Problems solved by technology

[0007] However, the common problems of existing thermal power generation equipment are: a. The temperature requirements for high-temperature heat sources are high, generally above 200°C, and the thermal energy conversion efficiency is low. The thermal energy conversion efficiency is generally 15% to 35%. Under the heat source of ℃, the average thermal energy conversion efficiency is 18%; b. The gasification of the working fluid in the gasification device is prone to incomplete gasification, the volume expansion is small, and the amount of external work in a single cycle of the gasification process is small; c. The gasification temperature is unstable, the condensation effect of the working medium is not good, and the working medium is easy to deteriorate or appear impurities; d. The driving force of the turbine is small, and the efficiency of converting the external work of the gasification medium into mechanical energy is low; e. The speed of the turbine is unstable, and It is prone to stuck problems; f. The heat collection effect of the heat collection device is not good, and the external waste heat absorption rate is small; g. The heat displacement of the condensing device is large, and the heat energy is wasted. The condensation speed through natural condensation is slow, and the use of Active condensation mode (fan air cooling or liquid pump water cooling) requires additional power consumption

[0008] On the other hand, the thermal energy conversion efficiency of the existing internal combustion engine is about 45%, and the exhaust temperature of the internal combustion engine exhaust gas can be as high as 400°C, and there is a large energy waste in the exhaust emission.
