A combustor for a gas turbine includes a diffusion flame combustion zone, a catalytic combustion zone and a post-catalytic combustion zone. At start-up or low-load levels, fuel and compressor discharge air are supplied to the diffusion flame combustion zone to provide combustion products for the turbine. At mid-range operating conditions, the products of combustion from the diffusion flame combustion zone are mixed with additional hydrocarbon fuel for combustion in the presence of a catalyst in the catalytic combustion zone. Because the fuel/air mixture ...
[ What is claimed is:] [1.] A method of operating a combustor for a gas turbine under low, mid-range and high-load conditions, comprising the steps of:(i) under low load conditions, flowing fuel and air into a diffusion flame combustion zone and causing combustion of the fuel in said zone to generate combustion products for flow in a direction downstream from said diffusion flow combustion zone;(ii) under mid-range load conditions, supplying fuel to and mixing the fuel with the products of combustion flowing downstream from said diffusion flame combustio...
