Turbo-furnace a thermospan from a thermos!

Turbo-furnace a thermospan from a thermos!

One autumn day we went camping with my friend. It was already cool and by the end of the day a little snow began. At the halt, we got lunch, and Sanya began to heat food on a gas burner. As luck would have it, the gas ran out, and we only warmed up the food a bit. We talked about burners and my friend told me about a stove-grate. I was interested to see such a miracle of technology. Upon arrival home, I opened the Internet and asked Google's nerdy. The more I watched, the more I was surprised. Everything is done very simply, roughly speaking, this is an ordinary tank into which oxygen is blown from below, thereby enriching our bonfire. It's very simple, as I had never thought of such an idea before, probably I just didn’t set a goal. I look through the pages and see that the people themselves are making pretty good options. There are also purchased options, one of them is the “Airwood Light BM” turbo-draft stove.

Do not get it wrong, this is not an advertisement. For me, this is just a model for another homemade. Of the minuses for me was: the high price tag and the location of the fan and motor are close to the fire, albeit iron blades. Having thoroughly considered the design of both purchased and various home-made, I did not understand one nuance. Why does the useful air from the turbine crash into the solid interior wall? I found the answer from the seller like this:

"A feature of the Airwood Euro BM model also lies in the fact that the space between the two walls of the stove (between the combustion chamber and the outer casing) is virtually airtight, that is, all air from the discharge unit (blower) is guaranteed to be supplied to the combustion chamber."

Maybe it’s so, according to YouTube videos, it heats water quite well and only inferior to gas for a couple of minutes.
The wall that embarrassed me.

In my opinion, this is not good, I would try to make sure that the air would blow as much as possible from below. Still cold air will “crash” into the hot wall and deform thin steel.

Okay, it's time to get down to business and check everything yourself.

Material:
Old waste thermos
Steel and aluminum rivets 3.2
Thin walled pipe
Galvanizing
Steel bar
Motor and wire
3 bolts and nuts

Instruments:
Riveter
Bulgarian
Bor machine
Scissors for metal
Screwdriver / drill

I found in the kitchen an old non-working liter thermos. Immediately the thought, why not make a stove with it.

I decided to cut the thermos strictly in the middle. I think if one part fails, so the second so sure :)


At this stage, my opinion was divided. If to do from the upper part, then it will be inconvenient to throw fuel into a narrow neck. And if you use the lower part, you need to come up with a mount of the internal combustion chamber. Oh, I wasn’t doing it from the top !!!

In the upper part of the thermos, the inner flask is already fixed, and it remains only to make the bottom. For this I use a marker, a regular sheet of paper and scissors for metal.

Paper is needed to even out borders.

We insert paper, connect the leaves, and mark with a marker. In this way, you are guaranteed to be evenly marked circle.

I cut with scissors.


I trim a little more along the edges and bend the bottom.

It turned out interesting, for fans of autotuning, you can attach it to the exhaust pipe :)
In the role of the bottom, I use a thicker stainless steel.

I will not say thickness, about 1.5 mm.

I cut off the grinder! Be CAUTION With this tool, glasses are mandatory and replace the circle only with the machine turned off.

On the emery, I “finish” the circle.

I drill holes in the stainless steel and with the help of steel rivets I attach the bottom.


I pass to the top of the grate and think over the design. It is required to make a windproof screen and a stand for dishes. To make an idea a reality, I’m doing such a thing. I cut a strip of galvanized

And bend her

I drill holes in a thermos and in a strip. Using steel rivets, I fasten the strip to the thermos.

He joined the splice butt and riveted at both ends.

In the role of a windshield and stand, I use the same galvanization.

If anyone will do, then select the sizes "for yourself"
Here is such a windproof screen and stand, I got it.

There will still be holes, below in the photo you will see.

Since I wanted to make everything compact and convenient, I had to take a steam bath with the search for a suitable pipe diameter for blowing. I planned to hide the pipe inside the grate.

Well, here's something more or less suitable. I took this thin-walled pipe from a broken floor fan.
Also there was such a little thing.

