minimum velocity in a chimney
minimum velocity in a chimney
(OP)
Hi guys,
Does anyone know if there is a minimum flue velocity required by any standards for a chimney connected to a pellet stove. Following my calculation the velocity of the gas in this chimney is 0,49 m/s, that in my opinion is too low.
Infact a low flow velocity will allow particles to settle out and promote condensation of any creosote that may form.
Since I do not know any code or standard that cites the minimumu velocity for the smoke in the chimney, I would like to be helped.
Thank you in advance

But think about your criteria and your concern: Place your hand on the floor, and try to raise it all the way to the ceiling at 1/2 meter/sec! That is a "lot" of air flow. Are you not more concerned about the replacement of that much combustion air in the room with cold outside air, and the drafts inside the room as that air is moved from the walls towards the stove?

If I had access to the ASHRAE handbooks I'd be checking there, after quizzing the pellet stove manufacturers.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

You are judged not by what you know, but by what you can do.

It's a bit remiss of you not to advise that this post contains lots more info on your issue.

A lot of this should be vendor driven
