摘要
PROBLEM TO BE SOLVED: To provide a premix combustion burner, a combustor a gas turbine that can effectively suppress NOX emission by suppressing a fuel excessively-rich region from being generated by a multi-injection hole nozzle.;SOLUTION: A premix combustion burner 11 for injecting premix fuel to a combustion chamber 20 of a combustor 2 includes: a premix chamber 17; a plurality of liquid injection holes 22 formed at an end wall 29 of the premix chamber 17 oriented to the combustion chamber 20; a plurality of air guide holes 18 that are offset from on a surface having a burner center axis O and connected to the premix chamber 17 when viewed from the combustion chamber 20; and a plurality of curved guides 25 that are provided in downstream positions of the air guide holes 18 at an inner wall surface of the premix chamber 17 and smoothly extended to the burner center axis O from the inner wall surface of the premix chamber 17.;COPYRIGHT: (C)2013,JPO&INPIT
