gravity feed transfer tube

Post by jl170 » May 17th, 2015, 7:09 pm

Hi everyone

When designing a Texas offset reverse flow smoker there seemed to be great science around the opening sizes from firebox to cook chamber and at the end of the baffle plate.

No one seems to have the same concerns with the gravity feed cabinet and looking at builds can see a variation in size of the opening from the firebox into the cook chamber, the length of the tube, the height of the holes from the firebox grate no to mention size / shape of the firebox itself.

Question is, does the size of the transfer tube openings matter? I've not seen anyone mention this and think that as long as there is some common sense applied when keeping in mind airflow that it doesn't matter.

This is the design we've come up with in this area:

Firebox is rectangular 6" deep, 8" wide, opening will be 6" wide, 3" high, with a grid of half inch square holes.

Take no note of the frame being a little bit short in the corners at the moment...

The shadow plate and the baffle plate combo are a great way to go. I have done this on several of these that I have built. as far as the throat opening goes it depends on the size of your chute burn area and the cook chamber volume. your numbers should work fine. I do recommend a large ash box volume tho. :beer:

Well, I would have to say, take the guess work out of it and use a proven set of plans like so many others. The price is a small fee which keeps this site up and going. It also comes with tech support http://www.smokerplans.net/index.php?ma ... cts_id=167

Well I didn't see you there OB1
