摘　　要：通过对裂解炉烧焦过程的计算和分析,获得如下结果:当前裂解炉烧焦程序存在较大的改进空间,焦自身反应产生的热量带来的系统温升很小,不会产生局部过热。可通过及时提高烧焦温度、增加空气流量和降低稀释蒸汽流量来提高烧焦效率,烧焦时间可从原来的24 h降低到15 h。The calculation and analysis results of decoking process in cracking furnace show that the current decoking procedure still needs to be improved.Heat produced during decoking reaction results in little temperature rise,so there is no local overheating.The decoking efficiency may be improved by promptly increasing decoking temperature,increasing air flow rate and reducing the flow rate of dilution steam,and decoking time may be shortened from 24 hours to 15 hours.

关 键 词：裂解炉 烧焦 时间
