flow capacity. In this study, the data were taken starting in January to December 2014. Data processing was performed using a centrifugal pump calculations, presented in tables and graphs using MS Excel. Analysis of data using qualitative interpretation of quantitative data. BFPT efficiency during operations in 2014 decreased in February - March amounted to 17.91% (BFPT A) and 18.04% (BFPT B). BFPT A highest efficiency obtained in January amounted to 73.76%, the lowest in March amounted to 55.45%. The highest efficiency BFPT B in February amounted to 72.94%, the lowest in March amounted to 54.9%. Change of Performance BFPT occur due to changes load generator power plant that led to the pressure change and flow capacity. Other factors that degrade the performance because BFPT was operated continuously for 24 hours and the age of BFPT sufficient old cause decrease in pump performance.

Abstract:

This paper presents the thermal and economic performance of a 210 MWe coal-fired power plant situated in North India. Analysis is used to predict coal consumption rate, overall thermal efficiency, mass flow rate of steam through boiler, and Net present value (NPV) of plant for given load. Thermodynamic analysis was carried out using mass and energy equations followed by empirical correlations. Predicted mass flow rate of steam, coal consumption rate, and thermal efficiency give fair agreement with plant operating data. The economic analysis includes operational activities such as equipment cost, fuel cost, operations and maintenance cost, revenue, and plant net present value. From economic point of view, the effect of condensate extraction pump redundancy on net present value is observed to be sensitive than boiler feed pump redundancy.

Abstract:

As in all areas relevant to the development and production of pumps the tasks the hydraulic engineer has to deal with have undergone a remarkable change in recent decades: from a more or less unrestricted design of components to design roles dictated by manufacturing techniques. These general trends are accompanied by developments related to changes of the market requirements. This is demonstrated for three particular pump types. The consequences of the demand to save energy—with all the different aspects—are described for the example of heating circulation pumps. The still growing environmental awareness is a challenge for an enlargement of the presently valid operation limits of sealless pumps and for the development of intelligent monitoring systems. It is demonstrated that the developments in the field of boiler feed pumps are closely related to the growing unit sizes. Availability and reliability, and as far as very large pumps are concerned the efficiency, have always been and still are the dominant criteria.

Abstract:

Abstract The change in water flow required at the BFP pump at the Barru Power Plant is only regulated by a valve located on the pressure side, causing excess power consumption and its own power consumption. One effort to save energy usage is to make frequency adjustments that refer to the right pressure and water flow. To determine the effect of frequency adjustments on the expected pump pressure, a simulation of frequency inverter modeling is performed using the SPWM switching method based on the pump affinity law using Matlab application software. The simulation results obtained that by adjusting the frequency range of the inverter from 45.5 Hz to 50 Hz and keeping the pump pressure above the minimum limit of 13.2 MPa, the operating power savings of the BFP motor are obtained from 46 kW to 378 kW.

The thermal power station uses some amount of their generated power to be consumed by its auxiliary power requirements. The auxiliary power consumption in the country is around 8-9%. The auxiliary power consumption can be minimize by increasing the load factor, by operational optimization, applying advanced control techniques and energy efficient measures. By decreasing the auxiliary power extra power will be available at grid. Thus, the aim of the audit is to determine the potential areas for minimizing auxiliary power consumption by operational optimization and energy management policy to improve energy efficiency of auxiliaries. This study will give the basic understanding of energy management approach, energy efficiency and energy saving areas so as to achieve maximum plant efficiency resulting fuel saving. Boiler feed pump is one of the equipment in a power plant with the highest auxiliary consumption.

ABSTRACT The purpose of the project is to assess the major power consumption by auxiliaries and suggesting cost saving alternatives in terms of energy saving. Energy audit of Plant have been conducted for main auxiliaries of thermal power plant like Boiler, Turbine, Condenser vacuum system, performance evaluation of Air pre-heater, MAKE UP water consumption. Various parameters from Control room and Chemical wings has been taken and it was found that the efficiency of boiler is 85.29% which we can improve up to >89% by reducing dry flue gas losses. There is a lot of wastage of MAKE UP water in the plant; we can save this MAKE UP water by making small investment in terms of replacement of valves, gland, seat etc. Heat rate of turbine was calculated, and it was found that it is more than the design heat rate due to low vacuum and process parameters. Vacuum of condenser can be improved by Condenser online Load Tube Cleaning System. We can improve the vacuum and obtain the saving of more than Rs. 200 Lakhs. There is a huge amount of water passing in Boiler Feed Pump recirculation line, after carrying out the various calculated on Boiler Feed Pump, it is observed that the anticipated saving of approximately  Rs. 27 Lakhs per year with an investment of Rs.5.0 Lakhs by replacement of valves. Therefore by adopting some precautions and recommendations we can reduce the power consumption. The total anticipated saving will be more than >3500 Lakhs. per annum with an investment of approx. Rs.2300 lakhs and payback period is 7.5 months.The study conducted clearly shows that the preventive maintenance, overhauling and re-assessment of operating conditions of aging plant imparts a major role in  keeping a power plant an energy efficient utility.

