Gas Turbine Combustor

PROBLEM TO BE SOLVED: To provide a gas turbine combustor capable of reducing NOx without increasing the size and cost of the combustor. ; SOLUTION: The combustor for burning compressed air A supplied from a compressor 1 and fuel F and supplying them to a turbine 3 includes: a main burner 21 provided at a head portion of a combustion cylinder 10 forming a combustion chamber 11; and a reheating burner 40 arranged downstream of the combustion cylinder 10 from the main burner 21 and penetrated through a peripheral wall 10b of the combustion cylinder 10. The reheating burner 40 includes: an introducing passage 50 for deflecting and introducing part of the compressed air A made to flow toward the head portion of the combustion cylinder 10, from an air passage 15 formed between the peripheral wall 10b of the combustion cylinder 10 and a housing H surrounding the peripheral wall 10b toward the radial inner side of the combustion cylinder 10; and a fuel nozzle 46 for supplying the fuel F from a plurality of fuel supply holes 44 to the compressed air A introduced to the introducing passage 50 to generate pre-mixed gas M within the introducing passage 50. ; COPYRIGHT: (C)2010,JPO&INPIT
