3、SCR catalytic flue gas denitrification system principle

SCR catalytic flue gas denitrification systemthe 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.，the advantage is It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the SCR catalytic flue gas denitrification system technology can significantly reduce the concentration of nitrogen oxides (NOx) in flue gas and make it meet strict environmental protection emission standards. This high-efficiency denitration ability is mainly due to the promotion of the catalyst, which makes the chemical reaction between reductant and NOx more rapid and thorough.、It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency.
