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

摘要

A fuel injection valve is provided with a cylindrical injection valve main body in which one end is closed, and a fuel nozzle arranged on a center line of the main body and injecting a fuel. The main body has a plurality of air injection ports for injecting an air to an inner side in a tangential direction and forming a whirl flow in an inner portion in a circumferential direction of a cylinder portion of the main body, and the fuel nozzle has a fuel injection port injecting the fuel toward an inner peripheral surface of the main body.
