ABSTRACT:
A combustion apparatus for gas turbine engines employs a combustion liner structure adapted to promote complete combustion of liquid hydrocarbon fuel and minimize undesired combustion products. Compressed primary air flows radially inward with swirl into a prechamber into which fuel is sprayed. Except during start-up, the air is heated. Normally, the air mixes with and evaporates the fuel and the mixture flows through a throat into a reaction chamber. The upstream end of the reaction chamber is bounded by a conical annular wall. The liner wall downstream of the throat defines the reaction zone to which additional primary air is fed and a dilution zone to which secondary air is admitted. The area of the primary air entrance is variable to maintain a lean fuel-air ratio in the reaction zone throughout the operating regime.
