3、Advantages of Low temperature catalytic denitrification equipment principle

Low temperature catalytic denitrification equipmentthe principle is simple.Catalysts are used to promote the selective catalytic reduction reaction between reducing agents (such as ammonia and urea) and NOx in flue gas. Under the action of catalyst, the reductant preferentially reacts with NOx to generate harmless nitrogen and water vapor, but hardly reacts with oxygen in flue gas. This chemical reaction is usually carried out in the temperature range of 200-450℃, and the specific reaction temperature depends on the type of catalyst selected.。

4、Low temperature catalytic denitrification equipment use

Low temperature catalytic denitrification equipmentIt has a wide range of uses, and is often used inImprove product quality,Meet the requirements of environmental protection,environmental protection,Flue gas denitrification,Promote sustainable development and so on，in the course of work,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.，is carefully developed by One-combustion energy saving combined with advanced technology。
