Calculation of thermal power system based on the concept of fuel and product

The calculation result of thermal economics in power plant operation is very important for appraising the quality of thermal power system design and operation.But according to the different calculation objectives,there usually appears energy balance analysis,exergy balance analysis and thermal economics analysis,three layer surface analyses.This paper,adopting A.Valero's"fuel"and"product"con cept ,sets up concept models universally used for the aforementioned various analysis.
