Abstract
A catalytic combustor has an array of fuel injectors and air inductor elements, upstream of a catalytic member in the combustor. Each fuel injector and air inductor arrangement is associated with a discrete passageway confining the air/fuel mixture to a portion of and the catalytic member wherein the combustion of the mixture is initiated. Each fuel injector and air inductor arrangement is provided with controls to vary the fuel and air flowing into each passageway, respectively. This permits the variation of combustion intensity within the catalytic element, which in turn permits a regulatable temperature profile at the exit end of the combustor.
Claims4
A combustor arrangement including:
- a combustor shell having an upstream portion and a discharge end;
- means for delivering fuel to said upstream end of said combustor shell said means including a plurality of fuel injector elements and means for controlling the flow of fuel therethrough;
- means for delivering air to said upstream end of said combustor shell, said means including a plurality of air inductor elements and means for controlling the flow of air therethrough;
- a catalytic member disposed within said shell intermediate said upstream portion and said discharge end;
- a plurality of passageways providing confined fuel-air communication between each of said fuel injector elements and associated air inductor elements and said catalytic member, said passageways permitting delivery of various fuel-air mixtures to discrete portions of said catalytic member without intermixing thereof, the plurality of controllable fuel-air mixtures delivered to said catalytic member permitting a regulatable temperature output from each discrete portion thereof.
