In the previous article, we talked about stoves based on the effect of pyrolysis (combustion of gases). Pyrolysis can be successfully used for organizing disposable stoves directly from fuel - wooden logs and logs 40–80 cm in size.

The described option has advantages:

• the ability to cook / reheat food without additional (iron) devices, except for a kettle or frying pan;
• profitability - one log burns for 3-4 hours;
• good light;
• quick organization - no need to collect thin firewood.

Along with the advantages, there are characteristic disadvantages:

• need exactly sawn-off lumps or logs;
• in some cases a saw or wire is needed;
• disposable oven.

In the future, the advantages and disadvantages will be given in relation to other varieties. People call such a vertical fire a "candle".

Method number 1. Finnish candle

This option is suitable if you can use a chainsaw. The chock needs to be sawed, dividing the cut circle into equal parts, ideally 6 parts. Do not make the cuts to the end, so that an untouched section of the tree ("bottom") remains. Then split the core with an ax, add fuel and lubricants (oil, gasoline, diesel fuel) and set it on fire.

Benefits:

• manufacturing time - 10 minutes, you can make several "candles" in one hour;
• safety - the bottom will not allow dry grass on the ground to ignite;
• the fire does not damage the soil even after complete burnout;
• high bright flame;
• gives a lot of warmth and light;
• portable design.

Disadvantages:

• burns out quickly (2.5–3 hours);
• difficult to ignite;
• need a chainsaw.

Method number 2. Finnish candle-2

The chop should be split into 4 equal pieces to make equal logs. They must be installed in their original form (in the form of a chock) and ignited in the middle. You can pick up a tree from a woodpile.

In fact, it is a reduced copy of the three-log oven. The principle is the same, the advantages and disadvantages are the same.

Method number 3. Three logs

Universal vertical disposable long burning oven. To organize the hearth, only three adjacent chocks are required. Then you just need to make a fire inside the formed well. After burning, the chocks can be moved closer to the center. This type of wooden stove combines all the advantages, practically without any disadvantages.

Benefits:

• simplicity of the device - no need to additionally prepare the material;
• optimal balance of light and heat;
• burning time without adding fuel - up to 7 hours;
• sustainability.

Disadvantages:

• less resistance to wind;
• the logs must be evenly split.

Method number 4. Primus

The most perfect and convenient way to organize a log oven. It gives a high concentration of flame and can be made in a “mini-version” with a height of 20–30 cm. In order to organize a “Primus”, you will need several logs, and not necessarily from one block.

Operating procedure:

Cut off a block of a given size.

Divide it into 4–6 parts with an ax or a saw, or select suitable logs.

We gouge out the core and make notches (shavings).

We connect the logs with wire so that a "well" is formed inside. If the logs are large, you can make 2 of them shorter than the rest. This will provide oxygen for the pyrolysis during the installation of the pot or pan.

The cold hearth before kindling should look like this:

We load the shavings into the free space inside the stove.

We set it on fire and use it. Pay attention to the flame - pure pyrolysis combustion.

Larger options can be used for general purposes.

The optimal length of a log (lumps) is two of its diameters. The ability to cook food, boil water is available for the first 2 hours after lighting, until the logs burn out.

How a disposable oven can be useful on the farm

The main property of a wooden stove is combustion of pyrolysis gases, which makes it an effective reactor when creating a stove in the yard, barbecue, cauldron or barbecue. A concentrated flame can be used for heating and roasting metal or slaughtered poultry - pyrolysis combustion for 2-3 hours is a lot. A dense flame will melt cold lumpy bitumen or roofing felt many times faster than a regular fire, and replace a propane burner (portable version) in an upright position.

The principle of organizing the stove "Finnish candle" described above is an economical and convenient way to heat and create an impromptu camp or courtyard kitchen. He will be able not only to save time and effort, but even save lives in the event of an unforeseen stay (overnight stay) in a remote area.
