GAS TURBINE COMBUSTOR

摘要

Provided is a gas turbine combustor capable of reducing the size of a low-temperature air layer of pilot air formed between a pilot flame and a premixed flame and of improving the flame stability of the premixed flame. A gas turbine combustor 1A, which is provided with a pilot burner 3 that is provided at the center portion of a combustor main body formed in a cylindrical shape to form a pilot flame, and a plurality of main burners 10 arranged so as to surround the outer periphery of the pilot burner 3 to form a premixed flame, includes, as the ignition improving part, a channel blocking member 20 that reduces the size of the low-temperature air layer of the pilot air formed between the pilot flame and the premixed flame.
