Experimental analysis on emission production and performance of stressed 100 % SPK, stressed Fully Formulated Synthetic Jet Fuel and Jet A-1 in a small gas turbine engine

Increasing emissions and depleting fossil fuel resources have led to concerns over the sustainability of conventional jet fuel and growth in research on alternative fuels. One of the strategies in the field for further research is to check the performance and emissions of gas turbine engines by using different alternative fuels. 100 % SPK and Fully Formulated Synthetic Jet Fuel appear to be attractive alternative fuels for gas turbine engines due to their similar properties as Jet fuel. This paper presents the results of an experimental study done on a small gas turbine engine, burning conventional Jet A-1 fuel, thermally stressed 100 % SPK and Fully Formulated Synthetic Jet Fuel. Emissions have been measured at engine exit plane. Comparison of emissions and performance parameters of different alternative fuels have been presented in the paper. A detailed analysis on emissions (CO, CO₂, NO, NO₂, NO_x, Smoke and particulate) and performance of 100 % SPK, Fully Formulated Synthetic Jet Fuel, Jet A-1 has been presented and compared. Substantial reduction in smoke and particulate emissions is observed for 100 % SPK as compared to conventional Jet A-1 and Fully Formulated Synthetic Jet Fuel due to lower aromatic content.
