The article covers the full research on such aspects as mathematic description, numerical analysis method and their practical applications. The diphase heating surface is divided into a hot water section, a evaporation section and a micro overheat section , the problems of model switching are avoided successfully between subcritical and supercritical working condition in the model of The diphase heating surface, and the model can be used for between subcritical and supercritical working condition without causing the model stiff infinity prick up problem. The mathematical model and dynamic characteristic account is unified and predigested for the diphase heating surface of once—through boiler under subcritical and supercritical pressure, and propose that the working conditions at phase change point could be used as divide criterion between water region and steam region under supercritical pressure, the problems are solved successfully between water and steam phase change point under supercritical pressure.

本文在过程的数学描述、数值分析以及实际应用等方面进行了系统的研究分析，将双相受热面统一划分为热水段、蒸发段和微过热段三段，所建立的双相受热面模型不但成功地避免了超临界工况与亚临界工况间的模型切换，而且消除了由区段划分欠妥所引起的模型刚性无限加剧的问题，统一并简化了超临界及亚临界压力下直流锅炉双相区段的数学模型和动态特性计算，而且提出了利用相变点工况作为超临界压力下划分汽水区域的标准，解决了超临界压力下水与蒸汽的相变点问题。

The technical schemes of the study are as follows: first, generally investigate the present using status and collect relevant technical information; next, combing the special technical request of stokehold, make a new structure arrangement on the basis of the original one; Then, make mechanical and conditional analysis to the main part of the structure; after that, make another analysis for the reliability of the original stokehold; finally, offer a reasonable plan for rebuilding and reinforcement and propose some rationalization advice.

研究的技术路线如下：首先，全面调查锅炉房现有的使用情况，收集相关的技术资料；其次，结合锅炉房的特殊工艺要求，在原有锅炉间结构布置的基础上进行新的结构布置，然后对结构主体进行力学分析和状态分析；再次，对原有锅炉房进行可靠性分析；最后，研究制定出切实可行的改造加固方案并给出合理化建议。
