【摘要】 炉内燃烧控制不当会严重影响锅炉安全运行，通过实时的炉内温度分布可对炉内燃烧状态进行预测及控制。沿锅炉高度方向对炉膛进行区段划分，建立炉内温度计算模型，将实时的煤质数据、燃煤量和空气参数等作为模型输入量，实现模型在线计算，得到实时的炉内温度分布。以某660 MW锅炉为例选取运行工况，利用在线计算模型进行验证计算，结果表明，模型计算速度较快，计算结果准确性较高。更多还原

【Abstract】 Improper control of combustion in the furnace can have a serious impact on the safe operation of the boiler,and real-time temperature distribution in the furnace allows prediction and control of the combustion status. The furnace chamber is divided into zones along the height direction of the boiler, and a furnace temperature calculation model is established. Real-time coal quality data, coal combustion volume and air parameters are used as model inputs to realize online calculation of the model and obtain real-time furnace temperature distribution, and a 660MW boiler as an example of selected operating conditions, the use of online calculation model to verify the calculation, the results show that: the model calculation speed is faster, the calculation results are more accurate.更多还原
