In order to improve the desulphurization and denitrification efficiency of low-temperature flue gas in steel rolling heating furnace,en-hance the treatment effect at low cost and energy consumption,and improve the pollution of sulfur dioxide and nitrogen oxides in the atmos-phere,the desulphurization and denitrification process of low-temperature flue gas in steel rolling heating furnace is studied.The key parame-ters involved in the desulfurization and denitrification process are analyzed in detail,and the fuzzy PID is used to complete the self-tuning con-trol of the key parameters of the low-temperature flue gas desulfurization and denitrification process,the output of the best key parameters,the completion of low cost and low energy consumption,high efficiency low-temperature flue gas desulfurization and denitrification.Through the test verification,the method can effectively achieve flue gas desulfurization and denitrification,has higher treatment efficiency,and compre-hensive energy consumption and cost are lower,after application can effectively reduce the concentration of sulfur dioxide and nitrogen oxides in flue gas,enhance the effect of desulfurization and denitrification.
