Abstract:
The issue of measuring and determining the calorific value of fuels is related to thermodynamic analysis of the effects of the combustion process aimed at determining the amount of heat transferred to the environment. Currently, there are several methods for determining the calorific value of fuels and their methodology is related to the type of fuel being analyzed. These methods are quite complicated and require the use of specialized measuring equipment. The energy demand of modern civilization along with the need to protect the natural environment prompts the search for new ways to generate energy directed at sources other than conventional fossil fuels. Technologies related to the use of biogas, synthesis gas obtained in biomass or waste gasification processes are being introduced. The use of these fuels in industrial processes of generating heat and electricity requires caloric stability of the fuel. The caloric stability of the fuel is necessary to ensure the stability of thermal energy conversion processes that translate directly into the set values of generated electricity using electric machines. One way to assess the energy quality of a fuel is to measure its calorific value. There are several methods for determining the calorific value of a fuel, but they all require special measurement conditions. The article presents the author’s concept of a calorimeter dedicated to the analysis of the calorific value of gaseous fuels.

Abstract:
The production of an improved sawdust briquette, as an alternate source of fuel has been achieved. In addition to sawdust other constituents of the briquette were silica (sharp sand), starch and kerosene. The density, ash content, calorific values and moisture content of briquette were determined. The composition of starch and kerosene was constant throughout the experiment. It was observed that as silica percentage was increased, there was an increase in the briquette calorific value until maximum value of 20%. The sample which gave the best calorific value was with percentage compositions of 60% sawdust, 20% silica (sharp sand), 5% kerosene and 15% starch with a calorific value of 12.68mJ/kg .The produced briquette had a higher calorific value than wood and other agro waste it was compared with.

Abstract:
In order to show the fuel-saving effect of Plug-in Hybrid Electric Vehicle (PHEV) [1]more intuitively, three conversion methods of fuel and electricity were introduced considering different aspects, namely conversion method of simple calorific value, comprehensive calorific value and carbon dioxide emission. Firstly, the energy consumption of two mainstream PHEVs according to the current domestic (China) energy consumption test regulation were tested [2], then the tested values were converted by the three conversion methods to get the equivalent fuel consumption. What’s more, by the introduction of pure electricity Utilization Factor (UF) [3], the fuel consumption of PHEV at two stages (pure electric driving and pure fuel driving) were weighted to obtain the comprehensive fuel consumption. The effects of different conversion methods on fuel consumption were analyzed, and the results were compared horizontally with that of traditional fuel vehicles. The result shows that the comprehensive fuel consumption of PHEV converted by the method of carbon dioxide emission is the highest. Secondly, from the perspective of comprehensive calorific value, PHEV has obvious fuel-saving effect and a better development prospect comparing with traditional fuel vehicle. Last but not the least, PHEV has a significant fuel-saving advantage over traditional fuel vehicle in areas where the proportion of thermal power generation is relatively low, and with the continuous decrease of the overall proportion of thermal power generation, the fuel-saving effect of PHEV will become more and more obvious.

Abstract:
In recent years biofuels have obtained a considerable interest, due to the implementation of ruling and gradual replacement of fossil fuels. One of production steps at gaining the oil is a pressing process. Wastes come into being from this process. These wastes are used as feed, fertilizer prospectively as fuel. A contemporary scientific literature pays attention namely to one of prospective produces which is a produce of the tropical and subtropical zones Jatropa curcas. Tests were performed at Jatropha Curcas seeds of a brown colour (that means gnaw). The aim of a research is an analysis of Jatropa curcas seed from the utilization point of view of the gross calorific value. The basic instrument to evaluate the gross calorific value of each variant of the experiment was a calorimeter PARR 6200 and digital scales for accurate laboratory weighing.

