Q1: What is Subcritical、Supercritical、Ultra-supercritical steam generator？
The physical properties of water are only different from “supercritical” and “subcritical”, and " Supercritical" and " Ultra-supercritical" are a classification of the industry. "Ultra-supercritical" units have different definitions in the industry. The industry generally defines units with a main steam pressure above 24.1 MPa or a main steam temperature and a reheated steam temperature above 566 ° C as "ultra-supercritical" units.
Q2: What is MPa？
The megapascal (MPa) is a unit of measurement of pressure.
1 MPa ＝ 9.869 atm ＝ 10.197 Kg/cm2
Q3: What is Thermal efficiency？
The thermal efficiency of thermal power station is defined as saleable energy produced as a percent of the heating value of the fuel consumed.
Q4: What is heat rate？
Heat rate is one measure of the efficiency of electrical generators/power plants that convert a fuel into heat and into electricity. The heat rate is the amount of energy used by an electrical generator/power plant to generate one kilowatthour (kWh) of electricity. 1 MWh = 3600 MJ
