Abstract After the implementation of DB37 2373-2018 standard on the NOx emission concentration limit of 100mg/m3 in Shandong Province, the control effect of our company's denitrification system is difficult to meet its requirements. After the original denitrification system of our company's No.1 and No.2 production lines adopted sealing plugging and denitrification measures such as replacing, repositioning the spray gun and reducing the oxygen content, the concentration and amount of NOx emission was greatly reduced, which met the requirements of the new NOx concentration emission standard, and the production cost was also saved. Only the sewage charge can save more than CNY 400 000 per year.
