Full textAbstract:
The use of computational fluid dynamics (CFD) models significantly extends the capabilities for the detailed analysis of the complex heat transfer and gas dynamic processes that occur in the internal gas circuit of a Stirling engine by more accurately predicting the engine’s performance. This accurate data on operational characteristics of the engine can then contribute to more precise calculations of the dimensions of a parabolic concentrator in a dish/Stirling engine installation. In this paper a successful axisymmetric CFD simulation of a solar “V”-type Stirling engine is described for the first time. The standard κ-ε turbulence model, with a moving mesh to reflect the reciprocating motion of the pistons, has been employed for the analysis of the engine’s working process. The gas temperature and pressure distributions and velocity fields in the internal gas circuit of the machine have been obtained and the pressure-volume diagrams have been calculated. Comparison of the numerical results produced from the axisymmetric CFD simulation of the engine’s working process with those computed with the use of second-order mathematical analysis shows that there are considerable differences. In particular, analysis of the data obtained indicates that the gas temperature in the compression space depends on the location in the cylinder for the given moment in the cycle and it may differ substantially from being harmonic in time.

Full textAbstract:
Several cases of the need for continuous utilization of gas turbines for power production and why gas turbines will be relevant in the next 50 years in the Nigerian power sector are presented in this paper. Using 7 criteria; the cost of installation, operation and maintenance costs, levelized cost of electricity, capacity factor, the efficiency of energy conversion, power to size ratio/area coverage and environmental pollution, gas turbine operation was compared with wind and solar energy technologies. Gas turbine for power production appears to be more favourable in 5 out of the 7 criteria including lower installation cost which is a very important factor for poor and developing nations like Nigeria. The quantity of fuel for producing different quantities of power using gas turbines was estimated. Nigeria has huge proven reserves of natural gas which is the fuel for gas turbines. If we go for combined cycle power plants which have low specific fuel consumption (SFC), 50% of the natural gas reserves are enough to produce some 35 GW of electricity for over 50 years. The current rate of natural gas production can produce 27.06 GW of electricity at 0.06kg/s.MW sfc. It was also observed that the current installed power from gas turbines is too low compared to the power demand; hence, further installations are required. Pollution should not be an issue in installing more gas turbine plants because the gas turbine is a clean-burning engine and the present installed capacity is insignificant compared to what is obtainable in some advanced nations. The results in this work will guide gas turbine operators in planning for further installation of gas turbine power plants. The study does not rule out the need to exploit solar photovoltaic system and wind turbines in areas with high sunshine and high wind speeds respectively, for off-grid power production.

Voir résumé étendu en français en fin de thèseIn the actual energetic and economic context, energy polygeneration represents the answer regarding the efficient use of a fuel. This solution would diminish the losses associated to the classical methods of energy production and, as a result, would increase the installations' efficiency. The polygeneration systems (cogeneration/trigeneration of energy), consist of various technologies that offer alternatives to the global problems linked to energy, such as energy scarcity, energy supply security, emissions control from the production of energy, economy and energy conservation, etc.. This doctoral thesis examines two types of polygeneration of energy. The first part focuses on the analysis of a high power trigeneration system based on a gas turbine installation for production of electrical energy, the second part of the thesis is dealing with a system of micro-cogeneration of energy powered by a solar Stirling engine. Given the actuality and interest for the polygeneration field of energy production, there is a constant concern to simulate and optimize the operation of this kind of systems in order to achieve significant performance designed to satisfy the consumers' needs

Full textAbstract:
This work presents a detailed model of performance of Stirling engines which is expected to be of interest for the Concentrated Solar Power community. In effect, gas turbines of different types have been proposed for small and medium scale solar applications based on their reduced (even inexistent) water consumption and modularity. In the medium to large scale, conventional steam turbine based plants demand high investment costs as well as high operation costs (mostly due to water consumption). In the small-scale it is the Stirling engine which is generally consider as the prime mover of choice due to its high efficiency at moderate temperatures. In this context, this paper describes a detailed model of performance of Stirling engines. The model includes frictional and mechanical losses, heat transfer within the engine and other features like auxiliary power consumption and applies to both on-design and off-design operation. The validation of all these capabilities is also presented in the text. Hence, the model is expected to provide a valuable tool for individuals who need to assess the performance of externally heated piston engines.

