Flue gas treatment technology: flue gas denitrification Denitrification treatment of coal-fired flue gas can be understood as a reversible reaction through the action of metal catalysts, which significantly improves the conversion rate of the forward reaction. Therefore, it is very important to ensure that the flue gas temperature is within the effective temperature window of the catalyst, otherwise the reaction conversion rate will decrease significantly. Since the temperature of the flue gas just discharged from the boiler is the most suitable, according to whether the flue gas enters the catalytic reactor after the dust removal device, the arrangement of the catalytic reactor can be divided into high dust arrangement and low dust arrangement, of which high dust arrangement is the mainstream way.
