PROBLEM TO BE SOLVED: To provide a cleaning method and cleaning device capable of easily cleaning a whole compressor. SOLUTION: A temporary cleaning water injection nozzle 6a and a temporary cleaning water injection pipe 6b are provided through an air bleed slit 5a provided in a casing 5 of the compressor 2 and the temporary cleaning water injection nozzle 6a is provided to face against a rotor blade 3 and cleaning water is injected from the temporary cleaning water injection nozzle 6a. Cleaning water is also injected from a cleaning water injection nozzle provided at an inlet casing of the compressor. With this structure, as the cleaning water is injected to an inner part of the compressor 2 respectively from a front stage and a rear stage of the compressor 2, it is possible to effectively cleaning the rotor blade 3 and a stationary blade 4. Hence, it is possible to suppress lowering of efficiency of the compressor and heat efficiency of a gas turbine. COPYRIGHT: (C)2008,JPO&INPIT