Full textAbstract:
Distributed generation emerged as a new philosophy for electricity generation in our time, since then, it has been possible to see new concepts of technology following the idea of energy production away from the main producers or in remote areas, mainly in the countryside. Distributed generation technologies include small gas turbine engines, internal combustion reciprocating engines, photovoltaic panels, fuel cells, solar thermal conversion and Stirling engines using fossil and biofuels. Among them, the small gas turbine engine that generates electricity and heat working with fossil or renewable fuels is a promising technology for the near future. The aim of this work is the cycle analysis and preliminary compressor design of a 600kW simple cycle gas turbine engine that has been developed in Brazil. The 600kW engine will be the first prototype of its class in Brazil. A cycle performance calculation for different pressure ratios and turbine inlet temperature was carried out for fixed component efficiencies and losses. A selection of the design point was discussed and compared with the existing commercial engines of the same class. A compressor design point calculation was carried out with a mean line calculation CODE developed in FORTAN language. A CFD simulation was used for flow field analyses and design refinement.

Full textAbstract:
This paper presents how a major U.S. gas transmission and storage company restored gas storage peaking capacity by repowering obsolete gas turbine compressor units. Consumers Power Company’s Ray Field located in Macomb County, Michigan, USA, was developed as a 44 BCF working capacity gas storage field in 1966. Due to the high deliverability, the field is operated as a peaking reservoir, handling rates as high as 500 MMCFD on injection and 1,200 MMCFD on withdrawal. Ten (10) 2,750 horsepower gas turbine driven 4-stage centrifugal compressor units were installed in the mid to late 1960’s at the field. The compression is operated 2, 4 and 8 stage, as needed, to cover storage pressures of 450 to 1800 psig. Each centrifugal compressor is driven by a Pratt Whitney (PW) GG-12 Gas Generator firing into a Cooper-Bessemer (CB) RT-27 Power Turbine. By 1980 parts and maintenance services for the PW GG-12 Gas Generator became very expensive to non-existent. Aircraft use of the GG-12 (JT-12) had been phased out. Consumers Power, with 13 of these turbines on their system, was becoming the only remaining user. In the mid 1980’s four (4) of the Ray Field gas turbine compressor units were replaced with two (2) 6,000 horsepower reciprocating engine compressor units. These replacements maintained the deliverability of the field and provided salvageable engines and other parts to maintain the six (6) remaining turbines. However, by 1993 maintenance parts returned as a major problem as well as unit availability on the 6 remaining turbine units. In 1994 Consumers Power committed to a gas turbine unit repowering program as the preferred choice over unit replacement. Two (2) refurbished Solar Centaur T4500 Gas Turbine drives were purchased and installed to repower 2 of the obsolete turbine units. These installations have been very successful. Existing compressors, foundations, piping, coolers and auxiliary systems were re-used with only minor modification. The complete installed cost for repowering was about 33% of the cost experienced for replacement. Installation was completed within eight (8) months of project commitment. The low emission rates from the Solar SoLoNOx Combustors allowed short lead time (6 months) on air emissions permit. New sound attenuation enclosures met the new local noise ordinance and replaced equipment that had been a source of local complaint. PLC based controls improved reliability and flexibility of operation. The additional horsepower available from the T4500 Turbine (4,300 vs 2,750) allows for increased future capacity. Because of the success of the Ray Turbine Repowering Project, Consumers Power has committed to 2 more refurbished Solar Centaur T4500 Units to repower PW/CB Turbines at the St Clair Compressor Station. Solar is scheduled to delivery these 2 units by year-end 1995 for installation in 1996.

