Title:
COMBUSTOR FOR GAS TURBINE, AND GAS TURBINE
Document Type and Number:
Japanese Patent JP2016109309
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a combustor for a gas turbine, and the gas turbine capable of reducing NOx emission from a diffusion combustion type reheating burner.SOLUTION: A reheating burner 36 includes cylindrical fuel injection nozzles and an air hole 340. The fuel injection nozzles are supported by an outer casing 35 along eight axes 360 included on a plane orthogonal to a central axis 302, and arranged at equal intervals (45 degrees interval) in a circumferential direction. Eight fuel injection nozzles are constituted as one fuel injection nozzle row, and four fuel injection nozzle rows 38a, 38b, 38c, 38d are arranged at prescribed intervals along a direction of the central axis 302. An angular position of each fuel injection nozzle is shifted by a half pitch angle in the relative row.SELECTED DRAWING: Figure 2
