Mini Mass Rocket Stove Heater pt 1

Pt One of my my gravity feed, mini mass rocket stove heater experiment which will have a wetback. Will be coming back to insulate in part 2.

[@hjt4451]

Daughter is cute. Good job.

[@stevebr551]

In addition to everything else, i really enjoyed your choice of music in the video. well done!

[@hammerdn]

Great concept. Only thing I would do differently is to not drill all those holes along the tubing. In order to eliminate the smoke coming back out the feed tube, open that door at the base to create a decent draft.... Additionally, you might consider drilling only one small hole toward the rear of the bottom chamber to allow just enough oxygen to get in that might help burn the gases that are downstream from the burn tube. Overall, it's a great experiment worthy of kudos.

[@calhiser8265]

Ok you get it that the post flow is important and are keeping it on the puddle on till it cools. But if you yank the rod out of the argon shield while it's still red hot. I would recommend snipping off the oxidized end of the rod before you reintroduce it into your next puddle.😊

[@weihanlin6617]

You don't need secondary air intake holes in a rocket stove. These holes weaken the primary intake's suction and cause flame to come out at feed port.

[@christianandersen7458]

I agree, and also the holes are poor for air mixing. If you really wanted sec. air you need a bit of length to the nozzles - normally I would say 10xDiameter, but less might suffice.

[@rodrigotroncoso3374]

Checkout wiseway pellet rocket stove. They have holes after the primary burner and they slow the combustion, yeah less heat but pellet bag last for 6x more hours

[@Buzzhumma]

Yeah really cool mate. I played around with this stuff on my other channel about 8 years back and made all sorts of version with similar rhs. I got fantastic results in the end. Even made a keg pizza oven. I sat ontop of the 6 inch high out put and then went around the keg and then out a 5 inch flew. The keg was wrapped in a concrete chicken wire mix with a 1 inch space for the heat to pass through. I heated up very quick and made amazing pizza with a door made at the keg outlet end and a peephile I plugged with a timber stoppee big enough to work as a handle to. When you turned it the stopper came out like a plug to look through at your pizza 😋

[@jimrogers7841]

I’ve been looking for designs that would be light since I need to put it in an upstairs room, this looks like one of the best and easiest to go with; my only alterations would be for space and an angled feed. Thanks for all your videos!

[@Red_Proton]

Nice rocket mass heater. I like the back and forth box tubing. If you want to "reburn" the exhaust-air mixture from the wood, maybe a J-shaped piece of conduit or pipe that's inserted through the "air control" door at the front, instead of the drilled holes. It's a thought. I like your build the way it is, though.

[@LittleAussieRockets]

Thanks mate

[@jasonfoster9118]

I' might try one of these designs with the flame tubes all sloping upward a little bit to encourage the heat to create a draft. I really like your concept.

[@sickpuppy011]

Awsome build video, as a fitter turner I loved it, for my 2 cents worth @ 30 minutes on the video I think the fuel tube should be by your left knee. That would get the air velocity going and stop heat and smoke coming out the fuel tube.

[@shackman9566]

Thank you. Rocket stoves are a bit like Thomas Edison's experimentation with light bulb filament materials. I've seen a thousand different variations over at least 15 years starting with Larry Winiarsky's versions. And I've done a lot of my own experiments. It's always interesting to see all the different approaches people take. And the different applications or specific uses for capturing heat.

[@sauravbasu8805]

Can you please share the best design in your opinion ?

[@maryhornbostel6959]

You should follow the basic design for rocket stoves then after the exhaust riser implement your manifold just like they place the bench after the exhaust riser. The initial tall (3 or 4 times the the hight of the burn chamber) exhaust riser is needed to get a clean burn.

[@etiennelouw9244]

These rocket heaters are fascinating. I really want to make one or two with my everlast welder.

