Abstract
A cogeneration power plant and a method for operating a cogeneration power plant are provided, with a working medium being additionally cooled by a suitable heat pump between an outlet of a thermal heating device and an inlet of a power generator of the cogeneration process. The thermal power obtained in this manner is again available for heating purposes within the heat cycle.
Claims17
A cogeneration power plant, comprising:
- a heating device comprising an inlet into which a working medium flows, and an outlet out of which the working medium flows, and configured to extract heat from the working medium;
- an energy generator comprising an inlet into which the working medium flows, and an outlet out of which the working medium flows;
- a heat pump;
- and
- a circuit configured to deliver the working medium from the energy generator to the heating device, and then to split the working medium into a first flow that is delivered to the heat pump and returned to the inlet of the energy generator and a second flow that is delivered to the heat pump and returned to the inlet of the heating device;
- wherein the heat pump is configured to cool the first flow of the working medium;
- and
- wherein the heat pump is configured to heat the second flow of the working medium.
