Abstract: At present, ultra-supercritical power plant is the most advanced technology, which can achieve ultra-low pollutant emissions and greatly improve the energy efficiency of power plants. From the perspective of energy balance and exergy balance, the normal and ultra-supercritical units are compared.
Besides, the energy-saving mechanism of ultra-supercritical thermal power generation is pointed out: Ultra-supercritical units have lower exhaust temperatures, higher supply fan inlet temperatures and higher main steam temperatures.