[@aidenjohns8248]

great video.. interesting seeing other designs.. great idea for window.. 4 gang chrome switch plate and glass from a small 150 halogen work light, there high temp glass.. but seem to getting harder to get.. and a 4 to 8mm fire cord.. this works well, looks great... but good idea to preheat the glass with blow torch, with a swiping motion.. stops it from sooting up!..

[@Sacwriter]

Brilliant design, I really think you have something there! If I understand your direction, you're trying to create a thermal mass heater that will store as much heart as possible, probably to last all day or overnight. I have two suggestions that might help with that. First, half fill those heating tubes with pea gravel, which should absorb more of that extra heat. Second, how about preheating the air before it gets to the intake, so that you get a more complete burn? Try tacking an L shaped tube along the side of the combustion chamber and around the air intake, so that the heat from the combustion chamber is captured and reused. I've seen this principle used before, and it does make a noticeable difference.

[@LittleAussieRockets]

Thanks mate 👍 the gravel idea is gold 😀

[@andybilakshow260]

i Was thinking the same thing on a comment I read just before. "fill the flue with paper to kickstart your draft"

[@naths1229]

I like your works.

[@billwoehl3051]

From my research, seems to like the riser to go straight up before it weaves back and forth, get the draw going much better. But, I've only made one, working on one with lots of mass for the house with water heating system for even more mass. Since water is a much better thermal battery per pound than concrete and bricks. Add insulation around the first section of riser for even better drawing power.

[@vibrion121]

Seeing your build I was thinking in the zigzag exahust. I ve seen similar approach but more like an S (or Z). I think this is for increase air/metal surface. Great TIG welding skills!

Something like Wiseway pellet rocket stove, I guess? This one could also maybe be used with pellets. just some kind of metal bucket at the top of the feeder and a metal grid in the burning chamber.

[@kenjohnson6573]

Just found you on KZbin.. Great videos. I like that you are taking it past the basic rocket stove. Would it improve things if you made the fuel tube taller and put a door on top so O2 couldn't come in thru the fuel port. On the Oxygen port ( also where you light the stove) would also be an adjustable door. This intake port might need to be a little farther from the flame front. The purpose is to limit the source of O2 and make it adjustable. By doing this, you can create an intake draft so that ALL the heat must go into the stove. None would escape into the air by exiting the intake air tube. Just food for thought. Again, great videos.

[@bharm6974]

Actually, the music is a bit of an interesting touch. Love to see you working

[@sarcasmo57]

Cool design.

[@tolbaszy8067]

Too much smoke coming out of the fuel hopper means poor draft up the flue or too much primary air intake. A baffle just downstream from the firebox would constrict air flow, increase flow rate and create turbulence to aid combustion. This may actually increase draft because the hotter burn will expand into the smoke chamber and the baffle will prevent backflow.

[@andybilakshow260]

a baffle of thin gauge stainless will heat up almost white. Then it'll burn all left over gases.

[@firelces9112]

IMPORTANT: No one should take away heat to heat ie. water pipe/water jacket near combustion chamber that too causes creosotes by lowering combustion temperatures. Instead heat water from upside down barrel or equivalent near the top inside or out( your choice) by this time all combustion should be done. Thumbs up for creativity. :)

[@krafkakyle4768]

I was hoping for a good description of the work. I can watch people work all the time! How about describing how and why?

[@barnie171]

in Scouts we had a 44 gallon drum on the fire with a metal funnel in the top to pour the cold water into it up to an outlet pipe on the side . just pour an amount of water in top and same came out the outlet . similar idea but could control how much came out .

