Is it necessary to spray water into the flue?
Thread Content
During the shutdown for maintenance, severe damage occurred to the lining beneath the flue water spray nozzles (the flue temperature was above 690°C at the time of operation, so we activated the flue water spray system). We’re not sure if there were any issues with our procedures; we hope experts can provide some guidance!
The temperature isn’t that high either; we can add CO as an oxidizer! Why is a dilute-phase water spray used? Water spraying has a significant impact on the catalyst; our plant has not used it since it started operating
Isn’t water jetting a technology from a very long time ago?
What are the current methods to address the issue of excessive temperature in the flue gas of the oxygen-deficient regeneration reactor?
Flue water spraying and steam injection are still in use; the most important thing is to control the issue of secondary combustion, as that is key. However, cooling measures serve as a safeguard against overheating.
The water spraying at the outlet of the regenerator flue gas header is not the water spraying inside the regenerator
We still have it today – it’s the water spray at the back of the regenerator flue gas collection duct!
It’s the design institute! But we hardly use it anymore.
Does water spraying cause a lot of damage to the smoke extractor?
Spraying water is harmful to flue expansion joints; it accelerates corrosion and can also cause scaling on the fan blades, leading to a decrease in the fan’s efficiency
