Zusammenfassung:PURPOSE: To obtain a burner of a combustor of which the fore end part can be cooled sufficiently, in regard to a premix combustion type burner used mainly for a multiburner combustor. CONSTITUTION: A fore end part 36 of fuel introducing pipes 32 and 33 is inserted into and disposed in a combustion chamber. An air introducing passage 42 is provided in the outer periphery of the fuel introducing pipes 32 and 33 and fuel nozzles 34 jetting fuel into the air introducing passage 42 are provided. After the fuel passes through the fore end part 36 of the fuel introducing pipes 32 and 33, it is turned back to the base end side of these pipes by a fuel introducing passage 35 and introduced into the fuel nozzles 34. The fuel supplied is made to run against the inside of the fore end part 36 so that it be subjected to impingement cooling.
