SCR denitrification
product description
The principle of SCR denitrification
SCR technology means that under the action of the catalyst, the NOX in the flue gas is selectively reacted with the reducing agent and produces harmless nitrogen and water to achieve the purpose of removing NOX. SCR technology has high efficiency (70%-90%) and mature technology. It is the most widely used flue gas denitrification technology.
The principle of SCR chemical reaction is：
4NO+4NH3+O2→4N2+6H2O
6NO2+8NH3+O2→7N2+12H2O
