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 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; c. The driving force of the turbine is small, and the gasification medium The efficiency of converting external work into mechanical energy is low; d. Turbine speed is unstable and prone to stuck problems; e. The heat collection effect of the heat collection device is not good, and the absorption rate of external waste heat is small; f. The heat displacement of the condensing device It is large, wastes a lot of heat energy, and 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; g. The existing equipment is large in size; f. The turbine is prone to leakage Working fluid problem
[0008] In the process of realizing the power output of existing solar energy, the photoelectric effect is first required to convert it into electrical energy, and then output power through electric equipment; at this stage, the equipment used to convert solar energy into electrical energy is mainly a photovoltaic panel. At about 5%, energy waste is serious
