ABSTRACT:
A combustor for a gas turbine engine. The combustor employs an array of fuel injectors arranged across and in the mouth plane of the combustor flame tube. Each injector has a baffle plate through which the injector nozzle projects, the baffle plate having axial holes for atomization air to intercept and atomize radial fuel jets from the injector nozzle. Cooling of the flame tube is performed by full coverage impingement and effusion without disturbing the cooling film by entry and penetration of transverse air jets. Flame stabilization is achieved under all required operating conditions by the radial-fuel/axial-air atomization in conjunction with the baffle plates. Comprehensive combustion mixing and dilution is achieved by the uniformly distributed supply of up to 90% of the total air supplied to the combustor around and through the baffle plates. There is a resultant economy in the air used for cooling, a uniformity of temperature distribution, stability of operation, and minimal emission of oxides of nitrogen.
