FUEL INJECTION MEMBER, BURNER, PREMIXING NOZZLE OF COMBUSTOR, COMBUSTOR, GAS TURBINE AND JET ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a fuel injection member which reduces emission of NOx generated through combustion. SOLUTION: A fuel combustion member 20 comprises a fuel injection member body 23, which is disposed being protruded in the radial direction into an airflow from a main fuel supply pipe 17, located along the airflow, at substantially the central portion of a channel, and formed with a hollow 22 communicating with the pipe 17, and comprises a fuel injection hole 21 formed in the body 23, passing through the hollow 22. A rear edge 23a of the body 23 with respect to the airflow direction, has a thickness (t) of 5 mm or less.
