摘　　要：介绍了延迟焦化装置加热炉在线机械清焦技术的原理、流程及操作步骤,该技术成功地应用于延迟焦化加热炉,避免了装置需停工烧焦的问题,有效地清除了炉管内壁的焦垢,保证了焦化装置长周期运行。清焦完成后,在相同条件下,使炉管表面温度平均降低129℃以上,炉膛温度下降42℃,加热炉燃料气消耗大幅度降低,装置总能耗降低0.8 kg(标油)/t原油。这是一种安全、快捷、环保的清焦技术。This paper introduces the principles,process and operating steps of the online mechanical decoking technology for the heater in delayed coking unit.This technology is applied to the heater in delayed coking unit successfully and helps avoid the shutdown of the unit for coke-burning.It helps remove the coke salt scale from the heater tubes effectively and ensure the long-period operation of the coking unit.When the decoking was finished,the surface temperature of the heater tube decreased more than 129℃ on average;the temperature in hearth declined 42℃;the consumption of fuel gas decreased greatly and the total energy consumption of the unit reduced 0.8 kg oil per ton.This is a reliable,rapid and environmental-friendly decoking technology.
