The denitrification system is limited by the flue gas temperature condition and cannot operate normally when the flue gas temperature is low.To address this issue,an SCR(Selective Catalytic Reduction)flue gas denitrification system was installed between the boiler economizer and the air preheater.In order to ensure that the flue gas temperature at the denitrification inlet met the activity range of the selected SCR catalyst,the boiler was optimized and redesigned with a high-temperature flue gas bypass for denitrification.Considering the operational conditions,in order to ensure the effectiveness of the transformation,adjustments tests were made to the air and flue gas system when the boiler was operating at low load.The goal was to achieve emission standard of the SCR flue gas denitrification system.
