Abstract: PROBLEM TO BE SOLVED: To avoid a preload generating a harmful matter by preventing hot gas derived from previously performed combustion from being supplied to a catalyst stage. SOLUTION: In an operation method of a power station plant which is mainly composed of a compressor 4, a combustion unit and a turbine 12, and takes a form in which the combustion unit is composed of an adjusting stage and a combustion chamber for at least a part of combustion air, a part 13a of compressed air 13 from the compressor 4 is mixed with a fuel quantity 14a by being quided through the adjusting stage. An air-fuel mixture reaches a genarator 8, and hydrogen fractionated in the generator is introduced into the combustion chamber. The combustion chamber is composed of a starting burner 1, a catalyst stage 2 and a second combustion stage on its downstream side. An air-fuel mixture 16a fractionated in the generator 8 and another compressed air 13 reach the combustion chamber, and between plural combustion devices in this combustion chamber, interdependent combustion is generated to reduce discharge of a harmful matter in relation to high speed operation of the plant.