I bent it under the body of the grate.
I decided to fix the pipe to the body of the stove using this connector :)

The pipe is fixed firmly and does not fall out.
Mark the inner circle with a marker and cut out the circle.

The photo shows that I sawed up a bit of my pipe fixture to the stove.

I cut a circle with the help of my bor machine and a small circle. Uhhhh, the stainless steel “ate” as many as two mini circles. I drill holes and attach the “air adapter” to steel rivets.


I nevertheless made it so that at least a little could be seen the bottom of the inner chamber. The version of airtight air entering the combustion chamber confused me a bit.

Looks like a hookah :)

Motor and its mount.
Although the pipe is far away from the fire, I still decided to make the galvanized blades.

Connected to a voltage of 3V and checked the air flow. For such a baby blowing pretty good.
I made the motor mount from two galvanized bars. To do this, cut two bars of the right size.

I solder the wires and fix the motor in the tires. I use ordinary aluminum rivets.


For mounting in the pipe, the shredder must be bent. We cut off the waste tire.


We drill holes in the pipe and fasten the motor. I drilled with a drill 3 and fastened with a bolt and nut.

Just in case, I decided to make a universal stove. And suddenly you forget the batteries or the wire breaks, anything can happen. Therefore, I make another adapt (I don’t even know what to call it) for natural blowing from below.

As always, galvanizing.

To make the grate stable, I use a steel chrome bar

I bend on one side.
I cut a shredder for fastening the rods.

I cut the shredder into the necessary pieces and rivet the bar.

I bend and check my idea.

I insert the galvanization to the stop, and a gap for air is obtained. It is desirable to put it on the leeward side. Shchetnochka stands confidently and does not stagger. Holes about which I spoke above are also visible.

If the dishes are wide, then you can insert up.

The thermos lid can be used as a last resort as a cup for heating water. A plastic insert, like a mini plate.


Words by words, but it would be necessary to test the chipper in real conditions.To do this, I went on a small solitary hike to the local forest. My goal was to go about 15 km and test my home-made stove, the grate. It was February 25th and in the morning the snow fell and it froze a little.
Maybe someone will like a couple of photos of the morning forest.


I found a couple of logs and settled on a halt.

Folded Ashtray

Normal mode


Turbo mode

I connect a shchepochnitsa to usual AA batteries. 3 volts.

Feedback without pre-decoration: specifically, I did not search for dry firewood, breaking branches from fallen trees. The branches were with a small snow cover and under it a very thin layer of ice, like icing. In the hands of this layer melted. In a word, the wood was damp. In the usual mode, my homegrown stove puffed and smoked like a steam locomotive, flames burst out from time to time and it was not realistic to heat food, just smoke something :). But when you connect the turbine it became noticeably more fun. The coals swelled, and the fire burst forth with a steady flame. In turbo mode, of course, more fun things are happening, just have time to throw firewood. But still, it seemed to me that the air flow was not enough and I would drill more holes in the bottom. I think that such a small stove is suitable for one person, for a maximum of two. She will boil a mug and a pot from under the flask, but something more, I think it will take a long time to wait. Again, it is necessary to test in real conditions.

Small videos on the operation of the stove in turbo mode.

I am glad to have good and positive communication, it is pleasant and useful to communicate with smart people. yes

From myself I can recommend another oooooochen (in my opinion) worthy of interest / hobby. This is a visual observation of OGKs (deep space objects) or as it is fashionable to call Deep Sky on the Internet (I hate Englishism ireful ) Well, and observations of planets and the moon. I also had an interest in outer space since childhood, plus crowds of science fiction books re-read, did their job. And now, although not very often, I choose to watch and take a picture of the OGKs. Astrophoto is a very, very hard task. Firstly, all optics cost space money, secondly, you must be a maniac of the night sky and software to get a normal photo. But I like it, and I'm happy with the result.

Well it turns out? All Minsk bicycles in my childhood were equipped with B17 Standart Black. ??

