FUEL INJECTION VALVE, COMBUSTOR USING THE FUEL INJECTION VALVE, AND FUEL INJECTION METHOD FOR THE FUEL INJECTION VALVE

摘要

A fuel injection valve, a combustor using the fuel injection valve, and a fuel injection method for the fuel injection valve. The fuel injection valve comprises a cylindrical injection valve body closed at its one end and a fuel injection nozzle disposed on the center axis of the injection valve body and jetting a fuel. The injection valve body comprises, circumferentially in the cylindrical part thereof, a plurality of air jetting ports for forming a swirl flow therein by jetting an air in the tangential inner direction. The fuel nozzle comprises fuel jetting ports jetting the fuel toward the inner peripheral surface of the jetting valve body.