Abstract:
Information on calorific value is very important factor in fuel evaluation. The objective of the study was to investigate the calorific values of the leaves of five (5) selected trees species of dipterocarp in Piah Forest Reserve, Perak, Malaysia. The species are Hopea sp., Shorea parvifolia, Shorea leprosula, Shorea macroptera and Dipterocarpus sp. The calorific values were determined using the Adiabatic Bomb Calorimeter. The difference of calorific value between the five species were also examined. It was found that, the mean calorific value for the dipterocarp species were within the range of 4041.28 Cal g-1 to 4820.78 Cal g-1. The leaves of the Shorea macroptera contain higher calorific value compared to other four species. The findings will be useful in the preparation of forest fire management plan, and also in the development of bioenergy project of wood-based biomass from forest species.

Abstract:
The waste treatment, particularly the thermal treatment of waste has changed fundamentally in the last 20 years, i.e. from facilities solely dedicated to the thermal treatment of waste to facilities, which in addition to that ensure the safe plant operation and fulfill very ambitious criteria regarding emission reduction, resource recovery and energy efficiency as well. Therefore this contributes to the economic use of raw materials and due to the energy recovered from waste also to the energy provision. The development described had the consequence that waste and solid recovered fuels (SRF) has to be evaluated based on fuel criteria as well. Fossil fuels – coal, crude oil, natural gas etc. have been extensively investigated due to their application in plants for energy conversion and also due to their use in the primary industry. Thereby depending on the respective processes, criteria on fuel technical properties can be derived. The methods for engineering analysis of regular fuels (fossil fuels) can be transferred only partially to SRF. For this reason methods are being developed or adapted to current analytical methods for the characterization of SRF. In this paper the possibilities of the energetic utilization of SRF and the characterization of SRF before and during the energetic utilization will be discussed.

Abstract:
Sri Lanka is an island at the Indian Ocean with 65234 km2 and it has a power demand of 2000 MW. The hydro power was the main power source before year 2000, after maximum usage of hydro power Sri Lanka installed fossil fuel power plant to achieve the demand. Then the electricity price gradually increased due to higher increment of fuel price. As the solution for this higher price of electricity the government has to go to new profitable power source the coal power. Finally year 2011 Puttalam coal power plant 300 MW x 1 was installed with the hope of providing the low cost reliable energy supply to Sri Lanka and it will be extended to 300MW x 3 plan in year 2015. Therefore the puttalam coal power plant is the key power plant to the Sri Lankan power generation and it is expected to have the maximum output (base load) to the Power demand of Sri Lanka. Sri Lanka is a tropical country and it has two different weather seasons as rainy season and dry season. The puttalam power plant situated at Kalpitiya peninsula and it has normally dry weather condition, Months of April, October November and December have heavy rain condition (Meteorological Department, Sri Lanka, 2012). The puttalam coal power plant may not achieve full load because of high moisture content at rainy season. So this Thesis carried out to find the capability to achieve the full load with available plant, plant capacity by using different coal qualities. Then find the economical benefits and effect on the environment with the recommended coal for different seasons and also design a storage plan to coal storage at existing coal yard. Based on the historical data and the Meteorological department rain fall data and by doing a technical analysis the recommended coal type was selected and the capability of plant equipment capacity to the recommended coal to achieve the full load was analyzed. Then the coal storage plan was designed according to annual requirement of the different recommended coal and economical benefit was analyzed by considering last year cost for generated power and the generation cost, if recommended coal is used for last year. Finally flue gas analysis was carried out for the recommended coal to find the effect on the environment. The recommended coal for rainy season is with the heating value of 6600 kcal/kg and for dry season it is 6300 kcal/kg. The capacities of main boiler and other plant equipments are capable for the recommended coal to achieve the full load of the plant. Then the design of the coal storage plan was given under figure 4.2 and table 4.1. It was calculated that a profit of 3.932 million US$ can be achieved by using the recommended  coal for the last year and also when compared with the changing price of oil and coal it will be more profitable for the future. Because the oil price increases very rapidly and the increase in coal price is very low compared to the oil price. Finally the SOx and NOx emissions from recommended coal were analyzed and it was within the environmental limits because of the high quality emission reduction plant equipments.

