摘　　要：针对工业有机固废非均匀燃烧导致料层局部高温的问题,设计了“风移变拱”固定床实验装置并提出模型化方法,研究了不同混烧方式工况下层状燃烧特征的差异,揭示了不同混烧方式的层状燃烧局部高温特征。通过构建包括燃料种类、掺混比和过量空气系数的局部高温表征模型,可在技术层面上为城市废弃物焚烧设施协同处理高热值工业废弃物提供分析判断手段和技术参考。Aiming at the problem of local peak temperature of the solid combustion zone caused by the non-uniform firing of industrial organic solid waste,a"wind moving and variable arch"fixed bed experimental device and modeling method were proposed to study the differences of the grate combustion characteristics under different mixed combustion modes,and identify the local peak temperature.By building a local peak temperature characterization model including fuel type,mixing ratio and excess air coefficient,it can provide analysis and judgment means and technical reference for the simultaneous disposal of higher calorific value industrial waste by municipal waste incineration facilities.
