摘要
热力性能测试和计算是火电机组热经济性分析的基础,其中排汽焓的确定不容忽视。在分析比较目前各种在线和离线计算方法的基础上,介绍了利用Excel的矩阵函数,配合少量VBA代码,快速求解汽轮机排汽焓的具体方法。该方法以汽轮机及回热系统能量平衡为基础,遵循GB 8117-1987要求并参考ASME PTC6-1996规范。实例计算表明,该方法编程简单,计算快速,可满足汽轮机热力性能试验报告等的需要。
The computation of the wet exhaust enthalpy is an important point in thermodynamic properties test and calculations of steam turbine.A method based on MS Excel matrix functions with VBA encoding for the wet exhaust enthalpy solution was proposed.The method is founded on the energy equations of regenerative system and turbine,also follows GB 8117-1987 and ASME PTC6-1996.The computation result with real case indicates that the method is easy and practical.
