| Abstract |
Geothermal energy has the potential to play an important role in the future energy supply of China. Based on mid-low-temperature geothermal resource and waste heat resource, the paper introduces the energy efficiency of single-flash and binary cycle geothermal power plant. The result shows that binary cycle plant is favorable for power generation when water temperature is below 130Ž, otherwise, flash steam power plant is a better choice. Furthermore, two project cases were analyzed in the end, focusing on the operating parameters and thermal efficiency. The two types could be improved energy efficiency of low-grade resources and both widely utilized in China. |
