Stack...

[swamperjmb]

How far down do you guys run your stacks into the CC? Are they flush or do they run down to the the lowest grate..

[Rev.Mike]

this has been a debate for some time, IMHO i ran mine just inside enough to get a good bead on it, ive read threads where some have doe it both ways and cant tell a difference,except for a jambo build, only thing i could think of to run it to grate level is for looks, JM2C. im sure someone else will chime in on it

I put mine flush and not over the food if it is going to be a long pipe. I say that so build up in the stack doesn't drip on the food as the cook happens.

I had mine placed just over the lower grate so the elbows are positioned over the FB rather than coming down from the top, I agree with avoiding the "drip". I've always operated with the thought that I didnt want a straight line exit of the rising smoke in the CC but rather I wanted the heated smoke to "roll" a bit as it was pulled back down before exiting the CC and hopefully encircle or flow over and around whatever I am smoking. jmtcw

OK thanks for your inputs. I am building a reverse flow with a 125 gallon D tank and was curious. I have done smaller ones before but not reverse flow. I have kicked around the center fed Idea for some time but already cut the whole on the end for the fire box... If knew how to upload a pic I would..

So if the calculator calls for a 30" length that includes whats in the chamber if he wanted to put it down to the lower grate.The 30" just using as an example.

I have been debating on my stack placement at the top or lower of my reverse flow, alot of different opinions my tank is 37.5 x 91" calls for a 8 inch stack 31" long. Thinking of putting at the top sticking down a couple inches to make a removable extension to test. What ya think and sorry for jumpin on the post.

I think the pipe extention for purposes of a test is a great idea. I would really like to see temp numbers compared with and without the extension of say something like 4 zones (top left, top right, bottom left, bottom right). To my knowledge no one has ever posted this type of data on this site. Maybe none of us own 4 therms to use as one time

my set up is hard piped out the end at the bottom or else my curiosity would have had this experiment completed a long time ago.

My build won't be completed for a couple months, I have the firebox completed and put it to the side, pulling the boat out and getting ready for winter storage and bow season is in. When completed will do the test and post.

Great Idea Solo. I wish that would work for my application but it wont. I thought about adding a warmer but have the smoke almost go full circle from the CC through the warmer. I don't know at this point, I'm still in the first stages so anything goes from this point on
