摘　　要：管式加热炉是石化装置中的关键设备之一,其盘管内流动介质多为易燃易爆的烃类,承受高温高压和腐蚀的炉管通常选材等级较高,投资占比较大。如何提高管材利用率,实现更经济高效的设计,一直是加热炉设计重点关注的方向。文章采用案例对比分析方法,通过对管式加热炉对流段结构进行优化设计探讨,验证了提高对流盘管利用率的效果,并提供了对流段结构的具体改进设计方案,可为降低管式加热炉投资、推进工业炉设计水平的提高提供借鉴和参考。Tube furnace is one of the key equipment in petrochemical plants and the flow medium inside the tube is mostly flammable and explosive hydrocarbon fluids.The furnace tubes withstand high temperature,high pressure and corrosion,so the selection of materialis usually of higher grade with a relatively large investment proportion.Therefore,how to improve the utilization rate of furnace tubes and achieve more economical and efficient design has always been a key direction in furnace design.Adopting case comparative analysis method,this paper explores the optimization design of convection section structure of tube furnace.It verifies the effectiveness of improving the utilization rate of convection coils and provides specific improvement design plans for the convection section.This provides reference for reducing the investment in tube furnace and improving industrial furnace design.
