An experimental investigation was conducted on the combustor of micro gas turbine burning ethanol as a renewable biomass fuel

including 4 kinds of fuel supply modes.The ignition and lean blowout performance characteristics of this combustor under atmospheric pressure and temperature inlet condition were obtained.The research results indicate that

at atmospheric pressure and temperature

the equivalence ratios of lean ignition and lean blowout for the ethanol combustor with swirl-cup decrease with the increasing airflow rate

and the swirl-cup combustor has better ignition and lean blowout performance than the premixed prevaporized combustor.
