Problems solved by technology

[0002] At present, the use of geothermal energy and waste heat in chemical plants, cement plants, steel plants, thermal power plants, and nuclear power plants is mostly for central heating of residential buildings, and the use of waste heat micro-turbines in the circulation of low-temperature working fluids to generate electricity, but the heat recovery efficiency is not high. high

The efficiency of photovoltaic power generation is only 15%-23%, and the heat loss is serious! Photovoltaic power generation costs are high! Photothermal power generation mainly includes ordinary solar Stirling engines. Due to the small temperature difference in the cycle, the efficiency is not high. The high-temperature Stirling engines require concentrating arrays and tracking collectors, requiring maintenance such as anti-wind, sand, snow, and dust cleaning, and equipment costs. high! There is also a screw turbine with solar low-temperature working medium circulation. Since the working medium circulation process must compress and condense the working medium steam, the compression and condensation alone consumes 35%-50% of the utilization efficiency of solar energy. At the same time, the circulation system is a sealed system. The cost is extremely high! High breakdown maintenance cost

Photothermal steam turbine power generation requires high steam parameters, especially high temperature requirements, which requires a concentrating tracking collector, which is expensive! In recent years, many scholars have paid attention to the power generation of solar thermal bright supporting wheel, but the output speed and torque are very small.
