Abstract:

PROBLEM TO BE SOLVED: To improve reliability of a sub-nozzle air supply system which supplies pressurized air to a sub-nozzle of a dual burner of a gas turbine. SOLUTION: This power generation system 10 has a gas turbine power generation device 16 which adopts fuel gas generated in a gasifying oven 12 as main fuel, an air separation device 18 which generates oxidizing agent and nitrogen gas, an oxidizing agent booster 22 which boosts the oxidizing agent and supplies it to the gasifying oven, and a nitrogen gas booster 24 which boosts the nitrogen gas and supplies it to the gasifying oven. In such a power generation system 10, a sub-nozzle air supply system 20 is arranged for supplying pressurized air to a sub-nozzle, which is adopted to one of promotion of atomization of starting liquefied fuel, cooling the sub-nozzle after starting, and purging the sub-nozzle. The air boosted by a compressor 15a of the gas turbine power generation device 16, or gas derived therefrom, can be supplied to the sub-nozzle air supply system 20.
