METHOD AND THERMAL ENGINE FOR UTILIZING WASTE HEAT OR GEOTHERMAL HEAT

摘要

In a thermal engine for producing an electrical current or mechanical output by actuating a piston by gas under pressure in a cylinder chamber of the thermal engine, wherein heat is applied to the gas compressed in the cylinder by injecting or spraying a heat transfer medium in the form of a hot liquid or hot condensable gas into the cylinder chamber from which the used heat transfer medium is then collected in a base region of the cylinder chamber and is drained into a collection chamber.

1. A method for operating a thermal engine for generating electricity or mechanical power, wherein a piston (2, 20) is driven by hot gas which is disposed under pressure in a cylinder chamber (11, 12, 101, 102, 103) of a cylinder (1, 10) of the thermal engine and which is heated by a heat supply from without, said method comprising the steps of supplying heat to the hot gas in the cylinder chamber by injecting or spraying a hot heat carrier medium in a liquid or wet steam-like state into the cylinder chamber and collecting the used heat carrier medium as a liquid or in the form of ice crystals in a bottom area of the cylinder chamber for transfer into a collection chamber.
