Abstract
A combustor for a gas turbine utilizing a catalytic combustion system comprises a cylindrical outer casing, a combustion cylinder concentrically disposed inside the outer casing with an annular space between an outer periphery of the combustion cylinder and an inner periphery of the outer casing as a combustion air supply passage, the combustion cylinder having one end facing the closed one end of the casing with a space therebetween, and a catalyst unit disposed inside the combustion cylinder, the air for combustion being supplied to the catalyst unit. A heat exchanging device is formed in the air supply passage for heating the combustion air passing the air supply passage to a temperature more than a catalytic combustion starting temperature through a heat exchanging operation by a thermal energy of a combustion gas in the combustion cylinder. The combustion cylinder includes at least one section chamber for combustion and the catalyst unit is disposed in the section chamber and includes a plurality of catalyst sections sectioned in a plane normal to a flow direction of the air for combustion introduced into the combustion cylinder. The combustion cylinder is provided with a plur…
