摘　　要：以常规热平衡方法为基础,经过严格的数学推导,首次将等效热降理论应用于外置式蒸汽冷却器机组热力系统循环吸热量计算的研究,并提出了相应的数学计算模型。经实例验证,该数学模型简捷、准确,为外置式蒸汽冷却器机组热力系统热经济性的定量计算和在线诊断奠定了基础。In this paper the authors first apply basic theory of equivalent heat drop on circulation heat calculating model for thermal system with outer steam cooler by mathematical derivation strictly. According to the calculating results of some actual examples,the present method is simple and accurate. Foundation for the quantitative calculation and diagnose on line of thermal system with outer steam cooler is established.
