Hey all,
I'm working on a "stove in a bottle" design to put into a sauna. The idea is to seal the bottle such that the operations of the stove would be completely contained except for fuel and oxygen intake from an exterior room and exhaust into the chimney. Of course, in an enclosed space, like a sauna, it will be very important to ensure that gasses cannot leak into the sauna room itself. The gas bottle seems to be a good option because of the quality of the metal, and its ability to shed any water that might splash onto its surface during sauna sessions.
Initially, I planned a welded metal tube internal design, but abandoned that after Iearning about the high heat spawling that was being reported. The problem is that the ballon doesn't allow much space for a firebrick heat riser.
My question:
Can I use firebrick chimney cylinder elements for my heat riser? Here in Estonia, we have 20cm and 16cm cylinders. These are tested for withstanding chimney fires but not for sustained, repeated high temperatures. My plan is the sand a few mm off of the 16cm cylinder to allow for expansion when heated and to slide it into the 20cm cylinder. That would give an overall riser thickness of 2cm + 1.80cm with a 2mm gap between the nested tubes. Would this setup theoretically withstand the high heat and account for repeated expansion and contraction?
