摘　　要：循环流化床锅炉是一个分布参数、非线性、时变、多变量紧密耦合的对象。文中对其建立了动态数学模型 ,仿真了在参数变动下锅炉的动态特性。针对一 35t/h循环流化床锅炉进行了动态仿真计算 ,仿真了给煤量与送风量降低及突然断煤事故。Circulating fluidized bed(CFB)boiler is a distributed parameter, nonlinear, time varying and multivariate coupling system. In this paper the dynamic mathematical model of CFB boiler was established and the dynamic performance under variation of different parameters was simulated.The dynamic computation was carried out toward a 35t/h CFB boiler, in which the dynamic performance under step change of coal, step change of air, and the accident of sudden loss of coal were simulated. The results indicated that the model can reflect the dynamic performance of the boiler properly.
