Catalytic combustion is an ultralow NO[sub x] combustion method, so it is expected that this method will be applied to a gas turbine combustor, However, it is difficult to develop a catalytic combustor because catalytic reliability at high temperature is still insufficient. To overcome this difficulty, the authors designed a catalytic combustor in which premixed combustion was combined. By this device, it is possible to obtain combustion gas at a combustion temperature of 1,300 C while keeping the catalytic temperature below 1,000 C. After performing preliminary tests using LPG, the authors designed two types of combustor for natural gas with a capacity equivalent to one combustor used in a 20 MW class multican-type gas turbine. Combustion tests were conducted at atmospheric pressure using natural gas. As a result, it was confirmed that a combustor in which catalytic combustor segments were arranged alternately with premixing nozzles could achieve low NO[sub x] and high combustion efficiency in the range from 1,000 C to 1,300 C of the combustor exit gas temperature.
