stove comparisons

Aug 07, 2009 09:27:55

Has anyone seen or made a table comparing the relative features of the different kinds of alternative stoves? Am I the only one that gets confused by them?

I think it would be super useful to have including features in the table such as typical min & max functional sizes, efficiency, type/description, how often has to be fed, exhaust contents, min & typical costs, off the shelf models links, pros/cons,... has anyone seen anything like this?

Lacia,

Can you start with which contraptions you have in mind?

I would imagine it would be good to separate cooking from home heating ...

I am going to try and use a soapstone wood burning stove for heat...and cook on top of it so cooking may be the heading of many columns for 'uses'....

If you are talking about a metal woodstove with soapstone slab sides (very pretty, I've seen) then it's an out-of-the-box solution and the manufacturer can tell you whether it will cook well, hold a warm temperature longer, or what.

Masonry heaters and Rocket Mass Heaters are primarily for heating a home in cold season, cooking or baking can be a secondary design feature.

Natural Building does not come in standard sizes or functions, it's a custom-design, make-it-work-for-you world. You can build most of these devices in a wide range of sizes, provided that you test it out and adjust the proportions if needed.

We do include a rundown of a number of different fire-powered options in our workshop, including Franklin stoves, Rumford and other fireplaces, ovens, cooking Rocket Stoves, and camp stoves.

Check out our website at http://www.ErnieAndErica.info/firescience ; there's a short comparison of 4 different technologies at the end. We've added more to the workshop since I put this article up online.
You can also view some pictures at http://picasaweb.google.com/eritter/
These are only the pictures that I own or have permission to post; more examples are available at the workshop.

Here, in table-like format, as much as I am willing to post so late:

Item: Purpose - Burn Efficiency
Fire: Burning - Various (Biofuels can be carbon-neutral, fossil fuels add to biosphere carbon load)
Fireplace: Watching fire burn (may provide heating, cooling, cooking) - dirty burn

Stove: Cooking (pots/pans), heating (short term) - burn varies from very dirty to relatively clean; a few designs are very clean
Rocket Cookstove, tea stoves: cooking (single pot), relatively clean burning
LoReNa or The Good Stove: Cooking, 2 pots; medium to clean burn

Oven or Kiln: Baking, curing, heat-chemistry (burn varies, often dirty)
Furnaces: Burning, Melting, Smelting, Heating (often dirty / carbon-heavy)
Chimney or Hot Stack: provides draft, exhaust transport, can improve burn efficiency

Masonry Heater: Heating, warming, (long term) heat storage - optional oven or cooktop on some varieties. Burn varies from medium to relatively clean
Rocket Mass Heater: Heating, warming (long term), radiant heat (quick), storage - optional cooktop or other devices; burn varies from relatively clean to very clean

Hope that helps.

What did Franklin actually invent? Wikipedia's description sounds like something much more sophisticated than what we were taught about it in highschool ("the fire goes in a box and so the heat stays in the room more instead of going out the chimney, ergo Ben Franklin = genius"). It has baffles and an inverse siphon. . .and then something about a "smokeless fire". . .but it doesn't sound like the fire is burning sideways...how did the ancient L-fire/Dakota fire invention get lost on Franklin, and the masonry heater invention. . . ?

Intersetingly, he said he didn't patent his idea so as to serve the world, but someone else in England stole the idea, patented it, un-improved it, and made a fortune from it. . .hm. . .so what did Franklin actually invent? is the inverse siphon actually doing the same kind of thing as a double-shoebox design? are modern wood stoves actually Franklin stoves at all? I'm confused. I think the Wikipedia article is written rather ambiguously, and this is a subject where the details are super-important.
