Fluids Energy Turbo Expo 2017

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.
