Spray combustion characteristics of alternative liquid fuels

Cheng Tung Chong (Energy)


A gas turbine-type combustor was utilised to compare the combustion characteristics of biodiesel, diesel and Jet A-1 fuels. The experiments were performed with preheated primary air of 623 K at atmospheric conditions. Due to the heating value differences between biodiesel and baseline fuels, the power output was matched to 6 kW for all fuels for comparison. Among the diagnostics applied were (i) Phase Doppler Anemometry (PDA) (ii) Chemiluminescence imaging (iii) Flame spectroscopy and (iv) Emissions performance. The result indicates that biodiesels are potential fuel candidates for gas turbines.