Abstract:
AbstractThe need for emission reduction for climate management had triggered the application of pyrolysis technology on firewood that yield bio-oil, bio-char, and syngas. The purpose of present study was to select the best bio-oil and bio-char producing plants from 17 firewood tree species and to quantify the amount of carbon storage. A dried and 1 mm sieved sample of 150 g biomass of each species was pyrolyzed in assembled setup of tubular furnace using standard laboratory techniques. The bio-oil and bio-char yields were 21.1–42.87% (w/w) and 23.23–36.40% (w/w), respectively. The bio-oil yield of Acacia seyal, Dodonea angustifolia, Euclea schimperi, Eucalyptus globulus, Casuarina equisetifolia, and Grevillea robusta were over 36% (w/w), which make the total yield of bio-oil and bio-char over 62% (w/w) of the biomass samples instead of the 12% conversion efficiency in traditional carbonization. The calorific value of firewood was 16.31–19.66 MJ kg–1 and bio-oil was 23.3–33.37 MJ kg–1. The use of bio-oil for household energy and bio-char for carbon storage reduced end use emission by 71.48–118.06%, which could increase adaptation to climate change in comparison to open stove firewood by using clean fuel and reducing indoor pollution.

Abstract:
Reduction of conventional fuel has encouraged to find new sources of renewable energy. Oil produced from the pyrolysis method using biomass is considered as an emerging source of renewable energy. Pyrolytic oil produced in pyrolysis needs to be upgraded to produce bio-oil that can be used with conventional fuel. However, pyrolytic oil contains high amounts of oxygen that lower the calorific value of fuel, creates corrosion, and makes the operation unstable. On the other hand, the up-gradation process of pyrolytic oil involves solvent and catalyst material that requires a high cost. In this regard, the co-pyrolysis method can be used to upgrade the pyrolytic oil where two or more feedstock materials are involved. The calorific value and oil yield in the co-pyrolysis method are higher than pyrolytic oil. Also, the upgraded oil in the co-pyrolysis method contains low water that can improve the fuel property. Therefore, the co-pyrolysis of biomass waste is an emerging source of energy. Among different biomasses, solid waste and aquatic plants are significantly used as feedstock in the co-pyrolysis method. As a consequence, pressure on conventional fuel can be reduced to fulfill the demand for global energy. Moreover, the associated operating and production cost of the co-pyrolysis method is comparatively low. This method also reduces environmental pollution.

Abstract:
Automobile vehicles are the main sources of environmental pollution, especially those with diesel engines. They cause a number of health diseases and harm to the ecosystem. Biofuels are a suitable alternative fuel for IC engines which have potential to reduce engine emissions with more or less equal performance of the petroleum fuels. Though Biodiesel is suitable for Diesel engines, it suffers with high density, lesser calorific value, high fuel consumption and increased emissions of nitrogen. However, additives minimize the deteriorating factors of the Biodiesel and maintain the international pollution norms. Many different types of additives are used with the diesel and (or) biodiesel to enhance performance and to improve its quality. The researchers conclude that the use of additives along with diesel and biodiesel improves the performance and reduction in emission. This review discusses effects of additives with diesel and biodiesel on the performance and emission characteristics of Diesel engines.

Abstract:
The management of municipal solid waste (MSW) is a major obstacle for the majority of municipalities in developing countries because of the impacts related to the landfilling of waste. Garbage is an energy-rich material. As a result, energy recovery is considered to be a sustainable waste management method. In Morocco, 7.4 million tons are produced annually; most of the waste is landfilled without any recovery despite the impacts related to this method of disposal. The objective of this chapter is to characterize combustible fractions (RDF) from household waste in Morocco and to study the economic and environmental benefits of their use as alternative fuels in cement kilns. The results of this research show that the combustible fractions contained in household waste in Morocco constitute a potential sustainable energy source with a high lower calorific value (4454 kcal/kg). The study of the advantages of co-incineration shows that the substitution of pet coke by 15% RDF reduces the pollution linked to gaseous emissions. In addition, the cement plant can make financial savings 389 USD/h by minimizing the use of fossil fuels.

