Document Type and Number:
WIPO Patent Application WO/2015/178389
Kind Code:
A1
Abstract:
Provided are a combustor replacement method and a gas turbine plant with which a combustor can be efficiently replaced using existing facilities. The combustor replacement method has: a step (S14) in which a first combustor (212) having a plurality of nozzle systems (221, 222) that are each connected to one of a plurality of fuel supply systems (64, 66) and are supplied with fuel from the connected fuel supply systems (64, 66) is disconnected from the fuel supply systems (64, 66) and detached from the gas turbine plant (202); a step (S18) in which a second combustor (12) having fewer nozzle systems (112) than the first combustor (212) is attached to the gas turbine plant (202); and a step (S20 or S24) in which the fuel supply systems (76, 86 or 64, 66) that are connected to the same nozzle system (112) of the second combustor (12) are coupled by a coupling pipe (104 or 102), and the fuel supply systems (76, 86 or 64, 66) and the second combustor (12) are coupled.