Screw grooved annular seals are used in many heavy duty pumps such as boiler feed pumps. These annular seals have a significant effect on rotordynamic characteristics of the pumps. Studies on the dynamic characteristics of plain and circumferentially grooved annular seals have been published by many researchers. However, published works on screw grooved seals are few, and pump designers have not fully recognized the basic characteristics of screw grooved seals. Extensive experimental studies have been conducted for determining the basic characteristics of screw grooved seals. The leakage characteristics, load capacity, and dynamic characteristics for rotordynamic analysis were determined by using a specially designed test facility and test method. The test results were compared to the results of plain seals [3] and the basic differences were extracted for effective application of screw grooved seals.

Abstract:

Vibration due to mass imbalance in rotating parts such as in pump impellers is an important engineering problem. It is a very important factor to be considered in modern machine design, especially where high speed and reliability are significant considerations. Due to mass imbalance excessive vibration  occurs and may lead to decrease in fluid velocity and pressure which may cause cavitation in the pump. Reducing rotor vibrations generally increases the service life of the rotating machinery. International Standard ISO 1940/1 is a widely accepted reference for selecting rigid rotor balance quality. This paper presents effect of balancing a Boiler Feed Pump (BFP) on two different grades G6.3 and G2.5 as specified by ISO 1940/1 and their effect on the pump performance considering the vibration as the parameter.

Abstract:

A Boiler Feed Pump (BFP) is a very important equipment in Steam Power Plants (PLTU), which functions to pump water from the feedwater tank to the boiler drum. If the BFP experiences a disturbance, the PLTU will experience derating or shutdown. For one year, there were repeated disruptions to BFP, causing the plant to experience an unplanned shutdown (Forced Outage/FO). Analysis of disturbance data was carried out to find the root cause of the problem of repeated disturbances in BFP, using the Root Cause Failure Analysis (RCFA) method. RCFA results show that the cause of repeated interference in BFP is a problem with the Speed Control Actuator which uses an Analog Electric Actuator (Motorized) as a Hydraulic Coupling drive. The main disadvantages of the Analog Electric Actuator system are low response speed, easily changing settings, motor protection often fails and the module often hangs. The solution to this problem is to carry out a retrofit to replace the BFP actuator speed control from an Analog Electric Actuator system to a Digital Electro Pneumatic system.. The retrofit was successfully performed on BFP 1A and proved to be able to operate normally without interruption during the period of operation. After a successful retrofit was performed on BFP 1A, the retrofit was also performed on all other BFPs, namely BFP 2B, 2A, and 1B. Overall, retrofit proved to be able to overcome the weaknesses of the Analog Electric Actuator system and improve the reliability of the power plant. Financially, retrofits eliminate corrective maintenance costs of actuator replacement and eliminate potential plant losses due to lost production opportunities.

Abstract:

Abstract Indonesia’s palm oil industry is considered one of the biggest in the world. Palm Oil Mill Effluent (POME) has the potential for further processing, which can be used as a substitute for boiler fuel (co-firing). Research on converting POME to biogas for boiler fuel (co-firing) in the oil palm plantation Sei Pagar Riau has been carried out. This study aimed to investigate and analyze the biogas production from Palm Oil Mill Effluent at different feed flow rates in Biogas Plant Sei Pagar Riau. Experiments were carried out using the Continuous Stirred-Tank Reactor (CSTR). The reactor capacity was 2000 m3. The reactor was equipped with one unit of vertical agitator and three units of horizontal agitators. POME was distributed from the fat pit unit to the pretreatment unit using the fat pit transfer pump. From the pretreatment unit, then POME proceeds to the reactor using the reactor feed pump started from 2.4 m3/h then gradually increase to 6.3 m3/h as the highest feed flow rate. Biogas was produced in the anaerobic reactor at mesophilic temperature. This study showed that an increase in the POME feed flow rate into the reactor also increases the production of biogas generated in the reactor. The biogas production began to increase every day, with the highest average biogas production of 167 m3/h. The methane concentration was also measured and showed that the highest methane concentration was on day 6, with a value of 70%. And then, the methane concentration trend decreased. However, it was relatively stable in the range of 62.1%-66.7% on day 18 to day 53. Based on this research, it was found that the optimal biogas production of the Biogas Plant in Sei Pagar Riau was generated when the POME feed flow rate was gradually increased and reached the maximum capacity according to its design.