Abstract:
Distributed Combustion offers significant potential for improved performance and near zero emissions for gas turbine and other industrial applications. Our quest for zero emission distributed combustion is further explored here by utilizing swirl to the flow. The beneficial aspects of distributed swirl combustion are examined with special focus on near zero emissions of NO and CO, and significantly improved pattern factor of the combustor using low calorific value fuel. Methane gas diluted with inert gas is used to simulate the low heating value fuel. A cylindrical geometry is used for combustor with air injected tangentially to impart swirl to the flow. The combustion behavior is evaluated using normal and preheated air at inlet to the combustor. Experimental results from the distributed combustor design using methane fuel showed low levels of NO (&lt;8PPM) and low CO (∼21PPM) under non premixed conditions at an equivalence ratio of 0.7 and high heat release intensity of 36MW/m3-atm. With preheated air to the combustor, results showed overall NO levels of &lt;15PPM and CO ∼12 PPM for non premixed combustion at an equivalence ratio of 0.6 under high heat release intensity of 27MW/m3-atm. Low heating value gas resulted in a dramatic decrease in NO emissions (30–50%) with minimal effect on CO for all the conditions examined here. Results obtained with different calorific value fuels on the emissions of NO and CO, lean stability limit and OH* chemiluminescence are presented.

Abstract:
During the summer, power output and the efficiency of gas turbines deteriorate significantly. Gas turbine inlet air fog cooling is considered a simple and cost-effective method to increase power output as well as, sometimes, thermal efficiency. During fog cooling, water is atomized to micro-scaled droplets and introduced into the inlet airflow. In addition to cooling the inlet air, overspray can further enhance output power by intercooling the compressor. With continued increase of volatility of natural gas prices and concerns regarding national energy security, alternative fuels such as low calorific value (LCV) synthetic gases (syngas) derived from gasification of coal, petroleum coke, or biomass are considered as important common fuels in the future. The effect of fogging/overspray on LCV fuel fired gas turbine systems is not clear. This paper specifically investigates this issue by developing a wet compression thermodynamic model that considers additional water and LCV fuel mass flows, non-stoichiometric combustion, and the auxiliary fuel compressor power. An in-house computational program, FogGT, has been developed to study the theoretical gas turbine performance by fixing the pressure ratio and turbine inlet temperature (TIT) assuming the gas turbine has been designed or modified to take in the additional mass flow rates from overspray and LCV fuels. Two LCV fuels of approximately 8% and 15% of the NG heating values, are considered respectively. Parametric studies have been performed to consider different ambient conditions and various overspray ratios with fuels of different low heating values. The results show, when LCV fuels are burned, the fuel compressor consumes about 10–18% of the turbine output power in comparison with 2% when NG is burned. LCV fueled GT is about 10–16% less efficient than NG fueled GT and produces 10–24% of net output power even though LCV fuels significantly increase fuel compressor power. When LCV fuels are burned, saturated fogging can achieve a net output power increases approximately 1–2%, while 2% overspray can achieve 20% net output enhancement. As the ambient temperature or relative humidity increases, the net output power decreases. Fog/overspray could either slightly increase or decrease the thermal efficiency depending on the ambient conditions.

Energetic valorization of thermoplastic wastes (High-density polyethylene (PE) and Polypropylene (PP)) to produce fuel using pyrolysis process is presented in this paper. HDPE and PP pyrolysis experiments were carried out in a lab-scale batch reactor under an inert atmosphere. Nitrogen gas was used as carrier before and during the experiments. The temperature was varied from 293 K to approximately 773 K. The viscosities of HDPE, PP and the mixture 50% HDPE &amp; 50 % PP pyrolysis liquids are respectively equal to 1.08 cP, 0.67 cP and 0.8 cP. Its densities are respectively equals to 0.735, 0.751 and 0.759 (at 20 °C–30 °C). The high calorific value (the heating Value) is respectively equals to 45.235 ± 0.641 MJ/kg, 46.151 ± 1.33 MJ/kg and 45.393 ± 0.87 MJ/kg. The liquids obtained have approximately the same Kerosene (Coal Oil) high calorific value (46 MJ/kg). The flash points are respectively equal to 32 °C, 31 °C and lesser than 25 °C for the mixture. They are lesser than coal oil and Diesel values which are equal to 38 °C for Kerosene and between 38 °C and 58 °C for Diesel. The mixture of two polymers decreases the viscosity values comparing to coal oil (1.7 cP) and Diesel (3.35 cP).

