摘要
为克服循环流化床锅炉热力计算系统开发的难点,从过程系统的角度认识循环流化床锅炉,建立了由部件单元和流体节点组成的循环流化床锅炉过程系统模型。采用面向对象的方法构建部件单元库,能在不改变系统结构的条件下对部件单元库进行扩充。通过动态可视化搭建烟气和工质流程的方式构造锅炉模型,使系统能够不受锅炉结构、分离器类型、燃料、容量等级和几何参数的限制。最后,采用过程系统理论中的序贯模块迭代算法对热力计算模型进行求解。该热力计算系统已在多家锅炉制造企业中应用,主要参数的计算误差小于3%。
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%.
