“…As consequence, more SGB is absorbed by the wick during combustion compared to FGB. This result is in good agreement with [11], who conducted a flame temperature analysis of biodiesel. Nevertheless, as the percentage of SGB increased in the DD, eventually the flow rate decreased as well.…”

“…In addition, the formation of yellow smoke is lower for SGB which is an indication of complete combustion compared to FGB100. This is because soot formation decreased when the level of unsaturated fatty acid decreased in the fuel composition [11]. In terms of flame length, SGB20 is proved to be suitable to replace distillate diesel.…”

“…Similar results are reported by Glaude, Fournet [13], where the adiabatic flame temperature of the FAMEs is higher than natural gas and close to diesel fuel. This is because biodiesel has a higher oxygen content than fossil diesel, which leads to more complete combustion and hence leads to a greater flame temperature [11]. However, SGB has recorded the highest temperature for SGB50, followed by SGB80.…”

“…Additionally, SGB has a higher calorific value than FGB, thus SGB and its blends produced more thermal energy than FGB. However, Jha, Fernando [11], have reported that increase or decrease of flame temperature is associated with more of the oxygen content of the fuel being used, rather than calorific value. In fact, this statement is in line with the emissions results, where SGB50 and SGB80 have consumed more oxygen than other blends.…”

Biodiesel is considered as an alternative fuel for gas turbine application; however, the properties of biodiesel need further improvement in order to meet the combustion dynamics of a typical gas turbine. Therefore, this work has addressed an alternative and inexpensive method of performing combustion studies of such improved biodiesel. A diffusion burner which has similar combustion dynamics to a gas turbine combustor has been used to evaluate the combustion characteristics of improved biodiesel or Second Generation Biodiesel (SGB). The combustion characteristics of the improved biodiesel have been evaluated in terms of fuel burning rate, flame length and emissions. Subsequently, the results were compared with unimproved biodiesel or First Generation Biodiesel (FGB) and distillate diesel (DD). The results indicated improvement in physical properties; SGB and its blends possess better combustion characteristics in terms of flame length, mass of fuel flow rate and emissions compared to FGB and DD. Improvements in physical properties such as viscosity and density cause SGB fuel to possess better capillary flow than FGB. Additionally, lower carbon monoxide (CO) emissions indicate that SGB has more complete combustion than FGB. On other hand, SGB with higher saturation compounds has produced higher thermal energy with lower nitrogen oxides (NO x ) compared to FGB. Thus, SGB can be considered as an alternative fuel for use in gas turbines and a 50% blend of SGB with DD has shown promising results compared to other blend ratios.

“…Hashimoto et al carries out combustion characteristic of palm methyl ester for gas turbine combustor at atmospheric pressure and high temperature air (617 K) and found that adiabatic flame temperature, emission CO 2 , CO, UHC and NO x were lesser than conventional diesel [9]. Saroj et al carried out flame temperature analysis for biodiesel blends and found encouraging results in term of increased flame temperature and reduced emissions [10]. Erazo et al studied atomization and combustion characteristic using canola methyl using an airblast atomizer at atmospheric pressure and temperature 600 K. They found that NO x emissions are lowered in biodiesel compared to the conventional diesel [11].…”

Scarcity of fossil fuels and their negative impact on environment drive the research in the field of alternative fuels. Biodiesel is one such promising alternative fuel that is used in automobile, gas turbine, boiler and other furnace applications. In the present study, combustion characteristics of biodiesel (Jatropha methyl ester) and its diesel blends in gas turbine like combustor have been studied experimentally. An airblast atomizer along with axial swirler (swirler no. 0.76) is employed to investigate the combustion characteristics. During the experiment, heat rate (24 kW), Air to liquid ratio (ALR=2) and air temperature (600K) was kept constant. For different equivalence ratio, spray and flame characterization, flame temperature, combustion efficiency and emission parameters such as carbon dioxide (CO 2 ), Carbon monoxide (CO), Nitrogen oxide (NO x ) and unburned hydrocarbon (UHC) were determined. It is found that the flame temperature increases with increase in JME percentage in diesel whereas and major pollutants such as CO, CO 2 and UHC emissions decrease but the NOx emissions increases. The obtained results indicate that the biodiesel can be promising fuel for gas turbine power plants instead of fossil fuels.

In recent years, the interest to use biodiesel as a substitute for mineral diesel has been increasing steadily. Biodiesel is a renewable fuel, consisting of various fatty acid methyl esters with the exact composition depending on the feedstock. This is a distinctly different composition than the hydrocarbon content of mineral diesel. In spite of that, biodiesel has many properties very close to those of mineral diesel. Consequently, the required biodiesel-related modifications of the diesel engine are typically rather minor. On the other hand, because of its different chemical character, biodiesel has several properties, which differ from those of mineral diesel just enough to offer an opportunity to reduce harmful emissions without worsening other economy and engine performances. It should be noted, however, that biodiesel properties may depend heavily on its raw materials. Biodiesel SourcesBiodiesel is derived from renewable resources, such as vegetable oils, animal fats, and waste restaurant greases. Biodiesel is an environmentally friendly alternative fuel, but typically comes at a higher price than mineral diesel (Demirbas 2008a(Demirbas , 2009). The cost of biodiesel varies in dependence on the base stock, geographic area, variability in crop production from season to season, the price of the crude petroleum, and other factors.The typical raw materials for biodiesel are oils from rapeseed,
