Tim a little tip that might help is to build an access hole on the other side where the chimney is and start a small fire there. This way it pre heats the chimney first an then start the fire in the fire box. it should almost start right away because the draw of the hot side and once closed will keep the fire going. That stuff will burn off to ash over time. Now back to the video.

They do the same on steam locomotives, the steam nozzle pointing upwards in the chimney, creates a vacuum and pulls more air into the fire. When the fire burns but the chimney is still cold, you can blow some compressed air through the nozzle to suck the exhaust gas into the chimney, 5 seconds will be enough to get it started, from there on it will keep on going by itself...

Hey Tim! I would recommend adding a port or fitting on the inside of the chimney that would let you blow air up out through the chimney while it’s warming up. That should increase the draw of air through the rocket stove via the Venturi effect (like an airbrush paint gun) reducing the total time it takes to switch the flow by a considerable margin. If you went the fitting route then you wouldn’t need something all that large. Just a half or 3/4 inch copper tube bent at a 90 at one end and with a funnel on the other end that you could attach at a handheld leaf blower or a supped up hair drier to.

That way I can see the hot air trying to push its way up the chimney, (rather than trying to solve all of the Navier-Stokes equations.) Another way to check is to make a model of the chimney 7x smaller and submerge it in water, and then use different colours for the different temperature water, (because water is about 7x more dense than air.)

As I understand, the trick to rocket stoves, is that you are buring the fuel at a very high temp. Which is how they get their efficiency. So you don't want to be taking heat out of the burn chamber. In fact, you want to insulate the burn chamber. You take the heat from the exhaust. (Think I said similar on your previous video). Also, you will probably find that if you have the air drawn through the fuel delivery chute, the burn will work it's way up the fuel stack and the lot will be burning. That certainly happened on my first attempts. If you air seal the fuel stack once you've filled it, and add the air to the burn chamber separatly, that might work. On mine I just replaced the fuel stack with a big fire box, lined with refactory. So I just load it with wood, shut the lid and let the lot roar away. The whole thing is the burn chamber. I also have no grate, for wood I've never needed one.

Thanks, Gonzo. My plan is to take heat out of the system in 3 different place - the primary boiler won't be taking much out, I think so shouldn't affect the burn.

Add another hatch on the flue side to start a small fire to draw a draught from the fire box. start that fire first and once it gets nice and hot and a draught has formed, light the fuel in the firebox. Lots of old wood fired brick heating stoves use this method to get the draught going. They are usually stacked vertically with the flue fire over the firebox but should work just fine with your design. Dont worry about the ash since it is just a smal fire to start the draught, most of it should be drawn out with the flue gasses. As for heat loss, once you get your proof of concept weld the entire seam. I am sure there is outside air getting in reducing the efficiency by reducing the draught from the firebox and cooling the flue gasses as well.

As I understand rocket stoves, the idea is that one wants the combustion area as hot as possible to release all the gases within the wood and then to be sure one can add a second air input ABOVE the fire to create a secondary burn of any gas that does not burn in the primary fire. The chimney emission should be clear with dry wood which should have a large surface area to volume and the stove should start and reach operating temperature quickly. The amount of heat that can be extracted from a wood burner with the boiler above the flames is 80%+. In my wood burner if I don't have the water circulation pump on I can easily boil the water. If heat is being extracted from the combustion area one is reducing the efficiency and wasting energy as unburnt flammable gases will escape. The entire outside of the stove can be covered with fire brick to reduce heat losses and maximise the opportunity for heat transfer to a boiler with the proviso that you don't want things so hot that any boiler materials melt. Good Luck!

Based on my own experience, the steel will not last long in the hottest parts of the fire, with moist o2 (aka Irish Air) flying past it. Even in SoCal the air is wet enough to rust hot metal at high speed. The burn box needs to be fire brick. So... That gives you a cheaper / faster way to prototype new burn boxes: Stack bricks with a bit of high temp morter to hold them in place. Then /after/ you get the burner working at full pace, build a metal box to hold the bricks. The grate should be cast iron or something that wont rust as fast, but it can also just be replaced.

You also need to make a hard kink in the airflow, to force the air to drop the ash particled. Else you'll blow the ash and some amber pieces out of the chimney or they will choke the chimney in no time. You can also add water to the collector for the ash. This avoids that vibration will dust the ash up again. Just make sure to use stainless here, ash/water mix might otherwise eat your metal away. With an outlet you can easily and dust free drop the ash/water mix and won't even suck in air through the port if you refill the container at the same time (you basically flush out the ash with water until the water is clean and then close the port again).

