Abstract

A combined gas-steam turbine power station has a gas turbine installation (1) and a steam turbine (5) connected with a generator (24). The combustion gases from the gas turbine (1) are heated in an additional firing place (2) and then flow through at least two evaporators (3, 4), the first of which has an overheater. In addition, a closed steam circuit is provided, in which the evaporator (3) with the overheater followed by the steam turbine (5) is located, as well as a heater (6) for a double-circuit heater (8) preferably provided for heating a long-distance energy medium (7). The second heater (9) of the double-circuit heater (8) is arranged in a closed heat pump circuit (10) in which the second evaporator (4), a steam compressor (12) driven by a motor (11) and a valve (13) are located. The long-distance energy medium (7) flows at first through the heater (9) in the heat pump circuit (10), then through the heater in the steam circuit. Thanks to the heating of the long-distance energy medium by the steam circuit and heat pump, more than 80 % overall efficiency is achieved. In addition, the outlet temperature of the gas turbine combustion gases is very low (90 DEG ), so that their thermal utilization coefficient is very high.
