Smoke stack location

[motolife313]

Going to put another 4" stack on so I can have bigger fire and cold smoke easier. If I put the stack at the bottom will that make my bottom shelf run even cooler then the top shelf or make will it run more even since it should be pulling heat in that direction I'd think? Got this piece from a company that makes semi exuast parts, I was thinking about putting it just about the bottom rack. Looking for the most even heat across the smoker.

Moto,do you plan on adding a flapper/gate on the CC at the mouth of the new pipe? Running the new into the old on the exterior?

 

[motolife313]

That's a good idea to put a gate inside if that's what u Mean. Not sure what u mean on the secound part. It would be similar to the pic

 

[motolife313]

Do you mean combine them near the end of the stack to get a stronger pull?

 

[motocrash]

Yep,that's what I meant about the gate. And yes,spice it in / have the lower pipe meet the upper in its bend to promote smooth flow.

I would put both stacks at the bottom of the CC and make a reverse flow out of it... They will need to be well insulated so they don't create a cold dam... Better yet, run them on the inside... so the smoker keep them warm... That would be the typical set up for a "gravity feed" smoker....

Dave I have no problems with slow exuast flow right now. Comes out very fast actually

 

[motolife313]

Moto I'd think that would slow down the air flow tho. A lot of work to to gamble on. Unless it's a proven theory on smokers?

1 vote for the bottom thanks Dave!

 

[motocrash]

You are correct. It would be a lot of work. I was thinking a header and exhaust scavenging.Dave's idea is solid and proven.

 

[motolife313]

I think the smoke gue in the exuast will add even more insulation to the already good stainless pipe that will hold heat much better then mild steel

I'm hoping the heat will get pulled down that way where the new exuast will be, the top rack runs about 10 degree hotter I think. Don't remember haven't checked in a while but I can feel it with my hand. I'd like to get some more oven gauges to check temps in different spots. I run 2 in it at all times. And I could get the heat really dialed in with a better diffuser plate that I got now. I was thinking a water pan before the exuast too but didn't no if it would just steam away and have water dripping out the door from steam. I wanna get it a try. Just weld some 6" -8" tubing cut 2.5-.3" tall and weld them on my diffusers I'm using now. I'm not afraid to try different things

Theoretical working of a "gravity feed" reverse flow smoker...

I've thought of that idea. It's kinda like a car window . Cleaned up the inside tonight. And the inside ain't as pretty as it used to be. First 5 minutes of firing it up it looked like this lol
