Definitions
- the invention relates to a method and a modified hot gas heat engine for utilization of waste heat or geothermal heat, or, generally speaking, of heat at a relatively low temperature level, in particular in an approximately up to the boiling point of water-reaching temperature range, in particular for generating electrical power.
- waste heat or geothermal heat or, generally speaking, of heat at a relatively low temperature level, in particular in an approximately up to the boiling point of water-reaching temperature range, in particular for generating electrical power.
- a hot gas heat engine operates, unlike conventional piston engines or gas or steam turbines, with remaining within the engine and not replaced gas.
- a hot gas engine is known in the form of the Stirling engine.
- the Stirling engine which always requires two pistons, has a permanently heated cylinder area and a permanently cooled cylinder area between which the working gas is moved back and forth. In the heated cylinder chamber, the working gas expands and does work, and contracts again in the cooled cylinder chamber.
- a disadvantage of the known Stirling engine that the entire, for heating the hot cylinder chamber supplied heat must be supplied through the thick cylinder wall, which indeed allows the use of any type of heat supplied to the cylinder wall, but imposes considerable inertia on the Stirling engine. This inertia is also due to the fact that the working gas is interposed between each cycle
- CONFIRMATION COPY hot cylinder space and the cold cylinder space must be moved through relatively narrow channels.
- the hot area and cold area of the Stirling engine can not be reversed. Larger amounts of energy can therefore not be implemented with the Stirling engine.
- the object of the invention is therefore to provide a method and a modified hot gas heat engine, with which considerable benefits can be implemented, and with which in particular a much more intense heat input is possible to perform mechanical work, which is used in particular for power generation.

- Heat transfer fluid heated gas cools down again due to the work and cooled cylinder walls and can be reheated when re-heat.
- the heat transfer medium must be liquid so that it separates from the in-cylinder, pressurized gas by gravity. Nevertheless, it may be possible to use wet steam in a temperature range which causes the wet steam in the course of heat dissipation to the gas located in the cylinder chamber condenses and precipitates as condensation.
- the sump for the spent heat transfer medium is of course closed and is under the pressure of the cylinder chamber.
