Flue Gas Duct Thermal Losses
Flue Gas Duct Thermal Losses
(OP)
I am working on a large heating duct. It seems that the temperature of the air in the duct is dropping significantly in this one section of the duct. The section of the duct goes through an unheated section of a building but the duct insulated. I am looking for an equation that will tell me how much temperature should be lost in this duct over a certain length. I am trying to figure out whether there is something outside of the duct that is causing the temperature drop like air - in leakage.

And how tight are the joints, since leakage could be the problem and what does "significant" mean.
