PROBLEM TO BE SOLVED: To provide a gas turbine device to facilitate the execution of a turbine washing work without the occurrence of any risk. SOLUTION: This gas turbine device comprises a mixture fluid producer 5 to produce mixture fluid of a particular substance and high pressure air; and a plurality of injection nozzles 9 arranged in an annular shape in a spot situated upper stream from a turbine blade. Mixture fluid produced by the mixture fluid producer is injected through the nozzles and a turbine blade surface is washed through impact collision of the mixture fluid against the turbine blade. In a so formed gas turbine device, the mixture fluid producer 5 and a plurality of injection nozzles 9 are intercoupled through a piping, and mixture fluid switching means 20-28 to feed mixture fluid from the mixture fluid producer alternately to a plurality of the injection nozzles are arranged in the middle of the piping.
