Alcohol burner

An integral part of a camping trip, winter fishing or hunting is the preparation or heating of food. For many objective reasons, sometimes it is not possible to make a fire. Gas burners have proven themselves well in this case, but, with all the advantages, they have drawbacks: during the whole trip you need to carry a burner weighing about a kilogram, and at least two cylinders, which weigh on average 250 grams. If the trip is long, more cylinders will be needed. In addition, such travel devices are not cheap. A marching alcohol burner is well suited to replace a gas one: it weighs very little, the amount of alcohol necessary for its functioning can even be transported on an airplane, and you can do it yourself. In addition, a home-made alcohol burner is always useful in everyday life.

Alcohol can burner

Alcohol can burner

The principle of operation of an alcohol burner is the combustion of fuel vapor.

An alcohol burner from a can is made as follows:

  1. You will need two cans of canned food, coffee, etc., a piece of glass wool and fuel. Tin cans need to be well washed, dried. Then they need to be cut in half, a piece of glass wool put on the bottom of one of them. It is necessary to make a cap so that the cotton wool does not crumble, place on top of it.
  2. Holes are made in the bottom of the second can, put on top of the first. They should fit snugly against each other, there should be no gaps at the edges.
  3. In a circle of the upper can with an awl, you need to make holes with a diameter of 2 mm with a distance of 8 mm between them and 1.5 cm from the edge of the can. The holes should be made in such a shape that the metal is slightly bent up. You should get from 16 to 26 of these holes.
  4. Using a syringe and a tube placed on its nose, alcohol is poured into it so that glass wool or other material is saturated with it (you can put a regular pumice stone).
  5. Ignition is carried out as follows: an alcohol burner with its own hands is heated from below, where the fuel is, so that it starts to evaporate. After that, the lighter is brought to the holes on top, the alcohol vapor begins to burn.

Alcohol must be used at least 96% as fuel, it can be replaced with salicylic acid, streptocide. As practice shows, the intensity and duration of burning of an alcohol lamp depends on the type of fuel. The most intense combustion shows fuel from alcohol, and streptocide and salicylic acid are less intense, but at the same time they have a longer burning time than alcohol. It is impossible to use gasoline as fuel because of the risk of its explosion. Kerosene is also not suitable due to lack of wick. As a material for alcohol impregnation, it is better to use materials made from natural fibers.

Beer can alcohol burner

Numerous videos contain detailed instructions on how to make an alcohol burner from aluminum cans of beer or soda.

Alcohol burner from a beer can

To make an alcohol burner from beer cans, you need to do the following:

  • Take two aluminum cans, mark with a marker and a wooden block the cut line (about 3-4 cm from the bottom), cut.
  • Firmly insert one cut off part into another.
  • In the center of the upper can, make a hole with an awl for refueling. Close the filler hole with a bolt. Instead, you can use a coin. This item is even better: with overheating and high pressure, it simply jumps up, releasing the excess so that the jar does not explode.
  • Around the circle of the bank, approximately 16 pieces are pierced with holes with an equal distance between each other.
  • 25-50 ml of alcohol is poured into the filler hole, the hole closes. You can put cotton on the bottom, as described in the case of cans.
  • The spirit lamp is placed on a metal base (you can use a metal cover), onto which some alcohol is poured, set on fire.
  • After 20-40 seconds, the burner will warm up, flames will come out of the holes.

Alcohol burner

Do-it-yourself alcohol burner can be of two types: open and closed. The above describes the manufacturing methods of the second type. An open one differs from a closed one in that it does not have a top cover, and the fuel is ignited without preliminary heating. Minus the open spirit lamp: high fuel consumption. Minus of the closed burner: slow heating, lateral flames can be blown away by the wind, care must be taken when handling to avoid tipping over.


For proper use, you will need to make a stand for dishes. This is easily accomplished with ordinary wire. A support for the boiler and other utensils is necessary in the winter season, when cold dishes can extinguish the burner. If the burner without a stand is made of aluminum, it will only heat aluminum cookware efficiently.
