常减压加热炉燃烧优化控制仪表改造

Reform of Combustion Optimization Control Instrument of Atmospheric and Vacuum Heating Furnace

本公司1200万吨/年炼油项目于2014年正式投入生产运营,并产出合格油品。在生产过程中,加热炉会消耗燃料并排放污染物,而目前常减压装置加热炉的热效率仍有较大的提升空间。常减压装置2017年综合能耗10.2kg OE/t,其中加热炉燃料消耗占总能耗的78.6%,占装置能耗比例大,为提高加热炉热效率,并减少装置污染物排放,对常减压装置加热炉进行低氧燃烧控制优化改造。结合常减压加热炉燃烧优化控制系统改造,重点介绍常减压加热炉控制、CO在线监测技术、低氧燃烧控制策略组态。

The 12 million T/a refining project was put into operation in 2014, and qualified oil products were produced. In the production process, the heating furnace will consume fuel and discharge pollutants. At present, the thermal efficiency of the heating furnace in atmospheric and vacuum distillation unit still has a large space to improve. In 2017, the comprehensive energy consumption of atmospheric and vacuum distillation unit was 10.2 kgoe/T, in which the fuel consumption of heating furnace accounted for 78.6% of the total energy consumption, accounting for a large proportion of the energy consumption of the unit. In order to improve the thermal efficiency of the heating furnace and reduce the pollutant emission of the unit, the heating furnace of atmospheric and vacuum distillation unit was optimized for low oxygen combustion control. Combined with the reform of combustion optimization control system of atmospheric and vacuum heater, the control of atmospheric and vacuum heater, CO online monitoring technology and low oxygen combustion control strategy configuration are mainly introduced.
