Abstract
A combination power station with power/heat cogeneration. The combination power station includes at least one gas turbine driven by combustion gases from a combustion chamber and at least one steam turbine working in a water/steam circuit. The water/steam circuit converts water into steam in a first apparatus by hot combustion gases emerging from the at least one gas turbine. The steam is supplied to the at least one steam turbine. A separate heat transfer medium is arranged in a heat exchange relationship with a heat consumer and is heated in a second apparatus by thermal energy extracted from the water/steam circuit at a plurality of extraction points each having a different temperature. The combination power station includes means for selectively connecting the second apparatus to the plurality of extraction points depending upon a thermal output and an inlet temperature required by the heat consumer.
