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, and the thermal energy conversion efficiency is generally 15% to 35%; b. The heat displacement of the condensing device is large, and the waste of heat energy is large. The condensation speed through the natural condensation method is slow, and the active condensation method (fan air cooling or liquid pump water cooling) requires additional power consumption; c. The turbine is prone to leakage of working fluid Problems; d. Turbine speed is unstable, and it is prone to stuck problems; e. The heat collection effect of the heat collector is not good, and the external waste heat absorption rate is small; f. The gasification temperature of the working medium is unstable, and the condensation effect of the working medium is not good , the working medium is easy to deteriorate or appear impurities; g. The existing equipment is relatively large
