Wow, thanks!

Thanks for your compliment. And be carefull not to literally BOIL the water, because then you get dangerous steam.

Thanks. And I indeed did some presentations about new versions of Microsoft software and other cases.

@@RobertJHGisolf i knew it. Hats off. And if you escaped corporate then congratulations are in order.

Thanks, you're welcome.

Thanks!

+Pef273 Well, thank you then.

Thanks. But as far as I know you can't do this with SketchUp. The animations were done with 3dsmax. Then I exported it to Sketchup to make the construction drawings and have them with me in the workshop.

I see. It's a job well done either way. I'll be building a Rocket Stove in my mud house in Shiraz next winter. Can I incorporate some of your design? TY Saeid

Saeid Momtahan Sure, go ahead. We all learn from each other. What design do you want to incorporate?

Not sure Robert. I'm looking at different designs. But thanks for the permission. Saeid

I want to weld up a stove with my powertig welder this fall. I really need something cheap to run to heat up my work space.

The temperature at the flue pipe is around 40°C when I have a big hot fire. I have a rather classic chimney, so that's fine for the flue to leave the house. And thanks for the compliment, and your sharing.

Good looking and good efficiency. Good stove!

Thanks

Пожалуйста. Спасибо за ваш комплимент

Yeah, what he said!!

Thanks. Good idea then. You could also feed the secondary air below the eye, to make sure the oxygen is there.

Thanks - We are experimenting with a waste oil rocket water heater for our hot tub using the corrugated stainless steel coul out of a Halsted 24KW gas boiler - it holds 2 ton of water!

+chris gorman Thanks. I am not commercially producing this design yet.

Oh really?well please keep me in mind. Maybe we could hammer out an agreement when that time comes?i love the craftsmanship & thoughtful design. A very nice american product.

Благодарю за комплимент!

Yeah, once you die of Carbon Monoxide poisoning... That is a smoker in the house and that equals death... Even with an induced draft blower by the way the exhaust is designed. You probably find out from cartoon to reality that this is a fail... Don't kill yourself by poisoning yourself in your home with cartoon engineering...

it amazes me how everyone is using a very stupid design for all their indoor rocket stoves and yes I am talking about the one in this video believe it or not it is a very wasteful design.

@@ClovisX Death

Have a cartoon guy in the house with his hands around his neck gasping for oxygen other than carbon monoxide. And for you earthers of ignorance. Carbon Dioxide is Conditioned as plant food... Really...

It’s actually a very good design and based on many principles already in use in contra flow masonry heaters. The only thing missing is more thermal mass. Can’t say I’m crazy about the extensive horizontal fuel next to the wall. Somewhat awkward and dangerous. I have a masonry heater that draws air form the basement and have enjoyed more than 25 yrs of luxurious, efficient heating.

I already showed temeratures in one of the videos in my playlist. So see kzfaq.info/get/bejne/hLl5h9VhqMWVoZc.html

Thank you very much. The presentation was done in 3dmax Studio.

+264fan I don't quite understand your question. But generally speaking the flow trough the stove must be the same. So the surface of the inlet must be the same as the surface of the exhaust.

Thanks. And Rocket Stoves are often used for greenhouses. See the Internet. But if you can use it for your greenhouse depends of the size of your greenhouse. My model works fine for my large living room, but there is no big fill box, so you have to add fuel every half an hour or so.

Sure, I've build it. Just look at the othe video's showing the build and testing.

You are right, in real there is a pipe with damper to shortcut the long horizontal pipe until the chimney draws enough. Вы правы, на самом деле есть труба с демпфером, чтобы обрезать длинную горизонтальную трубу, пока дымоход не наберет достаточно.

I think that the vortex portion of this is meant to get so hot that the off gasses of the combustion are burned off before leaving causing it to burn clean, which would allow for no creosote build up.

From my experience ... re:- ther are other ways the creosote build up will happen, and it is just by the starting and shutting down of the stove over time, hot & cold condensing plus the accumulation of ash carry-over will eventually create creosote and ultimately congest the flue pipes. Access to cleaning horzontal flue pipe is an extreme concern once installed, especially inside a residence. The only way the concept of scavenging heat from horizontal flue pipes would be to direct the flue straight outdoors, then have your 'runs' confined in an insulated heat exchanger with clean-outs at each of the horizontal runs.

This is an Open-Source suggestion. I'd like to suggest you consider the following:- The feed tube, I've found the angled style tends to cause the fuel to hang up, so we only design vertical feed tubes that are 8"×8" and 18" to 20"+ in height from the top to the removable grate for loading of various lengths of fuel, but the feed tube actually extends a further 4" down to incorporate the ash pit. The horizontal chamber that leads to the riser is 5" ×5" and approx. 10" long, we welded in a 5"×5"×5" square pipe to extend the ash pit, this has extremely improved the combustion efficiency & ash pit capacity, plus much less ash carry-over. The riser is 5"×5" and about 33" in height with an 1 1/2" to 2" clearance at the top. The reason for the variable 1 1/2" to 2" is whether you leave the tank with the domed finish or if you cut off an 1" or 2 and install a thick steel plate(gasketed). Also the riser is insulated with a 6" 12 gauge metal sleeve, and a perlite/refractory (water-based) paste insulation. This is encapsulated with what we refer to as an upright 100 lb. propane tank. The 6" flue exits about 16" above the bottom of the propane tank. Just above the flue the propane tank is cut in half and rope-gasket with clamp-downs used for cleaning and maintenance and inspection. The stove sits on a steel table 17" high for several reasons, easy claning of ash pit, easy loading of fuel, easy access and viewing of primary glass door. I must admit, I am quite envious of your vortex and secondary air plus the outdoor and primary air concepts. We've been able to use various fuel sources continuously, from sawdust to wood chips to wood pellets to sticks to scrap lumber, we found different oils work, used, vegetable etc. But, can dirty the system if not careful, don't like oils anyway. CHEERS! 🍞&🌹's