Not. The manufacturer of our "adult" MMVZ bicycles was not bothered by inventing a gravy, they just copied from Brooks, that's all smiles

PS. As a joke, MMVZ, we decoded "it is forbidden to carry small milk-suckers" and, on occasion, always told the children younger, and laughed !!! xaxa
Well it turns out? All Minsk bicycles in my childhood were equipped with B17 Standart Black. ?? dontknow pardon Well it is, only the holes are not the same, but "more-less-less", and rivets are not visible ......)))))
..In general, what a tendency I noticed: the “Classic” (in everything) as a result turns out to be the most convenient and reliable ... In my childhood, they would give everything away for a bicycle with a frame “not like that of the MMVZ”, and with a “not such” seat. ...
And now I see on fairly expensive models the usual parallelogram line-up of the frame, and (in, on you) the usual "collective farm" saddles ....
.. Moreover, this is not only a matter of cycle issues ... No matter how many Teflons and ceramic coatings are invented, there will always be a cast-iron frying pan! )))))
No matter how many “Fokin plane cutters” and “smart cultivators” are, the usual chopper and bayonet shovel are still more convenient ...

No, how can it be, if it's a worthwhile thing?


As always, I go from far away. I was born and grew out of town (2-3km), I had a happy childhood. Forest, river, lake, bicycle, football, other people's vegetable gardens, fishing, and other children's joys. But time is running and we are growing, but the moments in our memory from childhood remain with us forever. So with the bike. As a child, he rode a "grown-up" bicycle and, together with his "friend", moved the whole district. Now there is a great mountain and evening ride through the coniferous forest, for me for happiness. But the trouble is, modern seats leave much to be desired. After a ride of 50-60 km, the opa turns into a continuous pain. Where are those comfortable leather seats with springs that I ride on? Having been tormented with such inconvenience, I firmly decided to deal with this trouble. From an authoritative site (Kotovsky) I learn about the excellent seating of the famous English manufacturer Brooks. I ask a friend, and he only confirms the words of Kotovsky. The fifth point is very important for me, and by putting aside money and combining it with my remaining denyuhi, I buy Brooks !!!!!! I did not find Brooks in the Republic of Belarus, I had to pull it out of Kiev, since they have the highest level of service. I’m going to Chernihiv and picking up my caddy. Each person has a different financial level, I can say to myself that the Brooks saddle is very expensive for me. But it's worth it. For a long time I decided (myself) with the saddle model, and decided to dwell on the classics that have been produced since 1898, the B17 Standart Black.

Is it with a set of "blast" (something that the appendix of this is not visible)? I don’t see the batteries! And the scales then lie or what for the whole kilogram?

Well, you are so ........ Nikolaevich, criticize again !!!! Or do not believe my honest word? Believe me, I’m not the kind of person who fools people with their heads, respect and authority mean a lot to me, I was raised that way. Look carefully at the scales, 1 kg is marked with white letters and numbers. In the description of the homemade product I wrote that I want to do everything compactly, and I just hide the blown pipe inside the thermos flask !!! I will not even re-photograph the weight; for me it will be a shame.

Everything is ok buddy ok The best stove is the one that is yours !!!!! For everyone, she is beloved / reliable / unique. Each (if I may say so) "adapts" to his stove and its capabilities. No matter how strange it sounds, but it is. Shchepochniki-go into the woods, drivers-pour gasoline from the tank, coffee and speed lovers-are stocked with gas bottles, and the miners are content with a weak warming up of canned food on spirit-lamps. And for everyone she is the most !!! Therefore, everything is fine !!!!!! The main thing is not to stand still, not to lie on the couch for days, to improve, develop and just be a good person !!!!!

So I went to Ukraine, and bought one useful thing there, this is a class !!!!!!!

I give preference to gnocchi and gas bitter. Gasoline type "Bumblebee" is for travelers by car!

You see, this is your opinion. I don’t think that gas cans are easier to drag. At the same time, there’s a bowler hat (for some reason you don’t stubbornly mention it and it not only has a decent weight, but it’s also not convenient to carry). Yes, and the thermal return of gasoline is higher. In any terrain, in the car, on a boat it will come in handy (which can not be said about the other). Day and night, in any weather. Compact, no need to drag the bowler.Packing you both a saucepan and a frying pan. And you need to cook the soup, eat it. And then wash it and wait another half hour for the tea to boil. So estimate what is more convenient? And by and large (all of a sudden), gasoline is easier to shoot than a gas spray.

