Abstract
This paper describes the development of a 1300°C class gas turbine combustor burning coal-derived low-Btu gaseous fuels. Coal-derived gaseous fuels contain NH3 if a gas cleaning system is hot type and NH3 will be converted to NOx in the gas turbine combustion process. Combustion tests were conducted by using the newly designed, advanced rich-lean combustor. Combustion stability was excellent for the testing combustor because of a subcombustor, so combustion stability could be obtained even when the calorific value of fuel decreased to about 2600 KJ/m3N. As for NOx emission, NH3 conversion to NOx was 40% under the full load condition at 1300°C of the combustor exit gas temperature for 1000 ppmv of NH3 concentration and 0.7 vol% of CH4 in the fuel.