In ASME 1998 International Gas Turbine and Aeroengine Congress and Exhibition. American Society of Mechanical Engineers, 1998. http://dx.doi.org/10.1115/98-gt-529.
Full textAbstract:
The goal of the Ceramic Stationary Gas Turbine (CSGT) Development Program, under the sponsorship of the United States Department of Energy (DOE), Office of Industrial Technologies (OIT), is to improve the performance (fuel efficiency, output power, and exhaust emissions) of stationary gas turbines in cogeneration through the selective replacement of hot section components with ceramic parts. This program, which is headed by Solar Turbines Incorporated and supported by various suppliers, and national research institutes, includes detailed engine and component design, procurement, and field testing. A major challenge in the successful introduction of ceramic parts into a gas turbine is the design of the interface between the ceramic parts and metallic hardware. A turbine blade, which incorporated a dovetail root, was designed with such considerations. A relatively thin compliant layer between the ceramic-metallic loading surface was considered for equalizing pressure face load distributions. Five monolithic siliocn nitride ceramic materials were considered: AS800 and GN10, AlliedSignal Ceramic Components; NT164, Norton Advanced Ceramics; SN281 and SN253, Kyocera Industrial Ceramics Corporation. The probability of survival using NASA/CARES for 30,000 hours of engine operation was calculated for each material. The blade frequencies, stresses, and temperatures were predicted. The influence of the dovetail angle was also analyzed to determine the most optimum configuration. Prior to engine installation all blades underwent extensive nondestructive evaluation and spin proof testing. This paper will review the design, life prediction, and testing of the first stage ceramic turbine blade for the Solar Turbines Centaur 5OS engine.

Full textAbstract:
This paper will review the Taurus 65 gas turbine product, the newest member of Solar Turbine’s product line. The Taurus 65 is a 6.3 MW, 32.9% efficient single shaft gas turbine specifically designed for the combined heat and power (CHP) market with low emissions and excellent exhaust heat capacity. It leverages the reliability and durability of the Centaur® and Taurus product technology. The 13-stage compressor includes the Centaur 50 compressor plus two new aft stages. The combustion system adopts Solar’s proven SoLoNOx™ technology and has a guaranteed NOx emission of 15 ppmv (15% O2). The newly designed three-stage turbine incorporates the proven Taurus 70 high efficiency design with advanced cooling and material technologies developed in the Mercury™ 50 turbine engine. Solar developed a new Taurus 65 package system design utilizing 6 Sigma methodologies. The new design incorporates features that allows for quick installation and easy operation and maintenance. A Kaizen service event successfully demonstrated the field maintenance and engine removal on the first package built. The Taurus 65 universal package design will become the standard design for the Centaur 40, Centaur 50 and Taurus 60 products, and will have the same footprint as the current Taurus 60 package. The first Taurus 65 gas turbine started development test during the fourth quarter 2004. The development test results have been excellent. A Taurus 65 gen-set unit will start endurance testing during the third quarter 2005 at Solar’s San Diego facility. The first production unit will be available for shipment in the first quarter 2006. The New Product Introduction (NPI) process, 6 Sigma process, and Kaizen processes were utilized during the product design, development and introduction phases.

Full textAbstract:
Currently, industrial countries generate most of their electricity in large centralized plants. These plants have excellent economies of scale, however, they usually transmit electricity through long distances and can affect the environment. Distributed generation is another approach that reduces the amount of lost energy during transmission as the electricity is generated closely to where it is used, this way reducing the size and number of power lines to be constructed. The current technologies in DG include small gas turbine engines, internal combustion reciprocating engines, photovoltaic panels, fuel cells, solar thermal conversion and Stirling engines using fossil fuels and bio-fuels. Among them, small gas turbine engines are a promising technology for the implementation of distributed generation systems in the near future. This work presents the results of the preliminary compressor design of a simple cycle gas turbine engine, obtained with the use of a straightforward one-dimensional FORTRAN code, which enables to calculate the main characteristics of a centrifugal compressor by means of the application of non-dimensional parameters, with a vast reduction of computational time. The results obtained were compared with a CFD analysis and with experimental results taken from specialized literature; therefore a reasonable agreement was reached. The main contribution of this paper is to demonstrate that by the use of a simple code it is feasible to obtain fairly close results in comparison with those which can be obtained by laborious iterative processes such as those developed through the analysis using CFD techniques.

