7/25/2023 0 Comments Rocket stove designHere, in the mid-western U.S.A., the most often used size found in a market (approximately 2&7/8″X4&9/16″ or 75X111mm, about 14.5-15 oz. paint can by mistake or a shorter coffee can, and then the design principles mentioned above won’t be met ī) There is no such thing as a “regular size tin can” as called for in your diagram. One gallon paint cans and #10 cans have a standard size, but without giving the dimensions, a builder might end up with a 1qt. Next, I believe you should be a little less vague on some of the parts of the diagram.Ī) There are no exact dimensions given on the diagram. ![]() ![]() An acknowledgement that the tin can rocket stove is not as big as and therefore is not going to be as efficient as Winiarski’s recommendations, would also be beneficial. Having Winiarski’s design priciples in mind while making the stove will help builders ensure that their rocket stove works properly. Without these principles, a builder is likely to:Ī) use the wrong size small cans (like so many on YouTube), thereby getting the “firebox:riser” ratio all wrong, creating an inefficient design that possibly will either not stay lit or burn fuel faster than the smoke can be combusted, among other problems ī) use sand, gravel or rock which will act as a heat sink, instead of insulation (again, like so many on YouTube), with the resulting effects of 1)sucking heat out of the burn chamber instead of directing the heat up to the cooking vessel, and 2)causing an inefficient low temperature burn, among others Ĭ) let the heat out to the sides of the top of the stove, instead of directing the heat up the sides of a pan (which is part of Winiarski’s design) Īnd there are most likely a few more that I’m not thinking of right now. I’m not affiliated with them in any way, but here is one with a decent diagram. I believe it would be helpful to have a description of the principles of successful rocket stove design as ‘defined’ by Larry Winiarski or at least a link to a website or papers on the subject. Here are some minor points that might help improve this article. I guess I feel a new rocket stove build coming up within the next few days. I’m not a “Rocket Stove Scientist”, by any means and in fact have spent a lot of hours today trying to find out if my new ideas have been tried and published. Yours is as clear as I’ve seen, much better than most. This is one of the best descriptions I’ve ever seen about tin can rocket stoves! I’ve built quite a few myself by attempting to follow directions on various websites and YouTube videos, as well as coming up with a few ideas of my own. If you do build your own, be sure to test it before using it for cooking by boiling a pot of water first. Larger, more sophisticated versions can even be used to heat a home. Want a rocket stove but aren’t keen on building one yourself? Don’t worry they can be purchased. The cook pot sits directly on top of the combustion chamber, so the hot gases contact it immediately after combustion, reducing smoke. The combustion itself is confined to a small, insulated space, so most of the energy in the wood is converted to heat for cooking. The small fuel entry not only demands less fuel wood, but also limits the amount of cold air that can get in. ![]() ![]() With a rocket stove, only the tips of the fuel wood are burned, eliminating that waste (and also eliminating smoke).įresh air enters the fuel chamber from beneath the burning wood resting on the grate, allowing the air to be preheated before it enters the combustion chamber, which in turn leads to cleaner combustion. In open fires that are not carefully maintained, only a small percentage of the heat energy released from the burning wood makes it into the cooking pot.
