Suitable lubricant additives were found to improve methanol's lubricity to equal that of aviation kerosene, with as little as 1% additive. The lower heating value of methanol required modifications to the WVU gas turbine's fuel system and atomizer, to provide higher flow rate of fuel then required with aviation kerosene. The gas turbine was modified and operated on methanol for an extended period, without failure. Exhaust gas emissions were tested for carbon monoxide (CO), carbon dioxide (CO2), oxides of nitrogen (NOx), total hydrocarbons (HC), and particulate matter (PM). During operation on methanol significant reductions in NOx and HC emissions were observed. Without significant change in turbine inlet temperature, this observation can only be explained by a significant reduction in primary combustion zone peak temperature. Combustion completion with methanol must then extend into the secondary dilution air zone. Start-up at idle and even at low bleed air power levels, proved to be impossible on methanol.
