Chimney exhaust \"branching\"?

2020-12-10View Original

Thread Content

The exhaust gases from the two rotary kilns share one chimney, and recently a noticeable phenomenon of \"splitting\" in the exhaust flow has been observed. The inner wall of the chimney has an anti-corrosion coating, and some suspect that the coating has fallen off. But this phenomenon also occurs in the chimney connected to another single boiler. Please help analyze the possible reasons.

That’s not a divergence; it’s caused by the vortices generated by the hotter rising smoke, which affect the steady spread of the smoke

I read the replies from the second floor; it was really enlightening

It’s possible that the chimney of the boiler also exhibits this phenomenon to some extent. I’ll wait for a chance to stop and take a look inside.

This phenomenon is not noticeable when the wind is particularly weak or even absent. But if the wind is too strong. This phenomenon has also been disrupted.

Are the two inner cylinders in the concrete chimney connected to the flue gases from two separate furnaces?

The smoke coming out of a flue splits into branches; it’s interesting. I hope some expert can explain this. The claim that the vortices generated by the hotter rising flue gas affect the steady diffusion of the smoke seems unconvincing – after all, in every flue, hot gas rises. I hope an expert can provide a more detailed explanation

Is it possible that the anti-corrosion coating in the middle and upper sections of the chimney could peel off and get stuck there, dividing the flue gas into two streams?

Is it certain it’s not the prostate speaking? ;P
