I'm thinking out loud here, and would appreciate some feedback on where my brain is going. I've got this cheap old cast iron propane burner, and am contemplating what would be required to incorporate it as a propane stove for hot tenting. I'm picturing this burner in a small steel box, ideally an ammo box. 3" hole out the top for a vent pipe. Here's a pic from last year when I tried to sell it on Craigslist.
The standard against which to compare is the Nuway propane stove. My burner appears to be the same design as a 15,000 BTU burner available from Sports Authority, so the Nuway model to compare to is the 3000, which has a 16,000 burner. That retails for $149.95 plus shipping, so if I can't make my own for less than that then I don't think I'll bother.
There's a replacement gas valve on Amazon designed for gas log fireplaces (link here). If I can scrounge up miscellaneous mounting hardware I think I can make this work. There would be a standing pilot light that would be turned on when the stove is set up in the tent. The ignitor is a nice touch for that. When heat is desired the valve is opened and the propane ignites.
As this will be a vented stove I don't see a need for an oxygen detection sensor. The control valve will close if the pilot flame is extinguished. The only other safety issue I can contemplate would be to disable if tipped over like a Mr. Heater does. Considering that there will be a stove pipe "securing" the stove from tipping, I am inclined to not include that as a must-have feature. My only other thoughts right now are alternative enclosures if this proves too big for an ammo box. I guess I should mention that I will of course remove the burner from the stand it is currently on.
This is still just a concept right now. I welcome suggestions, barbs, and sundry smart-alec comments for or against making this real.