And please don't get me wrong, it's definitely not meant as criticism! I simply can't resist because I'm a proven (or is it confirmed?) inventor too: 1) I think that it would be much better/more efficient for the draw/heat if the boiler would not be going completely through the fire chamber. In my opinion everything would work better if the boiler would stick out more above and therefore leave a small gap underneath it's bottom and the bottom of fire chamber. 2) I also suggest to wrap the copper pipes around the outside of the chimney and insulate everything well. In this case the draft wouldn't be hindered so much. Additionally the chimney pipe could be cleaned from soot a lot easier. 3) Maybe you could also wrap nearly the complete stove with copper pipes and especially with insulation. 4) If you like to increase the size of the stove and boiler in the future, maybe an old inert gas/acetylene/oxygen tank/bottle can be used. I'm eagerly looking forward to watch your next video. As always: Thanks a lot for making teaching explaining recording editing uploading and sharing.

What temperatures are you expecting for the firebox once insulated, and do you need to be able to “pull the plug” at any stage during burning to quickly get to the innards of your firebox? That might dictate the materials as some might be easier to remove and put back into place than others. I read rockwool (as many other mineral fibres) becomes crystalline above a certain temperature though, at which point it is more likely to end up in your lungs through vibration etc of the whole contraption- maybe perlite all round is better as a first layer, then rockwool around that? My gas forge has a 1” layer of that koawool but it’s not exactly a fair comparison as two propane burners create insane heat and there is no flue. I have managed to forge quite well with charcoal fire with a hairdryer forcing air in from underneath, so with that cone possibilities for you too I feel- maybe a battery powered blower for the first few minutes to get the water boiling and the glue to draw? It’s going to be a small cost but help make the startup process so much more efficient. By the way if you ran that setup a lot a lot, you might also see some oxidisation of the steel so may need to have parts like the grate replaced after a while. I’ll stop rambling. You’ve got this :-)

He should try it at least partway open to get more air for secondary combustion

I tried lots of positions and found the best (once it was hot) was to have it closed. But more experiments needed..

I love these videos. Just learning about steam along the way. I'm kind of hoping you do end up building a steam engine now because it'll be such a novel design. It would be so quirky and lovable

Looks well built. Only thing that I don't understand is the reason for the bottom of the round boiler to stick out below the bottom of the stove? In other words, why did you cut the second round hole? I am assuming that it would be better not to expose that bottom to cold outside air but to raise that boiler up so that the bottom is one inch or so above the bottom of the stove.
@wayoutwest-workshopstuff62992 жыл бұрын
You could be right - I was thinking I could try out different positions to see where's best. But water is good at layering by heat, so I only need to boil the top-most part

I’m excited to see your steam boiler working ! Are you going to have a vessel to hold the steam or direct to perhaps the drivers ? I wonder what the pressure of the steam will be ? Copper or water pipe ? That being slender will work well on your narrow gauge project ! A vessel for the cold water a hopper box for fuel I would guess is next , can’t wait ! Lol

What do you need to do is have a pressure gauge and seeing how much pressure you can produce in that boiler. In the miniature World a lot of the steam engines have the pressure gauges to see how much power the boiler can hold. Most small boilers will hold up 200ps in the engine. If there was a way I can contact you or give you some information I'd like to try to help that give you some ideas
@wayoutwest-workshopstuff62992 жыл бұрын
Thanks but this is not a pressurised boiler - it's going to be a flash-steam boiler. So the steam pressure never rises more than the pressure of the water.
@paulreinhardt60522 жыл бұрын
It looks like great fun and I love what you’re doing, but practically, do you really want to wait 20 minutes for boiler pressure every time you want to move a wagon of branches? While not nearly as exciting, seems like a gas or electric motor would be more appropriate.
@wayoutwest-workshopstuff62992 жыл бұрын
You're quite right, Paul. It would be a serious negative if I can't improve on that. But getting the fire hot quicker should be quite easy, and when the floats are in position in the first boiler there'll be much less water to be heated up - so there's still a chance it could work

@bendordoy48152 жыл бұрын
Tim insulation iedas have the whole thing ceramic coated by a company that ceramic coats exhaust manifolds that should reduce the heat loss through the sides of the stove and increase the heat of the gasses and protect it rusting more.

Steam locomotives / engines have water injectors in which you open the outside valve to let cold water in, close that, open the inside valve to let enough steam in to equalize the pressure before letting the cold water in. Some are close to the boiler so that they can be left to heat up to near 100.D.C. before injection to reduce condensing

Have you thought of starting an online discussion area, such as a discord server. That way you could post pictures like your chimney blueprint and then people could either agree or advise you live before you actually go ahead with it, instead of you doing a project only for a commenter to point out something crucial.

At that point i would probably start thinking about making boiler a hollow cylinder around the chimney with ribs (like on electric motor) on the inside of chimney to catch more heat.
