摘　　要：加热炉耗能占常减压装置总能耗的80%以上,其热效率的高低对装置能耗影响很大。玉门炼化总厂常减压装置对加热炉空气预热器进行了改造,热效率得到了显著提高。本文针对空气预热系统的改造方案、应用效果及运行中出现的问题和整改方案进行了分析。Energy consumption of the furnace accounts for over 80% of the total energy consumption of crude oil unit. The thermal efficiency level has a big impact on energy consumption of the device. Crude oil unit of Yumen Refinery Plant has transformed air preheater of the furnace, which significantly improves thermal efficiency. This article analyzes air preheater transformation program, application effect, issues during operation and the reform proposal.
