The lean premixed combustion technique may be the most promising one to meet severe regulations on NO_x emission of gas turbine power plants, which has a possibility to reduce NO_x emission without lowering efficiency, and several developments of the premixed type combustor have been performed and the capability of low NO_x exhaust emission has been verified. To obtain fundamental and detailed data of lean premixed combustion technique, a systematic experimental work with a model combustor was conducted. Emission character-istics and combustion stability were examined through wide operating ranges of equivalence ratio, inlet air temperature and combustion 10ad. Exhaust pollutant emissions are sufficiently 10w when the combustor is operated at a low equivalence ratio, but only NO_x emission increases with the inlet air temperature while increasing rate with the temperature rise is not so obvious in a lean condition near the blow-off limit.
