Product Description
Working principle of SCR System
4NH3 + 4NO + O2→ 4N2 + 6H2O
8NH3 + 6NO2→7N2 + 12H2O
2NH3 + NO + NO2→2N2 + 3H2O
The ammonia needed for the SCR reaction comes from the hydrolysis of a urea solution:
CO(NH2)2 + H2O CO2+ 2NH3
COMPLETE SCR SYSTEM WORKING
The SCR system adopts an injection system with compressed air assistance. The urea solution supply pump is equipped with a built-in control device, which can control the internal urea solution supply pump and compressed air solenoid valve to operate according to established procedures.
