This subject source is from project reality, the project name is: Fire power generating set operate economic characteristic appraise method. This subject, mainly according to a job of calculating the module among them of this project, appraise to the hot economy of the angle A power plant No. 3 of sand. This text has introduced the law of thermal balance at first, circulation function law, the equivalent enthalpy lowers the law, the fire uses four kinds of methods such as analytic approach, this text carries on hot economy and analyzes what is adopted is the law of thermal balance, then to MATLAB language, matrix law has made an introduction. Finally, MATLAB carries on programming, takes the place of and enters the textbook example to carry on check-up, in confirming the foundation with accurate procedure, take the place of enter procedure sand corner data of A, go on hot economy analyze to sand load, 200MW of power plant, A of corner.
