Abstract (en)

[origin: EP0767290A1] A power plant comprises a gas turbine group followed by a waste heat steam generator and then a steam circuit. The gas turbine group has at least one compressor, burner, turbine and generator. In one of the heat-exchanger stages of the waste heat steam generator (15) that operates in the lower temperature regime, a water quantity of more than 100% circulates. The excess above 100% branches off at the end of this stage and is evaporated in at least one pressure stage (26). The steam (37) is passed to a turbine (17). The still hot water (36) from the pressure stage goes to a feed water reservoir and deaerator (22), whence further steam arising is passed to another turbine (18).
