INJECTOR FOR TURBINE ENGINES

摘要

An injector (10) for turbine engines which includes a shaped injector core (15) fitted with an eccentric spinner inlet (21) communicating with a cylindrical, annular fuel spinner chamber (20) and a preheater or evaporator (28) for preheating and vaporizing fuel, wherein the vaporized fuel is eccentrically injected into the fuel spinner chamber to effect a spinning fuel sequence around a fuel guidance pin (22) extending through the center of the fuel spinner chamber. Compressed air from the turbine compressors flows through the primary nozzle chamber (12) of an air guidance nozzle (11) surrounding the injector core into a shaped secondary nozzle chamber (13), where the air mixes with the spinning fuel at a selected air flow angle to facilitate thorough mixing of the fuel and air as the combustible mixture is channeled into the annular turbine combustor (35).