Fort Huachuca, AZ, located 60 mi Southeast of Tucson, has had over 30 years of experience with various renewable energy systems. This session discusses lessons learned from the successes and failures in that experience, including: an indoor pool solar water heating system (installed 1980); a solar domestic hot water (DHW) system (installed 1981); a grid connected Photovoltaic system (installed 1982); transpired air solar collectors (Solarwalls,™ installed 2001); day-lighting (installed 2001); a 10-KW wind turbine (installed 2002); photovoltaic powered outdoor lighting (installed 1994); a prototype Dish/Stirling solar thermal electric generator (installed 1996); two 30-KW Building Integrated Photovoltaic systems (installed on new membrane roofs in 2009); and a 36-KW Photovoltaic system moved from the Pentagon in June 2009 and became operational November 2009 at Fort Huachuca. Also discussed is an experimental solar attic system (first installed in 2003 and now being fully monitored) that collects hot air in an attic, and via a heat exchanger and tank, produces solar DHW. This paper discusses system design, installation, metering, operation and maintenance, and also work in progress on the installation of commercial, off-the-shelf 3-KW Dish/Stirling solar thermal electric generators and solar thermal/natural gas-to-electric systems at a central plant. Discussions include biogas (methane from a wastewater digester) and biomass (wood chip boiler) being installed at a central heating/cooling plant.

Full textAbstract:
In order to explore the deep space, such as Mars, Jupiter, Saturn, etc in the future, a spacecraft that will be driven by nuclear power should be developed [1]. At present, satellites or space probes have been using mainly electric source of chemical battery, fuel battery, solar battery, and RI battery. However, considering highly developed and extensive space exploration in the future, it is obvious that larger electric power is required over the long term space travel more than several years. Additionally, the solar battery used in space will be fundamentally impossible to use in planetary exploration father away form Mars because sunlight is attenuated. Therefore, lager electric power source must be installed in the space craft. In this study, we consider about co-generation system for heat and electricity using nuclear power. We think that the nuclear power is appropriate for using in deep space because of a long time operation without refueling and possibility in downsizing due to higher power density. We selected the fast reactor system of about 18 MWth compared with other type of reactors, such as PWR and high temperature gas reactor [2]. With regard to a power generation system, we examined about efficiency of Stirling engine compared with a gas-turbine engine. Theoretical efficiency of Stirling engine [3] is much higher than that of gas-turbine engine. Therefore, we selected Stirling engine and we have started the model test of a Stirling engine. Total power generation at International Space Station (ISS) that has been built since 1998 is about 110kWe. We estimated that about 5times as much electricity as that of ISS is enough to explore or develop the space. In that case, 2.5MWe will be generated by the system, number of crews will be about 10 and 2MW will be used to electric propulsion.

Full textAbstract:
This paper presents the development of a new experimental facility for analysis and optimization activities on smart polygeneration grids. The test rig is being designed and built in the framework of the European project “Energy-Hub for residential and commercial districts and transport” (E-HUB), which targets optimal energy management of residential and commercial districts. The experimental rig, named “Energy aNd Efficiency Research Demonstration District” (E-NERDD), is located inside the University campus in Savona, and is based on four different prime movers able to produce both electrical and thermal energy: a 100 kWe micro gas turbine, a 20 kWe internal combustion engine, a 3 kWe Stirling engine, and a 450 kWe fuel cell/gas turbine hybrid system emulator based on the coupling of a micro gas turbine with a modular vessel. While the electrical side is based on the connection with the campus grid (further developments are planned for a local electrical grid including storage units), thermal energy is managed through a dual ring-based water distribution system. The facility is also equipped with thermal storage tanks and fan cooler units to study and optimize different thermal management algorithms generating different thermal load demands. The facility also includes an absorption chiller for cold water generation. As a result, trigeneration operation is possible in a physically simulated urban district. Moreover, the rig is equipped with six photovoltaic panels (significant for the electrical aspects) and 10 kWp of thermal solar panels to be integrated in the grid. Further technologies to be considered for the E-NERDD are power plants based on other renewable resource (e.g. with biomass fuel). These systems are planned to be analyzed through real plants (remote connection with the field) or through virtual models based on real-time dynamic approaches. Experimental tests related to the performance of the micro gas turbine are reported and discussed in this paper. The focus here is on machine correction curves essential to evaluate factors for quantifying ambient temperature influence on machine performance. This analysis is essential for setting the thermal distribution grid and for future optimization tests.
