I am new to the forum but have been smoking for a while. I built a fairly large( 28"wide x 22" deep x 60 " high) smoker that is heated with a propane cast burner.
I built a smoke generator so that I am able to use the smoker for hot or cold smoking. The generator hangs on the side of the smoker (see pics).
The issue I am having is the darn smoke generator won't stay lit. It keeps going out every 10-15 minutes. When I relight it, it works for a while and then dies again.
I am wondering if someone can help me figure out what is going on and why it won't stay burning.
The smoker has one air inlet in the bottom front that measures 3" x 12". The chimneys are two 3" holes in the top with short stacks with butterfly valves to control the exhaust.
The smoke comes in through the side of the smoker approximately 3" from the floor (which is below the height of the burner- Could that be one of the issues??)
The generator is 3" square steel tubing with a cap on the bottom with an air fitting for an aquarium pump. There is a igniter /air intake hole just above the base that allows air into the generator. Approximately 8" up from the bottom, I have a venturi tube going into the smoker. There is also a copper pipe with a hookup for an aquarium pump that is supposed to push smoke into the smoke chamber. There is a cap on the top of the generator to help force the smoke into the smoker. IMG_6889.jpg 2,922k .jpg file
If anyone has any thoughts or ideas on how to get the darn thing to work,it would be greatly appreciated.
