WSA waste pot blockage
Thread Content
Have any of my colleagues encountered the problem of frequent blockages in the tube banks of the waste boiler following acid gas incineration? I would appreciate guidance on the causes and solutions. Thank you
The reason is incomplete combustion of the acidic gases; it can be understood as too much carbon buildup blocking the tubes.
Have you encountered a similar problem? How to solve it?
The feeding issue is still the first thing to consider; if the feed is dirty, full combustion is of little use. Do your furnaces burn acidic gases directly, or is waste acid added? What about the size of the waste boiler? What is the size of the tube side, and how many cubic meters of feed are there per hour? And what about the operating procedures for the combustion furnace? What is the oxygen content?
Is an online dust cleaning device installed?
An online dust removal device is definitely required; however, the acid gas does not burn completely, it contains impurities and is somewhat sticky, which can easily lead to blockages.

This kind of blockage is similar to asphalt and is difficult to clean. Is your acid production high? If it’s not big, just put it in a torch.
How to set up the WSA device for online dust cleaning?
The raw material is only acid gas, at a flow rate of 5000 m3/h, with an oxygen content of 6–7%, and the temperature in the incinerator ranges from 970 to 1100 degrees℃
