摘　　要：炼油厂加热炉烟气中硫化物所引起的酸露点腐蚀,严重影响炼油装置加热炉设备的长周期安全运行。根据烟气中硫含量,采用耐腐蚀材料、合理的结构设计和工艺上燃料深度脱硫,可以延长设备的使用寿命,降低排烟温度,提高加热炉热效率。Acid dew corrosion caused by sulfid in flue gas from heating furnace in refineries could greatly influence the long—period safe running of heating furnace in refining devices.According to the sulfur content in flue gas and with the adoption of corrosion—resistance materials,reasonable structure design and deep desulfurization of fuels,the service life of the devices may be prolonged,the waste gas temperature may be decreased and the thermal efficiency of the heating furnace may be increased.
