Chemical mechanism on SCR
Low temperature catalytic reduction reaction in the flue gas temperature about 160 ℃, direct injection into the furnace gas ammonia
As a reducing agent, will become a nitrogen oxides reduction with water.
The main reaction:
4NO + 4NH3 + O2 → 4N2 + 6H2O  (1)
6NO2 + 8NH3 → 7N2 + 12H2O    (2)
For most reaction equation (1) is the main reaction, the added quantity depends on the removal of ammonia nitrogen oxides and ammonia escape amount.
SCR key elements
Key 1: the temperature of the catalyst operation (150 ~ 400 ℃).
key 2: the dosage of the catalyst.
