Selective Reduction Method (SCR) Denitrification Device for 2X330MW

Heating Unit in Xing'an Thermal Power Plant, Inner Mongolia

Project Overview:
The flue gas denitrification technology used in this project adopts the most widely

used, mature, and effective selective reduction (SC) denitrification process. Under the

action of a honeycomb catalyst, liquid nitrogen (NH3) is used as a reducing agent to

selectively react with nitrogen oxides (NOX) in flue gas at a temperature between 310C

and 430C, generating non-toxic and pollution-free gas and water.
