FLUE GASES DUCTS: ROUND vs RECTANGULAR
FLUE GASES DUCTS: ROUND vs RECTANGULAR
(OP)
Hello,
Where can I find guidelines or can someone advise on the issue of the duct shape, in our case the cross section of the required duct is 3.25 sq.meter.
regards,
roker

RE: FLUE GASES DUCTS: ROUND vs RECTANGULAR
In a rectangular duct, it's slightly easier to fabricate a short radius bend ... not that a short radius is a good idea.
I wonder if anyone made flues rectangular before the appearance of baghouses, which tend to be rectangular for more defensible reasons.
Transitions, e.g. from rectangular baghouse apertures to round ducts, are a little harder to manufacture than simple joints. They're harder to draw, too, which may be the real reason rectangular flue ducts first appeared.

As you can see from the above, I would suggest some research on the subject. There is much more information.

Also check for guidelines from the environmental agency in your jurisdiction, like EPA (http://www.epa.gov) in the US.
