摘　　要：CFB锅炉设计过程中必须有效控制尾部烟道的烟气流量偏差,从而保证锅炉运行时尾部烟道受热面壁温偏差控制在安全范围内。本文作者发现分离器出口烟道形式对烟气流量偏差影响较大,通过CFD计算的方法对烟道形式进行优化,并在某350MW-CFB锅炉机组上实践,达到了理想的效果。The flue gas flow deviation of the backpass of CFB boiler must be effectively controlled in the design process to ensure that the temperature deviation of the vessel during boiler operation is controlled within the safe range.In this paper,the author found that the outlet flue form of the separator has a great influence on the flue gas flow deviation.The flue form was optimized by CFD calculation method,and applied to a 350MW-CFB boiler unit,the ideal effect was achieved.