On the contrary, I like chippers. The only thing that bothers me is the unbearably high price tag for Airwood, for which people charge money, it’s not clear. And it is also interesting why the manufacturer made such a design in which air stupidly hits the internal combustion chamber. The coefficient of thermal expansion of a stainless steel is greater than that of a metal. To “drive” and rebuke from such her should not be sickly. Maybe it's not a stainless steel, but some alloy.

For example: the bumblebee of my friend smells a little, and there is a specific smell in the backpack, it requires fuel in the form of benzene, but high efficiency,

I apologize, but your friend did not try, the primus, before putting it into the case, placed in a tight backpack and tied up. I have no such problem.
P \ S / And what minus that? I also disagree with some "nonsense", argue your views. Well, let me, too, on everything "dissenting", I will minus ?!

I was very busy and unfortunately I could not write before!

Excellent that so many comments! Each shared his opinion and told his camping days. From the readings it is very easy to single out the main thing: simply for each person, his camping stove / stove / stove will be the best and favorite! Each has its pros and cons! For example: The bumblebee of my friend smells a little, and there is a specific smell in the backpack, it requires fuel in the form of benzene, but it has high efficiency, compactness, and the ability to use it in different places.
For a gas burner, a windshield is required, purchased cylinders, do not forget that the cylinder is under pressure and must be handled with care. High efficiency, compactness, universality of application.
Shrimp pit is acceptable only in the forest area, in the mountains it is not needed at all, smoked dishes, it requires starting dry toplip, batteries are also a kind of addiction. But there are pluses too, it is light weight, no need to buy fuel, there is enough wood, if with a turbine, then this is good efficiency and a little smoke.
The spirit lamp cannot boast of high efficiency, and fuel must be pulled, in my opinion, the spirit lamp serves only to heat canned food and tea, you can’t cook food.
Therefore, all the stoves are good, especially the one that’s yours :)

Well Duc, the fan power is changing. Can I not argue? If the stove is already burning, they will take any firewood, including wet ones. You don’t need to take anything off, it’s quite normal to put dishes with utensils. It is not necessary to attach constantly. Due to the double-walled construction, this stove-trowel has an efficiency of fuel combustion much higher than in a conventional fire and allows burning wood gas. Through the lower side channels of the casing, fresh air enters the stove and is directed into the openings of the combustion chamber. Part of the air rises upward between the walls of the combustion chamber and the casing under the action of convection, where it exits through the special ventilation channels of the upper part of the stove, providing ignition of the wood gas by enriching it with hot oxygen. Everything burns and the temperature is awesome.And it’s good to bite my stove :) I get tired of this :)

I think this will not be a problem. Power hellish :) There are 2 fan speeds, which is also convenient.

No matter how hard you blow the firewood, their power will remain the same (no matter how strange it seems), but the time of return of this power can be changed with a fan.
But you will have to intensively plant firewood (and here they’re raw and will not work in ice). What is quite not convenient to do in this design. As you add fuel, the pan will cool. You take it off the stove.
To get the maximum power from this unit, you can only continuously insert firewood. This is a kind of small “train”; the fireman rarely rests there. And the blast does its job.
It cannot be somewhere else.
I think this will not be a problem. Power hellish :) There are 2 fan speeds, which is also convenient.
And when it’s just light, in a car.


Uhh ... See, you see ... Everyone has a different concept of this very "easy." smiles

For me, "light" is a passenger sedan. When spontaneously, having jumped into the supermarket, we take the kebab ready and go ... (Fortunately, I’m driving in the trunk.
And when I prepare for a couple of days, and I pack the trunk of a station wagon or minivan - this is considered to me not “light”, but “harder” .. smiles And on foot I don’t go to mountain forests ... We don’t have mountains, but forests .... I am lazy in general ....
For you, "tight" is a kung off-road truck ...... Everything else is "light" ...

