ABSTRACT:
This gas turbine arrangement has an at least two-stage gas turbine (1) with a main combustion chamber (10) and a compressor (5). An energy exchanger (8) which interacts with the separate combustion chamber (14) is installed upstream of the gas turbine (1). The efficiency of the gas turbine arrangement is to be increased by simple means. In order to achieve this, the separate combustion chamber (14) is designed as an afterburner chamber for a part of the gases generated in the main combustion chamber (10). In addition, means for the additional injection of a liquid or vapor medium are provided in the region of the combustion chamber (14). The volume flow in the energy exchanger (8) and hence the efficiency of the gas turbine arrangement are increased by this injection.
