@rich991980 I learned that sand is a better insultator than vermiculite. Also wanted to mention the larger the rocket stove, the more fuel you'll need.
@WheepingWillow2 On what planet does sand insulate better than vermiculite? Just wondering. Also thanks for the insight about larger rocket stoves using more fuel!! Who would have thought!!
@rich991980 I can see, you'd RATHER be the RUDE cuss you obviously are, who like any child can't handle any constructive criticism which was intended to help you NOT PUT YOU DOWN. The HOLE being bigger, with same size can, you lose directional power thusly expending more (energy) fuel ,DEFEATING THE INTENDED PURPOSE of the rocket stove design.. Maybe you'll learn someday, instead of getting your panties in a wad. IF, you can't handle the heat, don't do vid's. Native American. Doesn't take twice!
Your mini pocket rocket isn't boiling the large pot of water because of the loss of heat vs surface area of the pot. If you made a boiling pot the same or slightly less in diameter than your pocket rocket heat exposure area, the heat would travel up the sides of the pot and bring the water to a boil. IMO; Your feed chamber is too large, the size of the feed chamber is usually 1/4 of the size combustion chamber or less. This creates more heat, less ash, and requires less wood to operate.
I think you have a rocket stove here. A good design. Some timing info would be nice. Perhaps also get enough fuel to actually see how long it takes to boil. I think you have a good design here!
good recycling :-) I see you have LOTS of self-proclaimed experts telling you how you're wrong, that's good for a laugh. Good for you, to experiment and share with us your results.
Dude, thats not a rocket stove. Your coffee can is way too short, there is insufficient draft to get the temp up for clean burning, thats why you get soot. Please read Rocket Mass Heater, there is a simple mini-rocket stove design that works.
The efficiency of a rocket cooker is achieved by allowing the flue gases to run up the side of the pot. The diameter of the pot here is too big. Look at the designs that encorporate a pot skirt...no use in re-inventing the wheel.
I'm talking about a "rocket stove mass heater". It has EVERYTHING to do with this vid, since he is demonstrating a "coffee can rocket stove", which uses the same rocket stove principles.
If you use refractory material (fire brick, etc.,), you don't have to insulate, because the refractory material 'IS' the insulation... If you don't use the fire brick, then the exhaust HAS to be insulated to create the draft (i.e. fire rushing out and up to the pot), causing the "rocket" effect! (enough said)
its too big..the coke can stoves are the shit..for back country stove and price..and cost of fuel..it cannot be beat..try to get this stove in your back pack..plus alcohol burn clean. no knocking your stove..i am just saying..you sound canadian to me..i wouldnt want this in my backpack in B.C.
its too big..the coke can stoves are the shit..for back country stove and price..and cost of fuel..it cannot be beat..try to get this stove in your back pack..plus alcohol burn clean.
@slapshotjr nice double post while not making any sense! just because you've seen a smaller rocket stove doesn't make that better. I've seen very large ones...the pt is what you do with the heat.
Is the inner area insulated (between the outer wall and combustion chamber)?
If there's not enough difference in temperatures, there will not be a "rocket" effect.
I'm sure you know all this and realize that this video is over two years old, but I'm wondering about the insulation. Some use vermiculite. (I want to make one of my own and am trying to learn from others.)
@RonRay If there's not enough difference in temperatures, there will not be a "rocket" effect.>>>>false. the ONLY reason for insulation is to maximize the heat delivery to the desired zone....you will still get an "aggravated, directional fire".
Check the technical info on "rocket stove" mass heaters. You will find that it is the "insulation" between the primary (upward) exhaust and the secondary (downward) exhaust that causes the "draft" (or "rocket") effect.
Without this difference in temperature, you will not have the exhaust you need to cause the hot gases to travel down. around and through vent pipe, inside the cob (mass) material.
So, yes! You DO need the insulation. I've built them and experimented with the designs.
@Ron you're talking about a mass heater, where an insulated riser runs inside something larger (barrel over the riser). The inner tube is insulated so the hot air rises into the empty space of the larger device, travels down due to the temp diff, into a low exhaust. Nothing to do with this vid. One can make a less efficient ROCKET STOVE (this vid) with a simple coke can, which will heat h2o. It is BETTER to insulate that riser, but not necessary for draft, as can be proven by NE1 in 60 secs.
dude, i was wondering... what if you made the combustion chamber taller? a taller one would create more updraft, burning the fuel faster, producing more heat, but possibly the gases would have time to cool off before reaching the top...
just thinking here, i saw that the flames barely reached the pot in this design.
