PROBLEM TO BE SOLVED: To facilitate starting, in a closed gas turbine plant to burn hydrogen carbide fuel and oxygen and generate high temperature steam by which a turbine is driven. SOLUTION: Low temperature steam from a compressor 1 flows in a combustion chamber 2, fuel and oxygen are burnt to produce high temperature gas to drive a turbine 3. Gas provides an exhaust heat through a heat-exchanger 4 and is returned to a low pressure compressor 1-1 to form a semiclosed cycle. Gas from the middle of the heat-exchanger 4 flows to a low pressure turbine 6 and is brought into condensate after a work. Condensate from a condenser 7 is heated by heat-exchangers 4-4, 4-3, and 4-2 to produce gas, by which a high pressure turbine 5 is driven, and the gas is returned to a cornbustion chamber 2 after the passage of it through the heat-exchanger 4. An auxiliary boiler 12 is situated on the inlet side of the compressor 1, high temperature gas generated at the combustion chamber 2 is diluted and fed to the turbine 3, whereby starting is smoothly carried out.
