An injector for turbine engines which includes a shaped injector core fitted with an eccentric spinner inlet communicating with a cylindrical, annular fuel spinner chamber and a preheater or evaporator 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 extending through the center of the fuel spinner chamber. Compressed air from the turbine compressors flows through the primary nozzle of an air guidance nozzle surrounding the injector core into a shaped secondary nozzle, 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. The unique spinning component applied to the preheated, vaporized fuel and manner of introducing the compressed air into the spinning fuel using multiple, spaced injectors and corresponding air guidance nozzles effects exceptionally good air-fuel mixing and facilitates increased turbine operating efficiency and reduction of NOX emissions in the turbine exhaust gases.