@lukkbox Haha! dude, you are actually missing the point. ie:rocket stove. It's not quite the same as a coffee can with holes in it. Thanks for the chuckle though.
dude, you won't like this, but please read up on what makes a rocket stove worth the effort before you make silly, uninformed replies. How about having a bit of curiosity and asking the designer--'Hey man, what's the advantage of having twin skins and adding this vermicularwotsit stuff?'.
@lukkbox Did you look into what a rocket stove is? Your comment about pointless and rubbish is ignorant! If you want simplicity light a fire on the ground and cook on it like humanity has done for millennia. I'm not saying the rocket stove is the best thing around, I'm just enjoying experimenting with cleaner and more efficient ways of burning wood. Constructive comments are always welcome.
I would be curious to see a burn off between the two stoves, timing how long it took to boil a liter of water. Done at the same time (wind, temp and humidity same) using the same fuel, split wood from the same 2x4. You really have no idea which is the better stove. It's all about how long it takes to boil a liter of water.
rocket stoves burn wood and are different from a gasifier. The rocket stove is designed to provide all the air and heat necessary for a complete primary combustion. Wood gas stoves are designed for incomplete primary combustion at lower temperatures which releases wood gas that is then ignited above the smoldering wood in a secondary combustion.
you need to raise the pot higher, where it's positioned it's cutting off the airflow.
Fabricate some kind of "X" looking riser that sits on top, about an inch and a half of clearance between the bottom of the pot and top of the stove, and I'll bet it works better ;)
You're right, I'd never take one of these backpacking. It's so big and heavy. It's more of an experimental stove to explore the rocket stove concept. For backpacking I take an MSR pocket rocket, or an alcohol burning aluminum can stove, similar to what minibulldesign makes.
Home depot has it. Its foil tape, I use it if I install a hard pipe clothes dryer vent or similar high temp install. Duct tape(misnomer!!!) is unreliable with this stuff, so is out the window! Don't nickel/dime or take chances,spend a couple bucks more and do it right!
Yeah!! I really like the downfeed design. I've used it in the new heater bucket I just made. Not my idea. I'll have a vid of it in a few days hopefully.
Eventually the whole things gets hot, so fuel sitting on the shelf would ignite along the entire length, and anything stored in a hopper or chute would ignite also.
Need to carefully control where air goes, so there's no possibility of it going up & out the feed chute (where mine failed).
I don't see any way but to continually feed it as you go. Either this type of regular "L" rocket, and you shove chunks right into the combustion as you go, or a higher slanted chute with a tight lid (Or remove the work surface/pot, and drop fuel in, but this would happen often for fueling). This might make it so that the lower inlet is air only (with a damper?) Possibly a passage in under the fuel grate is air inlet/ash removal.
A Instructional video would be nice, great stove im trying to make one my self but their are some things i cant figure out. How do i put in the secound can and the lid thing around it (seen in 0:51). thx.
I made it a while back. As far as I remember, I traced the outline of the smaller can onto the loose lid of the big can, cut a hole with tin snips in the lid a bit smaller than the can and made many cuts straight out to the line, then bent the tabs down and fit the smaller can into the lid. Hope it helps.
hey dude thats wass good demo i made one by my self keep it up save the forest..by hte way you sound familiar your voice lol. it's sounds like the bong master lol!
You dont really have the "L" shaped thing going on and therefore no chimney effect. see other rocket stoves that make huge flames with longer entry passages.
I think a taller combustion chamber wouldn't hurt. I'd also like a way to add heated secondary air for more complete combustion. I'd also like a chimney, both for better smoke control as well as stronger airflow. This model was limited in height to the height of the large exterior can. I've got some 5gal. metal pails I'd like to use next, and try to make a firebrick combustion chamber, in a horizontal setup so the wood falls into it, and a blower fan to make it real hot.

boiling water is no obsession, it gives a measure of the stove's output energy
assume you have 1liter (~1kg) of water that takes 5min to reach 100deg. centigrade starting from it's initial 20deg. centigrade. OK
1calorie is the amount of heat needed to increase the temperature of 1g of water by 1deg. centigrade
calculations for the above noted values....(100-20)*1000= 80kcal...(80000*4,18)/(5*60)=1,11kW
so 1,11kW is the output of your stove+pot assembly
