基于等效焓降法热电联产机组变工况计算

由于热电联产机组变工况计算比较少,并且由常规热量法和循环函数法等算变工况程序比较复杂,为了能比较直接方便地计算出供热机组的变工况,用等效焓降法对供热机组变工况进行编程,通过在Excel中编程迭代,能够直接准确地计算出不同变工况下的热电联产机组功率、热耗率和汽耗率等热经济性指标,简便了供热机组变工况计算,也为供热机组变工况计算提供了一种准确便利的程序。

Variable Condition Calculation Of Cogeneration Units Based on Equivalent Enthalpy Drop Method

Due to the fact that variable condition calculation of cogeneration units is relatively rare and the variable condition calculation procedures from conventional heat method and cycle function method are more complicated,in order to be more direct and convenient to calculate the variable condition of cogeneration units,programme for cogeneration units with equivalent enthalpy drop method through the Excel programming and iteration,can directly and accurately calculate power,heat consumption,the steam consumption rate and other thermal economy from the different variable conditions of cogeneration units,providing an accurate and convenient program for variable condition calculation of the heating units.
