摘　　要：通过对延迟焦化加热炉原设计和现场操作数据的核算找出加热炉存在的问题,在不对设备本体做较大改动的情况下,通过改造盘管的布置提高加热炉操作负荷,以满足焦化装置扩能的需要。并通过对燃烧器、预热器、衬里的改造,使炉管受热均匀,减少结焦,降低排烟温度,减少散热损失,提高焦化炉的热效率,达到节能减排的效果。Finding delayed coking heater＇s problems by calculating of design data and operating data, to improve heater＇s capacity only by changing the layout of coils, but not heater＇s steel structure. And through the transformation of the burner, preheater, lining, heat the furnace radiant tube evenly, reduce exhaust temperature, reduce heat loss, improve the thermal efficiency of coking furnace, to achieve energy-saving and emission reduction effect.
