Performance and Emissions of a Micro-Turbine Fueled with JP8-Canola Biodiesel Mixtures

In this study, a micro gas turbine was operated with JP8 and canola biodiesel blends. The blends tested were JP8, 40% of biodiesel, 60% of biodiesel, and 80% of biodiesel by volume. The turbine was run at 3 speeds, 60.000, 80.000 and 105.000 rpm. Engine power generation and emissions performance were determined. The results reveal that as biodiesel content in the fuel mixture increased, the fuel flow rate increased to maintain the constant speed operation and equivalence ratio reduced. It was shown that TJ35 engine can operate with biodiesel blends in JP8 without sacrificing thrust. In fact, 80% biodiesel blend increased the thrust at 105.000 rpm by 2% compared to JP8. Exhaust gas temperatures slightly reduced with increasing biodiesel content. Higher biodiesel blends resulted in higher CO2, CO and CxHy emissions while O2 emissions reduced. This study demonstrates that a micro gas turbine engine could be operated successfully with JP8-canola biodiesel blends, which means the engine could be utilized in distributed and remote off-grid locations for power generation by burning renewable biodiesel fuels.Copyright
