ABSTRACT:
An object of the present invention is to transfer all of the exhaust heat from the topping gas turbine cycle and thereby improve the overall efficiency (i.e., the efficiency of the topping cycle plus bottoming cycle).
The present invention provides a hydrogen-oxygen burning turbine plant which comprises a closed-loop gas turbine cycle including a compressor 2, a hydrogen-oxygen combustor 21 and a turbine 3 and constituting a topping cycle, an exhaust gas boiler (or heat exchanger) 5 installed between the turbine outlet and the compressor inlet of this gas turbine cycle, and a bottoming cycle including an expansion turbine 6, a hydrogen-oxygen combustor 8, a condensing turbine 9 and a steam condenser 11, all of the exhaust heat from the gas turbine cycle being transferred to the bottoming cycle by means of the exhaust gas boiler, the steam that is the combustion product of the gas turbine cycle being extracted from the system at the inlet or outlet of the exhaust gas boiler 5 and conducted to a condensing turbine 22 or 9.
