Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating device for a hot gas engine that supplies electrical energy to the heat system of the hot gas engine, converts it into thermal energy, and improves thermal efficiency.

Heat gas engine is defined in this text as a device for mechanically converting thermal energy in which a gas medium circulates in a closed thermodynamic cycle and heat energy is supplied to said medium from the outside by means of a heating device. means.

As compared to internal combustion engines, hot gas engines have the advantage, inter alia, that the combustion gases are considerably cleaner, ie the combustion gases have a particularly low content of carbon monoxide and unburnt hydrocarbons. . As a result, hot gas engines are particularly suitable for use where air problems are to be minimized.

In known hot gas engines, fuel and combustion air are fed to a burner device and react there. The produced gas mixture passes successively through a first heater section, imparting thermal energy therebetween, and through at least one second heater section;
During this time, heat energy is similarly applied and then discharged.

It has been found that the exhaust gas mixture, although low in primary combustion gases, still contains small amounts of nitrogen oxides. These nitrogen oxides are harmful to health and a source of pollution.

The present invention not only solves the above-mentioned problems, but also has the following advantages.

First of all, since no combustor is used, there is no problem of harmful gases caused by the above-mentioned combustion, and there is no pollution.

Second, thermal efficiency can be increased. That is, the present invention provides a conductive heated part in a heat system of a hot gas engine,
By generating an electromagnetic induction current in the heated part, the heated part generates heat, and the resulting thermal energy heats and expands the gas in the expansion space of the engine. Because it is an induction heating method, it generates heat. Because you can concentrate on
The energy transfer rate is very high and the thermal efficiency can be increased.

Third, temperature control is easy. That is, the present invention generates heat by generating an electromagnetic induction current in a conductive heated part in the heat system of a hot gas engine, so it is possible to change the current value or frequency of a coil wound around the outside of the heated part. Or,
Temperature can be controlled. Note that by using high current and high frequency, heating can be performed rapidly and with high energy density.

In addition, in the present invention, entropy can be minimized by protecting the outside of the object to be heated in the heat system with a heat insulating material.

As mentioned above, the present invention is groundbreaking, has many advantages such as being able to easily obtain a power source as an energy source, and has an extremely wide range of applications.
