Advice needed: Double barrel smoker piping

[hakamo0o]

Hi all,

I have been trouble shooting my double barrel smoker for the last 3 weekends. My issue is that the temperature in the cooking chamber does not exceed 188 F.

My firebox air intake is 2"

The connection between the two chambers is a single 5" duct

The exhaust pipe is 2" (I think I should add another 2" pipe)

Am I doing the sizing right? Does anyone have a working double barrel smoker and can provide the sizes of the pipes he/she has?

Thank you

add at least another 5" duct... not enough flow... triple your exhausts... your smoker is choking

I have added another 5" duct and increased the size of the exhaust to 5" too. I'm now facing some smoke leaks and cold air ingress; so I will be using RTV silicon a lot this weekend.
