ABSTRACT:
The present invention relates to gas turbine systems for generating high-temperature process heat. To simplify the primary circuit and to eliminate the necessity of using the same circulation means for the primary and drive circuits in gas turbine systems, a system of this type is designed so that the medium heated in the secondary part of a heat exchanger is divided into a portion of drive gas for operating the drive circuit and a portion of process gas for the actual generation of process heat in the secondary circuit. After the process heat has been given off in a process-heat consumer part, the process gas is then expanded in an expansion turbine and thereafter recycled to the drive circuit. Thereupon, the combined drive gas and process gas, which is compressed in at least one compressor located in the drive circuit, is preheated in a recuperator. The expansion turbine drives, in addition to at least one process-gas compressor, a generator, the electrical energy of the generator being used to operate a recycle blower in the primary circuit.
