摘　　要：对辽化乙烯装置进行腐蚀检查过程中,发现装置内2台CBL型裂解炉辐射段出口、第一急冷锅炉入口锥体蒸汽入口侧有高温氧化腐蚀迹象。该文分别从急冷锅炉入口锥体的结构、原理上分析锥体高温氧化腐蚀产生的原因,从而给出相应的防护措施。During the corrosion inspection of an ethylene plant,it was found that there was high temperature oxidation and corrosion on the steam inlet of the first quench boiler inlet cone at the outlet of radiation section of two CBL cracking furnaces.The causes were analyzed from the aspects of corrosion mechanism as well as the structure of the inlet cone in quench boiler;moreover,corresponding protective measures were put forward.
