Problems solved by technology

[0007] However, the common problems of existing thermal power generation equipment are: a. The temperature at the exhaust port of the turbine is relatively high, resulting in high pressure at the exhaust port, and the work conversion efficiency of the turbine is low; b. The heat displacement of the condensing device is relatively large , the waste of heat energy is large, the condensation speed through natural condensation is slow, and the active condensation method (fan air cooling or liquid pump water cooling) requires additional power consumption; c. 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%; d. Gasification heat absorption is slow, and the output power of the thermal energy machine is relatively small; e. The heat collection effect of the heat collection device is not good, and the external waste heat absorption rate is small , f. The gasification temperature of the working fluid is unstable, the condensation effect of the working fluid is not good, and the working fluid is easy to deteriorate or appear impurities
