Title:
COMBUSTOR AND GAS TURBINE
Document Type and Number:
WIPO Patent Application WO/2017/170227
Kind Code:
A1
Abstract:
Provided is a combustor equipped with: a nozzle main body (16) having a shaft body (24) extending along an axial line, and swirl blades (26) that extend from the outer circumferential surface of the shaft body (24) in the radial direction with respect to the axial line, and cause a fluid flowing downstream in the axial line direction to swirl around the axial line; first fuel flow paths (41) that supply fuel to first fuel injection holes (38a) formed in the nozzle main body (16); second fuel flow paths (42) that supply fuel to second fuel injection holes (38b) formed in the nozzle main body (16) on the outside, in the radial direction, of the first fuel injection holes (38a); a first adjustment valve (43) that is provided in the first fuel flow paths (41) and that adjusts the flow rate of the fuel flowing in the first fuel flow paths (41); a temperature sensor (33) that detects the temperature downstream from the swirl blades (26); and a control device (5) that controls the first adjustment valve (43) so as to reduce the flow rate of the fuel flowing in the first fuel flow paths (41) when the temperature detected by the temperature sensor (33) satisfies a predetermined condition.
