Good day all. Need some assistance with FB/CC throat measurements of a Center Feed Reverse Flow Smoker design that I’m busy with. I’m using 2 donated tanks for the CC and FB so I’m working with what I have. The CC dimensions are 16.14in (dia) x 41in (L) = 36.31gal and the FB is 18.9in (dia) x 23.62in (L) = 28.68gal. I know the FB tank is a bit over sized but I’m looking to make this work with what I have.
The design I’m going with is a directly below center feed FB with the FB being perpendicular(cross and centered) directly below to the CC. The CC will sit directly on top of the FB with no spaces in between, only the throat openings in both tanks. The door of the CC and FB will be facing the same direction.
My FB throat opening to the CC according to online smoker calculation websites should be in the range between 7in to 8.22in dia round hole. I’ll be using a heat deflector plate in the bottom of the CC with openings at each end of the CC to create the reverse flow. A 4in chimney stack pipe will be center on the side of the CC (opposite the door) set at main grid height.
The issue I’m having is with the FB to CC opening/throat size. Will a 7in hole be enough to let the right amount of heat and smoke through to the CC? Seeing that the design is a center feed, I don’t want to go too big with the throat size fearing that I might get too much heat in the CC.
I could not get any info on calculations that covers center feed smokers. All of the calculations seem to address offset FB designs?
I've followed the calculations on this thread but it is also based on a standard reverse flow design
