在分析 50 0MW超临界压力直流锅炉机组结构和特性的基础上 ,以质量、能量、动量守恒定律为依据 ,建立了炉内传热算法和各锅内过程算法。并采用模块化的建模技术 ,建立了苏制 50 0MW超临界压力直流锅炉的实时仿真数学模型。

The authors have set up an algorithm for in furnace heat transfer and algorithms for various in boiler processes. These algorithms have been prepared on the basis of an analysis of the structure and properties of a 500 MW supercritical pressure once through boiler and in compliance with the mass, energy and momentum conservation law. In addition, by the use of a modularized model building technique, set up is a mathematical model of real time simulation for a Russian made 500 Mw supercritical pressure once through boiler. With the help of the above cited model it is possible to accurately simulate the static and dynamic characteristics of any specific boiler units.
