YIRAN specializes in the production of various types of forging furnace flue gas denitrification equipment, flue gas denitrification can effectively remove the nitrogen oxides in the forging furnace flue gas, the denitrification rate is more than 95%, up to the environmental standards. At present, the main denitrification methods are SCR and SNCR. When the reaction temperature is lower than that of SNCR when the catalyst is used in SCR, there is not much difference in the flue gas denitrification of forging furnace, but the investment of SCR flue gas denitrification is at least several times as much as that of SNCR flue gas denitrification from the aspects of construction cost and operation cost. Even more than 10 times. Denitrification can be divided into pre-combustion denitrification combustion process denitrification and post-combustion denitrification.
