How to make an eternal log in the oven. Do-it-yourself wooden stove or disposable wood burner

Despite the emergence of new types of boilers and stoves, wood heating remains relevant for the heat supply of cottages and small houses. The efficiency of its operation and fuel consumption depend on the correct organization of the system. But besides this, it is important to know how to heat your stove or boiler with wood so that the house is warm.

What determines the heat transfer of a wood stove

The heat transfer of the heating system depends on several factors: the design of the stove and its condition, the quality of the firewood and the degree of thermal insulation of the house. These parameters are calculated even before the organization of heat supply. But often they need to be optimized for the existing system.

  • minimize heat loss at home: insulate the outer walls and roof, install new windows with a low heat transfer rate;
  • make preventive maintenance of the furnace: make sure the integrity of the furnace and ash pan, install a heat-insulating layer from the side of the outer wall;
  • prepare firewood: choose the right type of wood, form logs of the optimal size, dry them.

These actions must be done before the start of the heating season. In this way, you can avoid additional heating costs and maintain a normal temperature level in the house with minimal effort. But the most crucial moment is the preparation and proper use of fuel.

Stoker's secrets: how to use firewood economically and efficiently

The first step is to choose the optimal wood. “Solid” varieties are best suited for wood heating - oak, walnut or birch. These logs have maximum heat dissipation. But the choice is not always possible and often the available species are used - hardwood or pine. The latter contains a large amount of resins, which in the process of burning will form a layer of soot inside the chimney.

To prepare for the winter season, you need to do the following:

  • prepare firewood - chop into logs and dry them;
  • organize a place for their storage - a canopy or a separate room;
  • make a place for drying near the stove - the next batch of firewood should contain a minimum of moisture.

These steps need to be considered in more detail.

Log preparation

During the preparation of firewood, the optimal size of the logs should be calculated in advance. They depend on the dimensions of the furnace. The length of the logs should be 3-4 cm less than the same indicator of the combustion chamber. The diameter of the firewood is usually 9-11 cm. If it is larger, the core will not burn out. To solve this problem, you will need to constantly knock ash off the logs.

During preparation, you need to pay attention to the following nuances:

  • the absence of foreign objects in the wood - nails, metal staples;
  • knots have a higher density and burn worse;
  • wood shavings are not recommended for use as fuel.

An important point is the correct storage of logs. Air gaps should be formed between them to remove moisture. The woodpile is protected from atmospheric precipitation by a canopy. Its dimensions should be 20-30 cm larger than the dimensions of the stacked firewood.

Furnace Prevention

The next step is to optimize the parameters of the heating system. In order to keep the house warm when heating with wood, preventive work should be carried out. The integrity of the structure is checked, if necessary, the old masonry is dismantled and a new one is installed. The design capacity of the structure must correspond to the actual need.

Types of preventive work with a wood-burning stove:

  • cleaning the ash pan, combustion chamber and chimney from soot;
  • checking the gaps of the grate, if necessary, they are replaced;
  • doors must close tightly;
  • if moisture forms on the inside of the chimney in winter, it is insulated.

The last factor is very important. The condensate flows into the combustion chamber and reduces the efficiency of the wood stove. It also provokes the rapid formation of a layer of soot in the chimney and a decrease in its working diameter, which will affect the thrust indicator.

Laying and maintaining the flame

Stack firewood in the combustion chamber should be loose. There should be gaps between the logs for air supply. In terms of height, firewood should not occupy the entire volume of the firebox. Air draft is the circulation flow between the ash pan and the chimney. Therefore, there should be space between the firewood and the grate. To do this, it is recommended to put one log across the entire masonry at the bottom of the firebox.

  • Traction adjustment. The maximum air flow should be only at the time of kindling. When the flame is stable, reduce the draft by closing the ash pan door.
  • The combustion chamber door must be closed at all times.
  • After burning the top layer of firewood, it is recommended to bring down the soot so that the rest of the wood burns out.
  • Periodic cleaning of the ash pan.

Guided by these simple rules, you can heat the stove with wood correctly, and the house will always be warm and cozy. It is important that the heat transfer is not more than required. Otherwise, fuel consumption will increase and, as a result, heating costs will increase.

The article contains an interesting and effective way to organize the hearth with the help of logs. The article presents different ways of arranging a vertical combustion furnace from logs. You will also find photo instructions for creating a wood burner with your own hands.

In the previous article, we talked about furnaces, which are based on the effect of pyrolysis (combustion of gases). Pyrolysis can also be successfully used to organize disposable stoves directly from fuel - wooden logs and logs of 40-80 cm.

The described option has advantages:

  • the ability to cook / warm up food without additional (iron) devices, except for a pot or pan;
  • efficiency - one log burns for 3-4 hours;
  • good light;
  • speed of organization - no need to collect thin firewood.

Along with the advantages, there are some characteristic disadvantages:

  • exactly sawn off chocks or logs are needed;
  • in some cases, you need a saw or wire;
  • oven disposability.

In the future, the advantages and disadvantages will be given relative to other varieties. In the people, such a vertical fire is called a "candle".

Method number 1. Finnish candle

This option is suitable if you can use a chainsaw. The chock needs to be cut, dividing the cut circle into equal parts, ideally 6 parts. Do not make 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 fire to it.

Advantages:

  • 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 heat and light;
  • portable design.

Flaws:

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

Method number 2. Finnish candle-2

Chock should be split into 4 equal parts to get equal logs. They need to be installed in their original form (in the form of a chock) and kindled in the middle. You can pick up a tree from a home woodpile.

In fact, this is a reduced copy of the “three logs” stove. The principle is the same, the advantages and disadvantages are similar.

Method number 3. Three logs

Universal vertical disposable long-burning stove. To organize the hearth, only three adjacent chocks are required. Then you just need to make a fire inside the formed well. After burning out, the chocks can be moved closer to the center. This type of wooden stove combines all the advantages, with virtually no drawbacks.

Advantages:

  • 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.

Flaws:

  • less resistance to wind;
  • logs should be evenly split.

Method number 4. Primus

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

Operating procedure:

We cut off the chock of a given size.

We divide it into 4-6 parts with an ax or a saw, or we select suitable logs.

We cut out the core and make notches (chips).

We connect the logs with wire so that we get a “well” inside. If the logs are large, you can make 2 of them shorter than the rest. This will provide oxygen for pyrolysis while setting up the pot or pan.

A cold hearth before kindling should look like this:

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

Burn and use. Pay attention to the flame - in its purest form, pyrolysis combustion.

Larger variants can be used for general purposes.

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

How a disposable oven can be useful on the farm

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

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