Combined gas=steam power unit with forced circulation steam generator

摘要

The power unit has a gas turbine circuit and a steam turbine circuit. The exhaust gases of the gas turbine (4) give up their residual heat to the steam turbine (9,10) via a working medium flowing in a forced circulation steam generator (7). The water-steam circuit is arranged for supercritical parameters. It includes a steam turbine on the same shaft as the gas turbine. The working steam produced in the low pressure part (10) of the steam turbine condenses in a condenser (11). The condensate is pumped to the steam generator.