Abstract:
Abstract The current paper presents an extension of the fuel flexibility of the Siemens SGT-300 Dry Low Emissions combustion system to include High Calorific Value fuels, achieved using the engine’s current standard combustion hardware. Results from high pressure rig tests show that the standard SGT-300 DLE combustor can reliably operate on High Calorific Value fuels with temperature corrected Wobbe Index up to 63MJ/m3, which corresponds to Grade A LPG (60%vol. C3H8, 40%vol. C4H10). Metal temperatures of the combustion hardware when operating on High Calorific Value fuels are within life acceptance criteria for the Siemens SGT-300 industrial gas turbine. NOx emissions throughout the load range of the engine comply with the EU Industrial Emissions Directive. At part load, a reduced requirement for piloting compared to Natural Gas yields relatively low temperatures at the burner face and low NOx emissions. NOx emissions at full load, which tend to increase with increasing heating value, are higher than for Natural Gas but lower than for diesel and heavy fuel oils.

Abstract:
The development of integrated, coal-gasification combined cycle (IGCC) systems provides cost-effective and environmentally sound options for meeting future coal-utilizing power generation needs in the world. The Japanese government and the Electric Power Industries in Japan promoted research and development of an IGCC system. We have being working on developing a low-NOx combustion technology used in gas turbine combustors for IGCC. Each gaseous fuel produced from some raw materials contained CO and H2 as the main combustible components, and a small amount of CH4. Compositions and calorific values of gasified coal fuels varied widely depending on raw materials and gasifier types. Gaseous fuel, produced in various gasifiers, has a calorific value of 4–13MJ/m 3, which is about one-tenth to one-third that of natural gas. The flame temperatures of fuels increase as the fuel calorific value rises. When the fuel calorific value rises 8MJ/m 3 or higher, the flame temperature is higher than that of natural gas, and so NOx production from nitrogen fixation is expected to increase significantly. Also, some gasified coal fuels contain fuel nitrogen, such as ammonia, if the hot/dry type gas cleaning system is employed. These factors affect the combustion characteristics of the gasified coal fuel. In this paper, we clarified the influence of gasified coal fuel properties on NOx and CO emissions through experiments using a small diffusion burner and through numerical analysis based on reaction kinetics. The main results were as follows: (1) NH3 conversion to NOx increases with increasing CH4 concentration in gaseous fuel. (2) If gaseous fuel contains CH4, there will be some specific equivalence ratio in the primary combustion zone for the minimum NH3 conversion to NOx in the two-staged combustion. (3) Its specific equivalence ratio in the primary combustion zone increases with decreasing CH4 concentration in gaseous fuel. (4) If the fuel contains a small percent of CH4, there is no influence of the CO/H2 molar ratio in the fuel on the conversion rate of NH3 to NOx, while there is an influence in the case where fuel contains no CH4. The conversion rate increases with rises in the CO/H2 molar ratio. (5) As the pressure increases, the conversion rate of NH3 to NOx slightly decreases and the CO emission declines significantly.

Abstract:
Coal gas and biofuels as alternative fuels have recently become more attractive, because of their benefits, especially in electrical power industry. The major obstruction to their use is the relatively low calorific values. This paper presents a comprehensive simulation method for calculating the adiabatic temperature of various fuels when they are used in combustion chambers under constant pressure. The adiabatic temperature is presented as a function of combustion fuel air ratios and the fuels low calorific values. In addition, the utilization of various gaseous fuels in single shaft and two shaft gas turbine engines is analyzed. This analysis includes the design point (DP) and off-design (OD) performance of the two engines. The calorific values of the four gases investigated correspond to natural gas (NG) and to fuels with significantly lower calorific values than that of NG (coal synthetic gases, biofuels). Two main conclusions are drawn from this analysis. Firstly, for both single shaft and two shaft engines and for a given turbine entry temperature (TET), both power and thermal efficiency are increasing when fuels with decreasing calorific value are burnt. Secondly, for both single shaft and two shaft engines and for a given power, the thermal efficiency is slightly reduced.

