Flue gas online
Thread Content
Our plant is a waste incineration power plant. The NOX level in the flue gas online monitoring of our plant has suddenly become very low. The equipment was calibrated and the probe was cleaned, but it still doesn’t work. Please help analyze what could be the cause.
Congratulations, but I also hope you can find the real reason. The SO2 online analyzer in one of our units has, as a result of a recent shutdown and restart process, seen its reading drop from 300 mg/m3 to around 15 mg/m3. The municipal environmental protection agency conducted several tests and obtained the same results, but we are unable to explain why this happened. But over the years we have often said that the tray is clogged, right in an area of high efficiency. But this cannot be controlled manually.
Has the traffic decreased? Or were parameters like the range changed?
It’s good that it’s lower; that way the environmental protection agency won’t have to bother you every day. But the real cause still needs to be identified. Congratulations to you