Beacase the combustion is so hot, there is no creosote. Creosote is the result of a too cold combustion. The only exhaust of a good rocket stove is water vapour and CO2.

@@RobertJHGisolf No stove is 100 percent efficient. If the chimney of a rocket stove was to go straight up without obstructions then I would agree with you but as his goes sideways for half the pipe and is a single walled pipe which bleeds heat into the room for room heating reducing the temperature in the chimney (which aids in creosote buildup) then the draft effect on the stack which aids the burn in the burn chamber is reduced. The fact that the stove is operating at less than optimal temp and draft and the added feet of horizontal pipe there is going to be creosote. It is as simple as that. If he got rid of that horizontal and went straight up then I agree with you...

Hi, how is that 5" square steel working? Is it your riser? I thought steel degrades in the high heat of rocket stoves?

정말 감사합니다

+Otto Weber Thanks. And did you mean the famous 3D example teapot?

I am very curious. When will it happen?

Thanks for your suggestions. But there is no need for more combustion. Measurements of the flue gasses show a very low amount of particulate matter. And that with a relatively simple secondary air supply. So why should it become more complex.

Thanks. Since I replaced the tube with the vortex vanes with an RVS version, it still is fine. The thin inner wall of the riser pipe is a bit distorted, but still holds.

Thanks for the compliment. People already described how to heat water, there are several KZfaq video's showing that. The flue pipe of a (correctly build) rocket stove is not very hot, so that is not a good place to get heat. A copper coil water pipe in the drum is far more productive.

Thanks. This is my first rocket stove heater, a Proof of Concept. And yes, all the parts are in some SketchUp files. A will do some minor changes, mostly replacing the inner mild steel parts with stainless steel. Perhaps I can then find someone who wants to produce it. But transport is perhaps to expensive? I live in the Netherlands.

Robert J.H. Gisolf quanto costa? money

Interesting idea, but I can't completely imagine your idea. Perhaps a drawing can explain? But "white hot" is not a good thing for steel, even for Stainless Steel. And I'm not sure if the wood gas flue injected with air can get the steel to "white hot" temperature. For that to happen you need for instance acetylene and pure oxygen?

Thanks. The answer about the used program is already in my answer to Amon Nouse: 3DSMax

но на самом деле, что ...?

Thanks. It is my own design, but based on a lot of information available on the Internet.

Thank you. I think you have discovered a few minutes later that I actually built the design. I use it in my home now.In a friendly company they have 3ds Max. I may use that when the designers do not need it. I exported it to SketchUp, to draw the building plans.

If you mean rocket stoves generally, just google. If you mean my plans especially, I'm in the progress of producing them.

You can roughly measure dimensions from the animation by relating them to the riser pipe, which is exactly one meter long.

Я не понимаю твой вопрос

Thanks. And apart from the 3ds files I have some draft SketchUp drawings. But not commercially ready. If you are interested, how much would you pay for it?

Robert J.H. Gisolf. I would like to buy the plans. Pleas contact me if possible. Alexsorkin@me.com

You're right. And I love Stirling engines. I have build a small one myself.

How about a Manson engine? Ever put a sterling engine and a Manson engine together to make a hybred engine?

zero6269 Thanks. I used 3ds Max. Read the comments and answers. The answer was there already.

The clue of the rocket stove is that it burns all the gasses at high temperature in the servaral stages of the combustion. First in the very hot burn chamber and what is left is burned in the very hot insulated riser.

Thanks. And sure, I use a fan on top of the stove that gets it's power from a Peltier element. AKA Ecofan ®. Google it. The blades must be real gold for that price...

You can see part of it from 2:40 to 3:00 in the video. But it also streams along the sides of the inner firebox and flushes the front window to prevent soot on it.

Just look at my other videos. Its fireproof concrete.

+David Vosmik Thanks. The gap must form a cylinder with the same area as the circular area of the inner diameter of the riser. I wanted to experiment with that dimension. But no, I now never adjust this anymore.The dimensions for my stove were based on the standard one meter stainless steel flue pipe available on the (Dutch) market. Again the surface of the area between the outer diameter of the riser and te inner diameter of the outer casing must at least be the same. The longer the way the flue has to travel, the longer the time that it can exchange heat with the outer casing. That's why my exhaust temperature us so low.

Perhaps you're right. I never measured front and back of the drum on the same moment. I will do that some day. I will also think about a half circle plate to insert into the drum behind the riser to force the flue to the front of the drum. Thanks for your comment.

@@RobertJHGisolf Thanks for the acknowledgement!

I don't understand your suggestion. Why would I compress wood gas?