Abstract:
Abstract Low calorific value (LCV) gaseous fuels are generated as by-products in many commercial sectors, e.g. as mine gas or bio-gas. Their efficient exploitation can be a considerable source of primary energy. Typically, product gases from biomass are characterized by low lower heating values (LHV) due to their high concentration of inert gases and steam. At the same time, their composition varies strongly based on the initial feedstock and may contain unwanted components in the form of tars and ammonia. These properties make the design of appropriate combustion systems very challenging and issues such as ignition, flame stability, emission control, and combustion efficiency must be accounted for. By employing a proprietary gas turbine burner at the TU Berlin, the combustion of an artificial LCV gas mixture at stoichiometric conditions has been successfully demonstrated for a broad range of steam content in the fuel. The current work presents the stability maps and emissions measured with the swirl-stabilized burner at premixed conditions. It was shown that the flame location and shape primarily depend on the steam content of the LCV gas. The steam content in the fuel was increased until flame blow-out occurred at LHVs well below the target condition of 2.87 MJ/kg (2.7 MJ/mN3). The exhaust gas is analyzed in terms of the pollutants NOx and CO for different fuel compositions, moisture contents, and thermal powers. Finally, OH* measurements have been carried out in the flame. A simple reactor network simulation was used to confirm the feasibility of the experimental results.

Abstract:
Adiabatic flame temperature is of significant importance for the design of a GT combustor, as it is the temperature under the condition of no heat loss takes place from the combustion system. This importance arises from the fact that it plays an important role in the pollutants emitted from the system, such as carbon oxides and nitrogen oxides. Additionally, the temperature also affect the thermal stresses set up in the combustion system, such stress may lead to the deterioration of the chamber if not well controlled. Consequently, it is essential before the construction of the combustion chamber, a simulation process for the temperature distribution within the combustion system to be carried out, in order to avoid local thermal stresses and to minimize nitrogen oxides and carbon dioxides emissions, pollutants of great concern, that are very dependent on the flame temperature. The factors that predominantly affect the adiabatic flame temperature are the fuel heating value, the type of oxidant, FAR, the temperature of the reactants, the amount of oxygen in the air, as well as the dissociation phenomena. In this study, a code in FORTRAN programming language is developed for the calculation of the adiabatic flame temperature. The simulation is performed for different gaseous fuels of low calorific value, for air preheat, for fuel preheat, as well as for various Φ. From the simulation resulted that Tad and Φ for each fuel are totally dependent on the fuel’s calorific value. Both for the case of the air preheat, and the fuel preheat temperature it was observed increase of the Tad. Preheating of combustible mixture by recycling heat from flue gases has been considered an effective technology not only for combustion of low calorific fuels but also for fuel conservation.

Abstract:
A model minimising Gibbs Free Energy is used to examine the thermodynamic limits of performance of a gasifier for biomass and other alternative fuels. The minimisation of free energy is highly flexible in that it allows a large number of species to be examined. Such an equilibrium model gives insight into the differences in the behaviour of coal and biomass in gasifiers. Biomass differs from coal in terms of heating value, ash, volatile and carbon contents and the amount of elemental oxygen. The model has been used to explore, entirely from a thermodynamic viewpoint: (i) the off-gas compositions, (ii) the impact of process variables on the heat balance and when gasification is complete, (iii) the effect of different gasification agents on process performance and (iv) optimisation of the calorific value of the hot and cold gas produced. Dried sewage sludge was used as a typical biomass fuel for these simulations. For biomass fuels with a low calorific value, it is shown that co-gasification with a support-fuel of higher calorific value, for example coal, is more practicable than gasification of the biomass alone.
