With the increasing attention of Chinese government on the protection of environment and prevention of air pollution,how to achieve the ultra-low emission of boiler flue gas has become an imminent issue for the development of chemical enterprises.This paper reviews and analyzes the problem of abnormal increase in flue gas pressure during the late period of operation of waste heat boilers and desulfurization,denitrification,and dust removal devices,which leads to the inability to ensure safety production and environmental protection.The root cause of the problem is identified during the shutdown and maintenance period.Through reasonable and effective technological transformation measures and optimization of later operation plans,the dual goals of environmental protection and energy conservation and emission reduction have been achieved.
