Я прочитал много комментариев и вижу, что задаются одни и те же вопросы. Итак, я попробую объяснить, что есть в сборке и почему. Это спиртовая печь. Как заявляли другие, можно использовать и другие виды топлива. Во время сборки примерно на 3:14 вы увидите, как он просверлит 3 маленьких отверстия. Эти отверстия, которые он сверлит, являются форсунками пламени. Похоже, он сверлит эти отверстия сверлом диаметром 1 мм. Что, если вы посмотрите позже, примерно в 9:20, первое горение нехорошее, струи слишком маленькие. Затем где-то в 10:20 кажется, что он увеличил размер жиклеров до 3 мм. Посмотрите внимательно на пламя, оно действительно кажется больше. Теперь многие спрашивают, зачем использовать веревку? Веревка используется как фитиль, чтобы втягивать топливо в трубу и предварительно нагревать его. Этот предварительный нагрев топлива в фитиле запускает испарение жидкого топлива. Испарение жидкости происходит при нагревании жидкости до температуры кипения. Это также повышает температуру жидкого топлива в баке. Это повышает давление в баке, вызывая испарение большего количества топлива. Повышение давления вызывает струйный эффект. Вы хотите сжигать только пар, а не жидкое топливо. Надеюсь, это поможет кому-нибудь понять эту замечательную маленькую печь. Я надеюсь, что это хорошо переводится.

I have read through many of the comments and see the same questions asked. So, I will try and explain what is in the build and why. This is an alcohol stove. They are using alcohol. As others have stated, other types of fuel can be used. During the build at about 3:14 you will see him drill 3 small holes. These holes he is drilling are the jets for the flame. Looks like he is drilling these holes with a 1mm bit. Which if you watch later, at about 9:20 the first burn is not good, jets are to small. Then at about 10:20 it looks like he has increased the size of the jets to 3mm. Look closely at the flame it does look bigger. Now, many have asked why use the rope? The rope is used as a wick, to pull fuel up into the pipe and pre-heat it. This pre-heating of the fuel in the wick starts a vaporization of the liquid fuel. Vaporization of a liquid occurs when a liquid is heated to its boiling point. This also raises the temperature of the liquid fuel in the tank. Which raises the pressure in the tank, causing more fuel to vaporize. The rise in pressure causes the jet effect. You want to burn only the vapor not the liquid fuel. Hope this helps someone out there understand this great little stove.
@@blainemickens798 This is a small stove. It would be possible to make one larger, But there would be a risk involved. I would look into using and dismantling a old gas BBQ grill burner assy. Using 30lb propane cans and pipe it in from outside, with a shutoff valve out of the heat. Make a fire brick square set the burner inside cover it with Fire pit Rocks and or stones. That will give a nice looking fire and a warm room. Still this method has a danger use it at your own risk. Search for, Fire pit Tables or Outdoor rock fire place, rocks and stones, see how they are made and try to make your own.
My guess is there are NO holes in the tubing... The way ANY alcohol stove works is that the alcohol heats up (creating an increase in vapors), which then pressurizes the stove, forcing the vapors out the jets which are then burned by the flames... In most stoves, there is no direct heat being applied to the alcohol but there's enough radiant heat there to still cause expansion... In the case of THIS stove, the wick (inside the tubes) draws fuel up into the tubes, which is then SUPER-heated by the flames, hyper-expands the vapors and forces them back into the stove, which, in turn forces the vapors out of the jets at a greatly increased rate, giving it that "jet" sound.... A couple of problems I see with this design is (1) The increased pressure / heat generated by this design is going to exceed the JB Weld (glue) specs and probably fail very quickly... (2) The jet holes seem to be too small for the amount of pressure being forced through them which is right on the verge of blowing out the flames... I would either make the holes twice as big OR put 2 holes under each tube... Overall it's a good design (in theory), but that glue is going to fail and possibly be a dangerous situation... JB Weld is fine for use in stoves where there's no direct heat being applied to glued areas but this stove is purposely heating the copper which is only being held in place by glue... Be careful with that
You got it right John B, l would also question weather the JB weld would hold for any length of time under that heat, quick set 5 min. good for 230 deg. reg. JB high strength 24 hr set time 550 deg. l use a lot of JB great stuff.
I like this explanation but I still can't understand how the tubes create vapor that pressurizes the can AND draws fuel up the wick. Doesn't the rush of vapor out the tubes prevent fuel from being drawn up?
