Here is something interesting, a rocket stove bbq with lots of instructions:
Anyone know enough to say what would happen if someone used 4" diameter steel tube (well casing)?
4in.
should be fine for this use... too small for a
RMH though.
I'm assuming if the burn tube was insulated, that the bbq would be more efficient, but would the cooking temperature go up (perhaps too much)?
My main concern is there doesn't seem to be a heat spreader or reradiator. The idea of a bbq is to broil, from what I saw, the heat goes straight up the middle as hot gas. It would work fine for his dutch
oven as that would spread the heat around the outside of the pot. It would probably make a great mini oven for one loaf at a time... not so sure about BBQ though. A tray with lava rock might help or a
cast iron fry pan (with no handle) about the same diam. as the bbq (enough smaller so the gasses can pass around it) set an inch or so off the bottom might work too. Most propane BBQs have a "flame spreader". I think this needs one too. Even a few fire bricks or some soapstone.... a pizza "stone" the right diam... if it lasted.
