Utilisation of waste heat and increasing the power output of gas turbine plants

摘要

The arrangement (100) has a gas turbine system (110) for generating mechanical power. A heat power plant (120) comprises a heat exchanger (121) and a turbine (122). The heat exchanger is coupled with the gas turbine system such that thermal energy from the exhaust air flow (112) is transferred to a working medium (126), so that the turbine is operable by the working medium. A compressor (130) is utilized for compaction auxiliary air flow. The compressor is coupled with the gas turbine system such that compressed auxiliary air airflow (131) is fed into the gas turbine system. The heat exchanger is a plate heat exchanger, a spiral heat exchanger, a pipe heat exchanger and/or a tube bundle heat exchanger, a U-tube heat exchanger, a tube heat exchanger or a counter current layer heat exchanger. The gas turbine system is a generator (140) or a gas compressor. The compressor is a radial or axial-flow compressor or a piston compressor. An independent claim is also included for a method for operating a power-heat coupling arrangement.
