The Simulator Model for A Circulating Fluidized Bed (CFB) Boiler
首发时间:2007-06-28
Abstract:The reaction kinetics model has been widely used to simulate the CFB for training simulator in the past. This paper introduces a CSTR equilibrium model, which is stable and had been used to simulate a real 100 MW CFB boiler in power plants. The dynamic response of the simulation model matches that of real plant during start-up,normal operation, step changes, abnormal operations (process upset conditions) and shutdown. The steady state can be within ±1.0 % and dynamic accuracy within ± 5.0%.

循环流化床过程仿真的数学模型
摘要:传统的循环流化床仿真的数学模型都采用反应动力学的方法。本文采用了CSTR的平衡反应算法,对循环流化床建立仿真的数学模型,已用于100MW循环流化床的实际工业装置仿真培训器中,算法比较稳定,模拟了循环流化床的开停车、事故处理和正常操作,动态趋势和实际工业装置相符。和设计值相比,模拟的稳态误差在1%以内,动态误差在5%以内。