[@davekauffman8727]

Your daughter is a precious child, God has blessed you greatly sir. Very interesting design, but don't insulate it without first finding a way to harvest the heat produced; it's just playing with fire for amusement if you don't use the heat. Cheers from NY State in America :-)

[@ntalyatrshkova4723]

Thanks for the beautiful Dana for help

[@marlonvite4152]

Thanks X3 for sharing your video .... wood burn (oxidizing) ratio should be 1 of fuel (wood) and 6+ of Air ... your rocket stove is oxygen poor at the wood contact.... the wood seem to be chocking the airflow at the intake ; )

[@leslietehaara7099]

Did you substitute copper tube, 25mm diam, elipsted, for your water transporter, stainless steel has thd worse heat absorbtion rate. I love the design tho, thanks for posting.

[@davidmc8110]

Are you touching your plasma tip? 😊 Don't touch your plasma torch tip. At first I wasn't sure what to think of your channel, but I like it. I watched several builds you have done, and you do a good job fabricating and welding your ideas together.

[@groundzero.]

need your air intake in front down low. get rid of the drilled holes on the sides near the back. feed box should be closed after start up. no air coming in the feed box.

[@melroyel2235]

I like this build Great job. I think this rocket stove would be better using wood pellets as fuel. Leave about a 3/4" gap at the bottom for air intake.

[@navigator902]

[@comson66]

good video, If you ever have a problem with your mig welding, move the fan away from your work, the one you put onto your work bench before you started welding, a fan can blow the argon gas away from where you want it to go, onto your work,

[@LittleAussieRockets]

Thanks mate

[@truckerdaddy-akajohninqueb4793]

How hard is it to start, to draft? I wonder if there's a way to put a fan in the chimney to get the initial flow started? Or blast a torch at the base to get the heat to rise?

[@kennithhackett285]

Close off the feed tube make the air come in from the bottom under the fire box plus add a chamber after the fire box that reverse the air flow to a larger section burn the air can achieve 1200 f degrees evaporated fumes come off at a lower temp than fire but are far more combustible

[@LatinDanceVideos]

As always, I'm impressed. Seeing the flames just coming out of the feed box, I'm wondering if this is due to the burn tube and flue being too long. Then I saw those flames stop after the stove heated up. I'm guessing this will take longer to heat up when the water piping and insulation is added. Plus there was different behaviour with different types of feed. (Softwood vs hardwood) So I'm wondering is it worth having a fan while heating up to minimize the smoke and speed the heating up to operating temp.

[@christianandersen7458]

In commercially water heaters you put in a flue gas bypass, and then you bypass during heating of the stack and once the draw is ok, the bypass closes and the flue gas is cooled more in the longer flue gas duct.

[@harrymills2770]

@@christianandersen7458 Yes. Some kind of bypass. Maybe less of a bypass of the stack or heat mass and more of a direct-to-the-chimney damper that you slowly close as it warms up. You could probably rig up a bi-metal coil, like the choke on a gas engine. Getting that column of air on its side moving takes some doing, but once it's going the chimney will keep it going. That's one of my engineering concerns making a rocket-stove mass heater of my own. First off, I wouldn't use metal for the guts of it, unless I were going high-dollar refractory alloy. Better to use fire brick, because the way you get the clean burn is by insulating that riser so it burns at super-high temps. These metal-shop rocket stoves are curiosities.

[@dantronics1682]

the flames coming out the top is caused by the holes he drilled into the sides, the stove should be sucking from the feed which would cause no smoke to get into the room.

[@spiridon2349]

Это не ракетная печь.Принцип работы ракетной печи показан неправильно, идея взята у индецев племени Дакота, рылись в земле две сообщающиеся ямки, в одно отверстие вставлялся хворост, в канале происходило горение и дым выходил через другое отверстие. Печь была усовершенствована и отобрана на конкурсе печей из 3000 вариантов. идея заключалась в том что в вертикальной трубе стенки теплоизолированы и развивалась большая температура, чем достигалась полное сгорание топлива, в печи нет золы, она тоже сгорала, затем газы нагревали большую бочку и уходили в длинную горизонтальную трубу, выполняющюю роль теплоаккумулятора и лежанки, а зтем остыв, выходили в небольшую вертикальную трубу, практически холодными, печь имеет высокий КПД, позволяя небольшим количеством хвроста и наличию теплоаккумулятора запастись теплом на всю ночь. Печь так называется потому что издаёт похожий на ракету звук.

