Experimental evaluation shows KFME20 enhances efficiency in gas turbine systems, suggesting its potential as an aviation fuel.
Key Points
This research aims to investigate the performance characteristics of light-duty gas turbine engines using biodiesel blends to improve efficiency and emissions.
Investigated five biodiesel blends (KFME20, KFME40, KFME60, KFME80, and KFME100) in a light-duty gas turbine engine.
Evaluated performance metrics such as thermal efficiency, thrust-specific fuel consumption, and emissions behavior under varying engine loads.
Experimental conditions assessed the effects of blending ratios on combustion efficiency and emissions.
KFME20 achieved the highest thermal efficiency, improving by up to 27.8% compared to neat KFME, due to better oxygen-fuel mixing and enhanced atomization.
KFME20 also reduced thrust-specific fuel consumption (TSFC) by about 20%, indicating improved energy conversion.
Higher biodiesel concentrations increased NOₓ emissions due to elevated combustion temperatures, with KFME20 and KFME40 recommended for low emission limits.
