中国石化洛阳分公司延迟焦化装置加热炉为两室四路进料，首次采用单炉室生产方案后，出现了加热炉出口处易结焦堵塞、压缩机喘振增加、机泵寿命受损、分馏塔操作难度增加和汽油、柴油质量受到影响等问题。通过采取炉管注汽、延长生焦周期、控制甩油流量以及进行轻烃回炼等应对措施，保证了装置的平稳运行，同时将原料优化至催化裂化装置处理，每月产生效益约540万元。

The heating furnace of delayed coker in SINOPEC Luoyang Co. consisted of two heating chamber with four feeding inlet. To meet the fuel and petrochemical market volatility,according to the benefit of priority,the original structure of the furnace was first changed to a single heating chamber furnace. This change caused some problems:coking at the outlet of the heating furnace was occurred, more compressor surge was happened,the pump was damaged,the operation difficulty of the fractiona-tion tower was increased and the quality of gasoline and diesel was adversely impacted. Several measures were adopted:injecting steam into furnace tube,extending the coking cycle,controlling the oil flow rate and recycling light hydrocarbon fractions,to ensure the safe and stable operation of the device. At the same time,the raw material was fed into the catalytic cracking unit. The benefit of about 5.4 million Yuan per month was obtained.
