烷基苯装置加热炉检修改造节能分析

Analysis on Energy Saving for Maintenance and Transformation of Alkyl Benzene Unit Heating Furnace

介绍了金桐石化烷基苯联合装置2021年度检修改造中加热炉的主要检修改造内容,通过计算分析了加热炉改造后对装置产生的节能效果。通过更换热管换热器、加热炉内衬修补、炉管清灰和快开风门的更换,加热炉炉效率得到了显著提升,节省了天然气用量,降低了装置能耗,产生了显著的经济效益。

This paper introduces the main contents of the heating furnace in 2021 alkyl benzene combination plant,and the energy saving effect on the device is calculated and analyzed.By replacing the heat exchanger,repairing the heating furnace lining,cleaning the furnace pipe ash and replacing the quick opening air door,the efficiency of the heating furnace has been significantly improved,saving the amount of natural gas,reducing the energy consumption of the device,and producing significant economic benefits.
