Abstract: To deal with the difficulty in Circulating Fluidized Bed (CFB) boiler thermal calculation system development and to understand CFB boiler from the viewpoint of process system, CFB boiler process system model which was composed of part element and fluid node was constructed. The part element library was constructed by object-oriented method and could be extended without changing the system structure. The boiler model was constructed with the dynamical visualization method of constructing the fluent flow. This system was not restrained by boiler structure, separator type, fuel, capacity and geometric parameter. Finaly, the thermal calculation model was solved with sequential modular iterative algorithm in process system theory. This system was put into practice, whose calculation error of main parameter was less than 3%.
