超(超)临界锅炉技术是目前世界上清洁煤发电技术的主要发展方向，性能分析计算是大型电站锅炉设计和优化运行的基础。文中研究采用流体网络理论中的“节点”和“支路”概念描述锅炉热力系统，将换热部件视为“节点”，部件之间的连接视为“支路”，并用图论中的关联矩阵对锅炉热力系统的拓扑结构进行描述和表达，通过建立各节点的质量守恒、动量守恒、能量守恒及换热方程和热平衡方程，建立锅炉热力系统稳态性能计算的一般数学模型。从软件层面介绍基于浏览器和服务器的这种瘦客户端模式的超临界电站锅炉性能分析系统的软件架构和实现方法。通过一台超临界锅炉改造工程的性能计算，验证了文中模型和方法的有效性。

Supercritical and ultra-supercritical boilers are the main development directions of the world’s clean coal power generation technology. Performance analysis and calculation are the basis of the design and optimal operation of utility boilers. This paper used the"node"and"branch"concept of the fluid network theory to describe the boiler thermal system. Heat transfer parts were abstract to nodes and the connections between these parts were abstract to branches. The incidence matrix in graph theory was adopted to describe and express the connection relation of the boiler thermal system. The nodes follow the laws of mass conservation, momentum conservation, energy conservation, as well as the equations of heat transfer and heat balance. According to these laws and equations, a general mathematical model to calculate the steady state performance of the boiler thermal system was built. The performance analysis platform of supercritical boilers was based on browser and server which belong to the thin client. The software architecture and implementation of this platform were introduced. Thermal performance of a supercritical boiler reformed was calculated and analyzed. The results verify the validity of the model and method.
