Issues regarding the reducing agents used in SNCR denitration technology
Thread Content
The flue gas temperature ranges from 700–900°C, usually around 800°C. What is the denitration efficiency when the SNCR method is used, with urea solution as the reducing agent? I searched for some information online, and it was mentioned that the ideal temperature for SNCR denitration is around 900°C. Does a temperature below 900°C have a significant impact on the denitration efficiency? I hope an expert can help answer this, thank you!
The impact is significant; the denitration efficiency will be much lower
Thank you. In cases like this, would adding a catalyst or other additives help improve the situation?
It has almost no effect, and it also has some negative impacts on desulfurization inside the furnace
