I'm considering building a wood stove out of a 55 gallon barrel with a non-standard pipe design, where the stove pipe enters through the front of the barrel and runs along the top to the back. On the front, there's still a vertical section to get the smoke away from the operator's face and to create a draft.
I'm looking for some opinions on whether this design is reasonable and can be expected to work, or suggestions for a different design that accomplishes the same goal better.
Context: This is for a temporary outdoor tent sauna. The idea is to stick the back of the barrel into a tent-like enclosure (with a metal sheet "wall" around the barrel), pile up rocks on it, and splash some water. Having the pipe come out of the front avoids running it through the tent, eliminating the need to create an additional opening for the pipe and ensuring that no combustion products leak into the tent.