Have you tried using a silica wick in those? Im guessing regular wicks will get charred after some use. Silica wicks dont burn... They dont wick as good as cotton (at least for ecig juice), but its still pretty absorbant, and im guessing it would wick good enough for transporting alcohol pretty efficiently...
You can't go wrong when you use JB weld and they have different types of adhesive some may be more or less resistant to heat it depends on what type of epoxy you need to do the job 👍👍👍👍👍
its a pressure type stove. The three coils act as a heating element. As temperature increases, pressure builds up which results into pressurized ejection of alcohol. Its efficiency is increased because of the small diameter of the holes (the small ones in between the coil). If you check out "how to make Fancy Feast stoves", they'll explain why you have to make a pressure hole. That being said, since its just a stand alone experiment/demo, you'll have to make one (if you're bored) to compare boiling times with other types of alcohol stove.
@@beeeean I can't say much about it since I haven't made one but here's my take: Its effecient despite the hassle of the assembly required. It took this stove 5mins to boil water while it roughly takes 6mins to boil. Its worth the build as long as you have junk lying around. The U shaped copper coil is, what I think, the hardest part to look for. The only thing I know that has a U shaped copper coil is the refrigerator. This stove needs a cook stand that also acts as a wind barrier. Just like the one used in the video. If you put your pot on the coil, it could risk damaging the burner. This could be used as a secondary stove for boiling noodles and water. If you want to do quick fry, I think you'd have to increase the fuel capacity. The main drawback for this,IMO, is refueling between uses. You would wait for the burner to be cool to the touch to refuel or risk hurting yourself.
beware, glue copper coil will eventually explode. just had my explode on me, lucky no one was burned. Creator like such video need to at least warn viewer.
Great video, and you can stand your pot on the coils too. One question: what is the purpose of the wick? Will the heat burn the wick? Will the stove heat and boil the fuel without the wick?
so the wick essentially makes the propellant creep up it, getting it into the copper tube, which is then heated up from the fire, at that point it heats it up to gas state and has pressure forcing it out the 3 small holes causing the jet flame.
Lo hice pero solo salen 3 llamas débiles, estoy utilizando alcohol de 90, cuál puede ser el problema? Requiere mucho tiempo para ganar presión? Es normal que el recipiente que contiene el alcohol se caliente? Es peligroso que estalle?
No lee español. me parece. Pero sí que puede ser peligroso, luego de alentarse por un buen rato, es mejor usar poco alcohol mientras se prueba, y tomar precauciones, por si explota. Debemos esperar porque debe empapar las mechas, pienso.
If steel cans are used then the copper tubing can be silver soldered to it. This could potentially be scaled up a little in size to provide greater heating capacity. Used as an emergency radiant room heater or cooking for a family, this thing could be a game changer.
the most basic premise to understand is the pre-heating of the fuel. there was a heater used in the military back in the 40's that was nothing more than a circular tube of pipe with some holes in it near the end. the holes were aimed at the inner portion of the tube, the other end connected by hose to a diesel fuel drum.
Ya entendí el funcionamiento, al calentarse los tubos de cobre con las mechas húmedas de alcohol se gasifica y aumenta la presión y sale expulsado por las tres perforaciones minúsculas de 0,6 mm. Excelente vídeo, felicitaciones y saludos cordiales desde Quito Ecuador.
Really really nice!! Congrats my brother! I really want to make something like this now! Haha But I have to ask, how we "turn off" it? I need to wait it burn the whole alcohol inside it? If i just "kill the flame" doesn't will still letting the gas goes out of it? If there were some way to close the thin hole that let the gas out can it work to "turn off" the stove? Anyway, congrats for the nice project you have done!
Temperature rating of normal JB Weld is listed as 500F continuous, 600F for 10 minutes. I'd be willing to bet those copper loops are getting up pretty close to that!
@@aleehene Probably, I wouldn't be surprised to find it gives off toxic fumes when heated too. I would personally use silver solder or fire cement, though I doubt solder would bond to aluminium cans
Hd hd3 does that copper tubing has little tiny holes for the alcohol to jet spray? There will be no fire whatsover if theres no flamable outlet would it?
Good job... Please When you insert the small pease in the top large one... are you shuted it by soldering or by devicon or just close it titly... Warm regards
