The Research Of Operating Property Analysis Model Of Subcritical Pressure Boiler In Variable Conditions

This paper carries on the research of the variable condition property theory model for large-capacity power plant boiler. For the limitation of the former Soviet Union boiler unit heating calculation standard methods in 1973 in the boiler furnace,panel and platen superheater,this paper puts forward the new methods of the boiler heating calculation. In accordance with a boiler whose capacity is 1025t/h in a certain power plant,this paper builds the heating calculation model of new method and the former Soviet Union method, finds the solutions to the model under the designed coal quality, compares the results with the design data, verifies and analyzes the new heating calculation model.