And this stove is needed for those for whom the concept of "light" is a multi-day walking hike. (Maximum - bike). And every gram of equipment you need to drag "in your pockets" .... It’s really better to cut a sliver than drag gasoline, and even more so, a gas bottle .....
The author, it seems to me, is not why the question about winter was asked. He meant that a thin wall could be deformed when it was blown with hot air and icy air ...
... But about sufficient power - in the subject. I once made a jar boiler from Nescafe. In the car, brewing coffee ... So, somehow the machine stood for half a day and completely cooled. I turned on this boiler ... He was tormented, tormented ... In short, only after I wrapped the jar in a scarf, I was able to boil the water ....

You can use winter, but why not?

The question is not idle, with such a power of this burner.
Warm up and cook in cold for 10-15 degrees, it will be very difficult. Loss of heat at the pan will not be small. I also have doubts about this. You’ll rather freeze than warm yourself with hot tea or chowder.

Well, oo ... It’s you who are used to driving through the forests on the 66th! And the people in backpacks wears. And he wants to not pick up fuel with him for a month, but to cut chips ...)))).

yes Well, there I have a separate economy in this regard. How - I will share the thread.
But I’m taking this "thermos" on a trip. And when it’s just light, in a car. For example, you went fishing for the winter, and especially when there are no "slivers" nearby. Yes, and it’s easier to pour a gram of three hundred gasoline (in addition to a refilled barrel of primus) than to drag along slivers and batteries just in case. Without which it is just a "corpse."

For mini half day trips, I have a mini burner :) on liquid alcohol. Compact, comfortable.

And there is also solid alcohol, also an interesting design. In addition, solid alcohol is useful for igniting the same fire.
Bought recently. Used 3 times. Impressions are the most positive. Before buying, I read / watched reviews of this stove, everybody praises it to one and I agree with them.
You can use winter, but why not?
Soot on the dishes is yes, you can’t get anywhere from this. As for firewood, the consumption is extremely small. And she eats everything, due to turbocharging. For LDPE, I agree that gas or that's how your gas burner is better, because it’s more convenient, there is no hemorrhoids with firewood, smoke.The turbine stove is suitable for long trips, when it is not hunting to drag too much, gas or other fuel. Thus you have an unlimited replenished resource in the form of firewood.
Chaikin on YouTube has a good overview of this stove, maybe you will be interested.

As for the primus, then of course it is power! A good thing! Sorry, not for sale now.
... I use gas stoves and a five-liter bottle outdoors. Simply, I constantly drink coffee (I have such an addiction.). And every time I don’t want to boil water at the stake in a cauldron for the sake of this .... And therefore, I "equipped" myself with a small checkered bag, in which there was a bottle, tile, a folding screen from the wind, a kettle, coffee, sugar ....
From my point of view (in the trunk of the car) it does not take up much space, but if on foot .... Then this bag is the size of the entire backpack ...))))))
This design does not appeal to me. What is its advantage over an ordinary bonfire? The same for smoked dishes, a weak flame (requiring constant "recharge"). A set of all sorts of “gadgets”, and firewood with a touch of snow and ice will not “cheerfully” burn.
I use the usual camping gasoline primus. Economical, flame like a gas burner. Clean dishes from the set (it is also the packaging for the primus). Even after the appearance of gas stoves, I have not changed my "friend" since the 70s.
It is this design, although they are now all sorts of ....

The idea of ​​making a turbo oven out of a thermos is good. But there are disadvantages. Narrow throat, inconvenient to throw fuel. Apparently for this you made a stand so high that it is also not ok (poor stability). How much weight do you have? The latest Airwood model is 490 grams with batteries. Also, a fixed discharge channel will interfere. The wire is also not buzzing that sticks out and will aim. The plate holder is slippery, it can easily be screwed in.
I’ll tell you as the owner of an Airwood turbo oven, it is really devoid of flaws. The design is well thought out and if you do, then you need to seek to repeat the original. But again, the idea is interesting, the implementation is normal.
To each his own, but I usually buy tourist equipment :)



Have you been using it for a long time? The wall into which the air enters is not deformed? Do you use it in winter?
