摘要:: 摘要：通过对某炼油厂常减压蒸馏装置常压炉、减压炉进行一系列能效提升改造，主要包括：

空气预热器改造；加热炉衬里改造；防爆门、看火门、弯头箱门更换。有效提高了加热炉热效

率，降低了排烟温度和炉体表面温度，达到预期的节能效果。节省生产成本49.8×104元/a，总

投资收益率23.75%，具有较好的经济效益。

Abstract: Series of energy efficiency improvementand transformation of the atmospheric furnace and vacuum furnace of an

atmospheric and vacuum distillation unit of a refinery had been conducted, mainly including the transformation of air preheater,

reheating furnace lining andreplacement of explosion-proof door, fire door, elbow box door to effectively improve the heat efficiency

of the heating furnace, reducethe exhaust temperature and the surface temperature of the furnace, obtain the expected energy saving

effect with saving the production cost to 498,000 yuan/a and achieving the total investment return rate to 23.75%, and have a good

economic benefit.
