Energy Efficiency Analysis of Ultra-Supercritical Thermal Power Plant Based on Aspen Plus Modeling
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. In addition, the control variables method is used to observe the changes in boiler efficiency, power generation efficiency, barnstorming efficiency, and CO2 emissions of the entire thermal power plant by varying the exhaust temperature, supply fan inlet temperature, and main steam temperature. 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.
