Hi everyone! Ive built a 48x48x72 tall cedar smokehouse (will get some pictures when I get home) And I'm wondering about the intake size of my fire box and the exhaust size of the smokehouse. Here's what I'm doing for a firebox I'm building a 24in tall 24in diameter stainless firebox which will have a 2in jacket all the way around it. I'm gonna run a 6in stainless pipe from the firebox to the smokehouse and instead of stopping the pipe right at the wall I'm gonna run it to the other side and cap it off. The reason I'm thinking of doing this is I will drill 1in holes on opposite sides of the pipe probably 6 on each side for the hope that it will heat more evenly. Kinda work like a propane grill burner. The smokehouse is on a concrete slab and I have three courses of block that the smokehouse will sit on. I have no chimney yet but I'm not sure I need one with all the gaps in the cedar I have. Nothing huge but could be some up to 1/8in My biggest question is how much airflow I need on the intake of the firebox? I'm gonna take stainless bar grating and raise it 6in off the floor in the firebox so I can get plenty of air under the fire. I will be putting in I'm guessing 4 two inch ports with dampers on the sides under what will hold my wood but I'm not sure. Any suggestions would be greatly appreciated.
