AIR AND FUEL MIXING INJECTOR FOR COMBUSTOR

摘要

PURPOSE: An air and fuel mixing injector for a combustor is provided to improve the fuel efficiency by efficiently mixing fuel with air within the injector with a rotary motion. CONSTITUTION: An air and fuel mixing injector for a combustor includes a first main body(1) having an air supply pipe(4) communicated with one side of the first main body and a fuel supply pipe(5) inserted into the rear end of the first main body; a second main body(2) coupled with the first main body by a flange(3) and having an injecting cap(6) and a nozzle(8) formed with an inducing part coupled with the fuel supply pipe, a mixing part mixing fuel and air, and an extension part; an air passage in the outer surface of the mixing part of the nozzle, and fuel injecting hole formed in one point of the air passage and communicated with a fuel supply path.
