“The supercritical CO2 cycle is matched with coal-fired boilers in low-temperature scenarios to form efficient power generation units. The low temperature conditions in winter and spring in coal bases in northern China are conducive to building efficient units. Experts conducted thermal calculations and economic and social benefit analysis on the supercritical CO2 cycle power generation unit, and the results showed that its net power generation efficiency throughout the plant was higher than that of the secondary reheat ultra supercritical steam turbine generator unit.”
