Abstract
The invention relates to a combined thermal power plant for generating electrical energy with a gas turbine and a hot-air turbine. The hot-air turbine comprises a closed gas circuit for conducting process gas. Heat is transferred from the exhaust gases of the gas turbine to the process gas of the hot air-turbine via a heat exchanger.
Claims6
A thermal power plant for generating electrical energy, comprising:
- a gas turbine,
- a hot-air turbine with a closed circuit for circulating process gas repeatedly in the closed circuit, wherein the process gas is in gaseous form in the whole closed circuit,
- a first heat exchanger for transferring heat from an exhaust gas of the gas turbine to the process gas of the hot-air turbine, wherein
- the gas turbine comprises a first shaft, via which power can be transmitted from a turbine of the gas turbine to a first electrical generator, and
- the hot-air turbine comprises a second shaft, via which power can be transmitted from a turbine of the hot-air turbine to a second electrical generator.
