Sawdust Stoves


Handmade barrel stove provides 8 hours of heating and cooking with one load of sawdust — smokeless and unattended. All gases go up the chimney. He heats over 1000 ft2 of uninsulated building. The basic idea can be scaled up to industrial sized heaters and dryers or scaled down for cooking and camping. Other materials such as rice hulls can be used instead of sawdust.

    Very good idea. If you live close to a mill, they may give you all the fuel you’ll ever need. Not all saw dust is used for compressed wood paneling etc. I suppose you could use some of their bark that’s been removed as well. That too is not always used for something else.

    About using rice hulls instead of sawdust — when I looked into house insulation, I read that rice hulls are difficult to burn. Do they do ok in a barrel stove?

    • Owen Geiger says:

      According to numerous videos rice hulls will work, although I haven’t tested this yet.

      Update: I plan to test this on a small scale. If this works then we’ll have free fuel if we want.

    These are the best videos I could find. Let me know if you find any other good videos or info.

    “The rate of consumption is about an inch and a half to two inches per hour (the figure varies slightly with the quality of the fuel and how tightly it’s packed). A stove one foot in diameter will burn about six hours, and one eight inches across will operate long enough to cook a meal and produce some hot water to wash the pots and pans.”
