摘　　要：通过选取床温、烟气含氧量和炉膛残碳量3个参考对象,以小室模型为基础对流化床锅炉内的物料平衡、氧气体积平衡和能量平衡做数学模型描述,用Matlab对其做阶跃响应仿真,通过仿真曲线和历史趋势进行对比发现二者趋势基本一致,验证了所建循环流化床燃烧系统机理模型的准确性与合理性。In this paper, the material balance, oxygen volume balance and energy balance in the fluidized bed boiler are described with mathematical model based on the cell model with the three selected reference objects of bed temperature, flue gas oxygen content and residual carbon.The step response simulation is conducted with Matlab.By comparing the simulation curve with the historical trend, it is found that the trend is basically consistent, which verifies the accuracy and rationality of the mechanism model.
