1、Brief introduction of External denitration system

External denitration systemthat is, selective catalytic reduction technology is a technology used to reduce the emission of nitrogen oxides in flue gas.，the 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.，it is an ideal choice for customers to buy External denitration system。
