Abstract:
1. A power plant, comprising a gas turbo group which includes: at least one compressor; at least one combustion chamber arranged downstream of the compressor; at least one turbine arranged downstream of the combustion chamber; a heat transfer apparatus, downstream of the first turbine, having a primary side arranged in a smoke gas path of the turbine and a secondary side arranged in a working fluid flow path for a gaseous working fluid; a smoke gas purification catalyst, arranged, in the smoke gas path of the gas turbo group within the heat transfer apparatus, downstream of a first part of the heat transfer apparatus and upstream of a second part of the heat transfer apparatus; a pressure accumulator; at least one accumulator fluid expansion tank connected to the pressure accumulator wherein the heat transfer apparatus is arranged, on the secondary side, in a fluid flow path leading from the pressure accumulator to the accumulator fluid expansion engine; at least one temperature measurement device for determining the smoke gas temperature of the catalyst inlet and/or the catalyst temperature; and a shutoff and/or throttle member arranged in the fluid flow path between the pressure accumulator and the accumulator fluid expansion engine; wherein a temperature controller is connected up with the smoke gas temperature of the catalyst inlet and/or the catalyst temperature as controlled variable and with the position of the shutoff and/or throttle member as controlling variable.
