SCR(Selective Catalytic Reduction System)
Principle of the SCR system(Reduction reaction by Urea)
|Urea is injected by the Urea injection device.The Urea is decomposed into ammonia and carbon dioxide by the heat form exhaust gas.|
|Generated ammonia,nitrogen oxides and oxygen are decomposed into nitrogen and water by the catalyst in the reactor.|
