3、Working principle of Denitrification of flue gas from annealing furnaces in steel plants

Denitrification of flue gas from annealing furnaces in steel plantsat runtime,Ammonia gas or other suitable reducing agent (such as urea aqueous solution) is sprayed into the flue gas upstream of the catalyst at high temperature. Under the action of catalyst, the reducing agent selectively reacts with nitrogen oxides (NOx) in flue gas to generate pollution-free nitrogen and water vapor. Because NH3 is selective, it only reacts with NOx and basically does not react with O2, so this technology is called selective catalytic reduction denitrification.，multifunctional, with functions such as Improve energy efficiency, environmental protection, Improve working conditions, Promote sustainable development and Improve energy efficiency，It is a product series that integrates Promote sustainable development, Meet the requirements of environmental protection, Improve product quality, Flue gas denitrification and environmental protection，it is widely used incoal-fired power station,iron and steel plant,coal-fired power station,cement plant,Gas power plant and other industries，The price is more affordable，modern technology。