Good Job

[@LittleAussieRockets]

Thanks mate! Half way there.

[@beninston3571]

i like your ideas. but i think some of the ways you try to heat water arent really good for the rocket stove to function properly. i think its probably best to have a insulated burn tube kept as hot as possible with a insulated riser as close to the burn box as possible for the best draw. the outer barrel/gas bottle that many people put on their rocket heaters where the hot gases hit the top and start to head back down is the place you want to take heat from, which only adds to the draw by cooling those gasses and helps them to fall. anything after the exit of the barrel is what i would call waste heat, that can go into heating a bench or preheating water before it gets to the main hot spot. just my ideas.. i hope it makes sense :)

[@LittleAussieRockets]

Thanks mate, I hear you.

[@georgeroberts613]

You've likely figured out by how you have too many air holes to keep your feed tube from burning vertically.

[@firelces9112]

First nice video. Excellent job not short cutting by welding rusty metal. As an experiment try every thing your heart desires. Thumbs up. IMPORTANT: NO ONE should ever choke down a rocket stove, it creates creosote, that in turn creates chimney fires. Always run full throttle.

[@marciogoncalves8821]

O cinzeiro também está inadequado para o bom funcionamento do fogão ( stov )

[@antoncolbo]

Hmmmm... My two cents for all it's worth... The burn chamber/lower tube looks to be larger in area than the rest, so your cross-section area decreases as the "smoke" enters the heat exchanger flue area. (That's going to cut down on potential draw for sure.) Adding so many extra holes in the after burn area will surely decrease the draw potential even with the added height of the chimney. If you want a secondary burn effect for efficiency, you need some way to heat up that secondary air before it enters the flame. (Add a piece of angle iron to make a triangular slot/groove passage the length of the lower tube and over the secondary burn holes so the air has to flow alongside the burner area and be heated before it enters the secondary air holes.) Not nearly as many holes through into the exchanger...only needs a few. At the end of each point where the exhaust changes direction in the heat exchanger, instead of leaving it as clunky 90 degree bends, I think a slice of large halfpipe would help. (Diameter twice that of the flue pipe so it smoothly changes the exhaust direction, with a halfmoon plate to cover it over, then you can just leave the heat exchanger pieces as straight pieces.)

A plaz-arc is great for stainless, chrome and thick carbon but on thin carbon it's really overkill. The grinder really was the best way to go on that very thin sheet of rusty carbon.

[@brianbond7856]

Excellent stuff but as a fabrication guy myself I can't see the advantage of tigging it instead of mig much faster less costly if set at right voltage you can achieve as pleasant a weld as Tig at half the cost if not more and I know the argument is quality and to be honest if you Tig you certainly can mig ???? Puzzled that's all but brilliant stove's though

dear friend, a pleasure to greet. I make pellet stoves, perhaps not at all fantastic, and have refined many ideas that have seemed very attractive to me and I have humbly tried to improve things. I wanted to ask a question since I saw that you were welding with a TIG. I want to start welding with TIG since I have always done it with a coated arc. Can it be welded without filler mixture? that is, with gases, I appreciate your answer, and forgive me if my bad English has been difficult to understand my question, I am pleased to do it in another way so that you can understand well, I live in Chile in southern Patagonia (Coyhaique )

[@LittleAussieRockets]

Hi Claudio Yes you can weld with a TIG without filler wire. It is called fusing, and works best on stainless steel. The metal must be perfectly clean for best results. However the weld will not be as strong with out filler wire, and you have to use pure argon gas, other wise you won't have a stable arc. Keep your tungsten nice and sharp and remember to hold a tight arc length. Oh and one more thing with fuse welding, hot and quick is better than slow and cold.
