热力系统广义汽水分布矩阵方程及其应用

The Generalized Steam-Water Distribution Matrix Equation of Thermal System and Its Application

火电机组热力系统通用矩阵方程是电厂热力系统节能分析中一个重要的基础方程。在将锅炉过热器视为一个特殊回热加热器的基础上,对该矩阵方程进行了扩展,所提出的广义汽水分布矩阵方程较好地解决了传统汽水分布矩阵方程对同一类辅助汽水定量分析时,分析方法可能不统一的不足,是传统汽水分布矩阵方程有效的延伸和补充。最后对所述方法通过实例进行了验证。

The steam-water distribution matrix equation of thermal system is an important equation in quantitative analysis of steam turbine. Based on the foundation of superheater been regarded as a special heater, the paper extends its application range, and constructs the generalized steam-water distribution matrix equation, which solve the shortage of applying different analysis rule to analyze the same type auxiliary steam-water. It＇s an effective complementary means to its traditional form. An example is given to illustrate validity of the method.
