Dry fuel: types and methods of how to make it yourself

The need for making fire often arises in people who are fond of hiking and traveling. But there may be no trees nearby or the available wood will be damp. In this case, you must purchase dry fuel, which is easily flammable, burns from 5 to 30 minutes and is compact in transportation.

Dry fuel and its composition

Dry combustible known since 1860 thanks to the researcher chemist Butlerov. As a result of scientific work on the study of formaldehyde and ammonia, they were isolated colorless crystals, called urotropin, which became the basis of the composition of the first dry fuel. Now, for ease of use, manufacturers mix the substance with a small amount of paraffin and press into cylindrical tablets. In this form, the product reaches the buyer. In life, another term has spread – dry alcohol. However, the product is not related to alcohol.

Commercially available dry fuel tablets are based on other chemicals – metaldehyde and calcium acetate solvate.

Urotropin burns without the formation of ash. Easily ignited with a match. The flame quickly goes out when the air supply is cut off by covering it with a cap or a cup. The damp tablets on the basis of this substance emit a crack and burn out sparks when burned. Metaldehyde in the combustion process when interacting with air forms carbon dioxide and water vapor. Therefore, it leaves no decay products. The calcium acetate solvate in the reaction with ethyl alcohol hardens. The resulting mass is similar to soap. It can be cut into cubes and set on fire. After combustion of the substance remains ash.

Advantages and disadvantages

The product is easy to use, flammable, has a small volume, unlike other fuels. Compact and appreciated by lovers of hiking. Takes up little space in the backpack, easy to carry.

With a small volume, it is quite a powerful source of thermal energy. Dry fuel can heat food and boil water. It can be used as an ignition for a fire. Does not lose properties even in the damp state.

Dry fuel is an indispensable tool in a hiking trip.The disadvantages include the cost of dry fuel and the inability to control the strength of the flame. The amount of heat generated is always the same. Boil the soup or porridge at the tablet is not enough power. In addition, the fire is flimsy, sensitive. Extinguished with minor gusts of wind. Therefore, the use of fuel requires the construction of wind barriers.

Dry fuel, made on the basis of urotropine during combustion, emits caustic substances: formaldehyde, hydrogen cyanide and ammonia.
Toxicity of substances is not high when distributed in the open air. However, one should not specifically inhale the smoke generated during the combustion of the tablet. Metaldehyde may be harmful to health only if swallowed. The breakdown product of calcium acetate – hall. She is safe.

Types of dry fuel

The product market is represented by trademarks of Russian and foreign manufacturers. Hardware stores, pavilions, Internet kiosks offer the buyer a wide variety of dry fuels, each of which has distinctive features.

Pathfinder

The group of companies “Result” sells dry fuel “Pathfinder”. Products received by the consumer undergo a series of mandatory tests, produced on high-tech equipment with the participation of specialists – chemists. It is intended for lovers of outdoor activities on the outskirts of civilization, for anglers and hunters, gardeners and holidaymakers in country houses.

 The manufacturer suggests using pelletized fuel for lighting a fire, barbecues, stoves and for an independent source of heat.

The mass of one tablet is 15 g. (+/- 4). The burning temperature is 900 C. The combustion period is 10-12 minutes. Each tablet is protected by a compact sealed package. It is convenient to use, because when opening a general package, unused tablets are protected from moisture, will not collapse, will retain their shape and will not lose flammable properties. The pronounced sharp smell, characteristic of a dry fuel, does not spread to the environment.

Esbit dry fuel

Esbit preformed dry fuel is packed in 4 pieces in waterproof plastic sections. 4 sections are laid in a cardboard box of small dimensions. The weight of a box is 88 g. Compactness allows you to place it in a small backpack or a pocket of outerwear. Plastic sections provide protection from moisture. If the storage conditions are met, the fuel has no expiration date.

Esbit dry fuelThe weight of one tablet is 5 g. It is capable of producing enough heat to heat a portion of food not exceeding 250 g. For heating large volumes or boiling water, the simultaneous use of 4 tablets is recommended. Fuel is highly safe – when ignited and burning does not emit hazardous substances, smoke, sparks.

How to make dry fuel at home?

Buying fuel in the store is ideal. However, not all available due to the high cost. An alternative in this case would be making a dry fuel with your own hands.

In the first case, you will need 100 grams of biofuel – gasoline. 1 kg of foam (you can use the remaining packages of household appliances). Metal container with a diameter at the base of 15 cm and a depth of 5 cm. Wooden stick for mixing.

Stages of cooking:

  • gasoline is poured into the tank;
  • the foam is crumbled into pieces (the volume of foam should correspond to the volume of gasoline);
  • connect components;
  • Stir the mixture slowly with a stick for 15 minutes.

Gasoline eats foam. Formed mass of consistency similar to the steeply kneaded dough, easily taken in any shape. The finished substance is rolled into a ball, wrapped in plastic bags. As necessary, you need to pinch the required amount of fuel and use as directed.

The second version of the manufacture of dry fuel at home will require the availability of: cotton pads, paraffin, metal container (can) and tweezers.

The second version of the manufacture of dry fuel at home will require the availability of: cotton pads, paraffin, metal container (can) and tweezers.

  • In a can, over a slow fire, melt 20 g of paraffin. Remove from heat.
  • Tweezers capture three cotton discs stacked in a pile.
  • Cotton discs are dipped into uncured paraffin and incubated for 5-10 seconds.
  • Dry out the impregnated discs to dry.
  • Burning time 1 paraffin tablets 10 minutes.

    Consider how to make dry fuel from hexamine at home.

    1. Enameled pan with a capacity of not more than 5 liters put in a bowl of cold water.
    2. Pour into a container of 100 g of formalin.
    3. A thin stream, portionwise added to formalin 1 l of ammonia.
    4. Stir the ingredients, close the lid and leave alone for a day.

    The procedure is done in the open air. A chemical reaction that takes place during mixing releases toxic fumes.

    After a day, the contents of the pan are evaporated in a water bath to obtain crystals. The substance resulting from the labors of the house chemist is the same urotropin. It can be applied in powder form or grind with paraffin and form tablets.

    Self-made fuel is recommended to be stored in packed form in places inaccessible to children, far from open flame. The temperature in the room should not exceed + 15C.
