摘要
以某发电厂的400 t/d往复移动式炉排垃圾焚烧炉为对象,采用燃烧室三维辐射传热的Monte-Carlo法对炉内的温度分布和各壁面上的热流分布进行求解。并将计算结果与实际运行数据进行了对比,二者十分符合。分析了能束中心点发射和随机点发射模型的温度分布。计算表明:采用中心点发射模型会使温度偏高15℃左右,不同的烟气吸收系数K对计算结果没有显著的影响。
Taking a 400 t/d MSW（Municipal Solid Waste） traveling grate plant of incineration in Tianjin as study object, three-dimensional Monte-Carlo method is used to study temperature and wall flux distribution in this MSW incinerator. The calculating results are compared with operating data. The comparison indicates that the model can predicate temperature field in incinerator chamber adequately. Moreover, two different emission models, central-point and randompoint model, are calculated respectively, the results reveal that the temperature obtained from central-point model is higher about 15℃ than random-point model. The gas absorption coefficient K has no distinct affect through the results used different K. Figs 8, table 1 and refs 4.
