METHANOL, ETHANOL AND JET FUEL EMISSIONS COMPARISON FROM A SMALL GAS TURBINE

No unusual fuel system hardware problems were encountered during 15 hours of testing with methanol and one hour of testing with ethanol in a 60 hp gas turbine engine which was converted to operate on both alcohol fuels. Model predictions of low NOx (nitrogen oxides) and CO (carbon monoxide) emissions were closely approximated after installation of an air atomizing fuel nozzle. Substantial NOx reductions resulted with ethanol. Unburned hydrocarbon (HC) fuel emissions increased with methanol and ethanol. Agreement was found with five previously reported methanol gas turbine experiments which indicated from 60% to 80% NOx reductions in comparison with distillate-type fuels. Combustor inlet temperature variation was one cause of CO emission variability with methanol. Droplet size increases and increased ignition delay adversely affected methanol's CO and HC emissions.
