1、.气化炉结构设计及制造工艺摘要煤炭资源在我国一次能源中占70%以上，所以为了适应我国缺油、少气、富煤的基本国情，本设计针对水煤浆制取合成气的大型设备——气化炉进行研究，根据一开始所选择的炉型，对其主要零部件设计计算，包括上下封头、筒体、支座、密封和人孔等结构，并绘制出气化炉的装配草图。然后对整个气化炉制造过程及以上各零部件的制造工艺研究分析，阐述关键制造工序并提出解决制造难点的方案。结合设备制造的过程经验，针对SA387Gr11CL2材料表面堆焊耐蚀层、复合钢板对接、各零部件组焊等焊接工艺也做了重点分析，并做出总结。通过查阅相关资料，最
2、终选择合适的热处理方式，即分部件单个热处理并辅助加工手段逐层消除保证后，做最后的整体消除应力热处理以达到最终效果。同时，由于设备的大型化，难以运输，所以本文对设备的现场组装、压力试验等也做了一定的介绍。关键词：德士古气化炉，结构设计，制造工艺，焊接...StructureDesignandManufacturingProcessofGasifierABSTRACTCoalresourcesaccountedformorethan70%inChina'sprimaryenergy,inordertoadapttoChina'sbasicn
