ABSTRACT:
A combustor for burning heavy residual fuel to drive a gas turbine engine has an elongated, imperforate vaporizing tube with an air blast nozzle at one end of the tube adjacent a cannister type preheater means arranged to swirl air blasted residual fuel in the tube to produce vaporization while preventing autoignition and wherein the vaporized fuel is processed through a primary crossed slot air mixer means for reducing the temperature of the air/fuel mixture passing from the vaporizing tube and to establish an equivalence ratio in the air/fuel mixture at a lean reaction zone combustion chamber for burning a lean air/fuel mixture from the primary air mixer means under controlled conditions and wherein a combustor torch igniter directs an igniting flame into the lean air/fuel mixture directed from the air mixer means so as to assure continuous combustion in the lean combustion zone so as to reduce hydrocarbon and carbon monoxide emissions from the combustion apparatus under varying conditions of gas turbine engine operation.
