4、Working principle of SCR oxidation flue gas denitrification equipment

SCR oxidation flue gas denitrification equipmentat 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 a popular SCR oxidation flue gas denitrification equipment，The overall structural design is relatively simple，Structure consists of Catalyst supply system, control system, Flue gas mixing and distribution system, Temperature control and monitoring system, Catalyst reactor and so on，be loved by our customers.。
