This paper describes the development of a 1300℃ class gas turbine combustor burning coal-derived low-Btu gaseous fuels. Coal-derived gaseous fuels contain NH_3 if a gas cleaning system is hot type and NH_3 will be converted to NO_x 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 2 600 KJ/m^3N. As for NO_x emission, NH_3 conversion to NO_x was 40% under the full load condition at 1300℃ of the combustor exit gas temperature for 1000ppmv of NH_3 concentration and 0.7vol% of CH_4 in the fuel.
