摘　　要：以天津某垃圾焚烧发电厂的400 t/d往复移动炉排式城市生活垃圾焚烧炉为具体研究对象,结合垃圾热解燃烧特性,建立焚烧炉综合数学模型并进行了仿真计算。将焚烧炉总体分为5个区进行分区计算,然后对垃圾料层在运动方向上进行分层计算,共分为112层。假定在料层内温度均匀,因此在高度方向上不再进行划分。以该模型为基础建立了国内第一台城市生活垃圾焚烧炉的仿真机。计算结果与现场数据对比表明,该模型与实际对象的运行特性符合较好。A complete mathematical model was developed for a 400 t/d traveling grate municipal solid waste （MSW） incineration plant in Tianjin including the pyrolysis and combustion characteristics of the waste. The incinerator was divided into five regions with the waste on the grates divided into 112 cells along the movement direction of the grates. Temperatures in each cell were assumed to be uniform. Simulation results with the model agree well with measured data, which indicates that the model accurately reflects the actual system characteristics.
