If you are maple syropping...................have a look at the institutional style of rocket stove. It would be a little more work to build as most of it is metal, but for an annual even such as that it might be worth the effort. I'd modify the feed though to a down draft to ease the feeding of it. I hate having to bend down to look after a fire if I don't have to. Being tall has its drawbacks.
Well...........yes and yes. They are scaled up stoves but the big difference is really in the clearances and how the skirt is set up to convey heat to the pot over a larger area of the pot therby reducing the amount of fuel needed for the same level of heating. I think I said that right. Anyways here is a complete how to .pdf file you can read on them. What seems to be common with larger stoves like these is the stove is built to fit the pot or at least appears that way.
Here you can watch a video of a different variety of institutional rocket stoves other than the barrel type. These could more easily be made of different sizes than the barrel type. That should get you started.
Thanks for the links. Very interesting. I built a down feed adapter for my barrel stove from a piece of galvanized pipe and a pipe "T" surrounded by perlite. Am still learning though. If you have other information I'd love to have a look.
Do some digging on those sites. You will find more infor than you can digest in more than a few sittings. Just google anything "rocket stove" or "institutional rocket stove". You will find all you need from there. If there is something specific you need, ask me and I will try to funnel specific info to you as I have done here. Otherwise there is just too much.
A simple way is to coat the bottom and sides of the pot with thin layer of sticky mud. It will eventually bake off, and being so thin it won't be too much of an insulator.
Some people rub dish soap over their pots. While this does indeed work, i do not care for the idea of smelly burnt chemicals in my food.
Pomolive scented tea.. EWWWW.
We used the soap technique camping; it does speed cleanup, not sure whether the soot outside the soap still helps absorb heat (seems likely).
The trick is to put the soap on the outside of the pot ;-)
Traditional soap is fat (tallow or olive oil) and alkali (ashes or lye); not much worse than what you're burning when you cook. We pack biodegradable soap in our camping kit for that guilt-free nature-dishes experience, and something simple like Dr Br.'s would be relatively clean stuff.
I never noticed any soap flavor in the foods we cooked out camping. (Smoke, sometimes. Usually, just the absence of flavors like chlorine and spices.)
I agree that the mud trick sounds neat. Clay can make metal rust, so I wouldn't leave it on when you're not using it.
Why would you care about soot on your pot, but not mind coating it with mud? Just ease of rinse-off?
OK, Donkey. I took your suggestion and built a stove with a 6" heat riser. What a difference in output! I had not flames, but a red plasma like heat coming up the heat riser onto the bottom of the pot. Incredible to watch and the boil was VERY energetic.
The problem is that it is eating through the metal cans of the heat riser in short order. So....
I'm now ready to build a new stove from clay/vermiculite and incorporating the downdraft feature. I plan to make it portable by building it in a galvanized wash tub, borrowing the idea from another poster (grizbach - "Is everyone keeping warm...") recently.
How critical are the measurements? I know that the riser should not be smaller than the burn tunnel, but what about the other way? I'm thinking of a burn tunnel 6x8" and a heat riser 7x7". That ok? Not much of a difference but thought I'd ask before embarking on the effort.

daniel: in my experience as I am working now on something of that nature, I have thought of making a heat exchanger and distributing the heat through vents using a slower fan. Now after a few years I realize that mass heaters give out primarily radiant heat, for

vesuvius: Do any of you have experience with using the glass from home oven doors on a rocket stove? I'd like to have a viewing port on my stove but don't want to fork out for new ceramic glass. Any thought as to whether it would take the heat of a rocket stove?
