Secrets of long-lasting operation of solid fuel units

The method of adding fuel to a long-burning burzhuyka conceals its entire secret. Since the firewood in this type of stove is lit from above, there is no risk of all the logs placed in the fuel chamber burning at once.

Even with its simple appearance, a long-burning heater made at home can hold its own against many wood stoves manufactured in factories.

Furthermore, the air supply method facilitates this. Only the top layer of fuel receives the oxygen required for combustion. With these solutions, the tab’s size can be increased to the extent that the furnace’s capacity permits. Naturally, these units have ten times longer continuous operation times.

The effective combustion of fuel is the key to long-burning stoves.

The solid fuel pyrolysis process, which occurs at high temperatures and in an oxygen-free environment, extends the heating cycle’s duration. Instead of burning, the wood smolders and releases a significant amount of volatile hydrocarbon compounds. Heat is released in large quantities when pyrolysis gases burn beneath the stove’s vault. Smoldering thus helps to extend the duration of continuous combustion, and pyrolysis enables you to multiply the heat generator’s efficiency.

Bubafonya is an additional long-burning stove variant. It is something you can prepare at home. A schematic diagram and detailed installation instructions can be found in our upcoming article at https://aqua-rmnt.com/otoplenie/bubafonya-svoimi-rukami.html.

The design and principle of operation of a long-burning stove

The design of the bubbafonka, which we offer for manufacture, successfully implements the above-described methods of extending the furnace’s continuous operation time. The device is characterized by its remarkable simplicity and small number of parts, which doesn’t stop it from successfully competing with more sophisticated heating devices.

Firewood is put into the body, which is most often made in the form of a cylinder. The fuel is pressed on top by an air distributor in the form of a hollow rod with a piston (a heavy metal disk with a hole in the center for air supply). Support vanes (blades) are welded to the bottom of the steel pancake, the width of which determines the height of the gap between the fuel and the piston. In other words, the volume of the combustion chamber depends on the size of the blades. A pipe is welded to the back side of the disk, through which air enters the furnace. To regulate the amount of air, the channel can be completely or partially closed by means of a sliding damper.

The layout and basic functioning of a long-burning wood stove

The spigot for connecting the chimney is cut into the upper portion of the firebox housing. A minimum of 4 meters should be the height of the pipe to guarantee normal thrust. A lid with an opening for the air distributor covers the top of the device.

Primary air is supplied directly under the piston, which divides the working space into two chambers. Precise dosage of oxygen makes it possible to reduce the intensity of the flame, facilitating the transition to the gas generation mode. At the same time, heat energy is released not only by burning fuel, but also by pyrolysis gases, which are actively afterburning under the lid. Secondary oxygen for their oxidation is supplied through a special window in the upper part of the stove, and in the simplest case – through a gap between the air supply pipe and the top lid. After burning the top layer of firewood, the metal disk under its own weight descends, providing access to oxygen to a new fuel horizon.

Through a chimney carved out of the upper body, combustion products are expelled from the stove. The chimney is connected to the heater via a tiny horizontal passage that functions as an air heat exchanger in order to maximize the heat output even further.

What you will need for the work: tools and materials

In a matter of hours, this "long-lasting" stove model can be constructed. To achieve this, all you need is a strong desire and well-organized work process. It will also be essential to fully comprehend the unit’s design and make all necessary preparations beforehand.

From the necessary tools:

• welding machine – best for this purpose is a small, lightweight inverter with the ability to adjust the current up to 200 A;
• Angle grinder (in common parlance grinder or "bolgarka");
• cutting and grinding disks, designed for work on metal;
• drilling machine or electric drill;
• set of drills;
• A hammer with a medium-sized striker;
• blowtorch;
• chisel;
• sledgehammer;
• tape measure and metal ruler;
• core (a device designed for marking, facilitating drilling);
• a scribbler for marking on metal surfaces.

Regarding supplies, it’s not necessary to adhere to the list precisely. The whole appeal of handcrafted structures lies in the fact that they can be made with any iron that’s lying around the workshop or in the backyard.

Any large container, like an unnecessary metal barrel, can be used to create the furnace’s body.

Thus, the inventory of required materials:

• steel pipes with a diameter of 80 to 250 mm, which will be needed to make the riser air supply and chimney;
• a suitable metal container with a diameter of 300 to 600 mm with a wall thickness of at least 2.5 mm (you can use a used gas cylinder, a barrel of fuel or a piece of pipe at least 120 cm long);
• metal sheet with a thickness of at least 4-5 mm, from which the air distribution piston will be made;
• sturdy metal hinges, which will be needed to fix the furnace and ash door;
• asbestos cord (it is necessary for sealing the loading window and other operational openings);
• angles with a shelf from 50 mm, channels and profile pipes – for the manufacture of air distributor blades, support legs and other structural elements;
• round metal pancake with a thickness of at least 5 mm and a diameter of 120-150 mm (you can take any suitable gear or sprocket from the automotives);

Preparing sheet steel with a minimum thickness of 2 mm and spigots to connect the liquid circuit to the heating (hot water supply) mains is also required if the heater is intended to have a water jacket. The pistons are also needed to put together a bourzhuika with a water circuit.

How to properly design a long-burning stove: schemes and drawings

You can use any appropriate container as the pyrolysis combustion stove’s outer casing. By utilizing waste materials, it will be possible to obtain a heating device for almost nothing. All that’s left to do is plan the other components of the building according to the specifications of the chosen housing. This will enable the construction of an affordable, efficient, and productive furnace.

You can use a special scheme to find the dimensions and parameters that influence the burzhuika’s operability and thermal efficiency. You must measure the diameter (D) and height (H) of the discovered tank in order to perform a computation based on its measurements. These will be the heater’s external parameters.

Depending on the size of the base, the long-burning burzhuyka’s calculation scheme will help to modify the component parameters.

Whole calculation process:

1. The ratio of the diameter (D) and height (H) of the stove should be within 1:3(5). In a too narrow and high stove, the afterburning zone of the combustion products will be stretched in height, which means that part of the gases will not be able to ignite in time and will simply escape into the chimney. If you build a low and wide unit, then the surface combustion will be too uneven. Air is supplied to the middle part of the stove, so the fuel will burn much faster there than at the edges of the stove. This will lead to the formation of a depression in the center of the pellet stove and the piston will hang on the unburned residues at the walls. In this case, normal operation, and even more so pyrolysis combustion, is out of the question.
2. The durability of the heater depends on the thickness of the metal (Δ) required for manufacturing the casing. A container with walls of 4-5 mm is best suited for this purpose.
3. When calculating the air distributor, it is important to correctly determine not only the diameter, but also the thickness of the piston. The massive part will glow and actively heat the air entering the combustion zone, which will have a positive effect on the performance of the stove. In addition, the thin disk will not press tightly against the upper plane of the tab, and this will lead to an increase in the air gap and uneconomical fuel consumption. A too heavy piston, on the contrary, will tend to reduce the gap. Excessive sealing of the fuel can lead to a complete extinguishing of the bourzhuyka. The situation is further complicated by the fact that the weight of the metal pancake depends not only on its thickness, but also on its diameter. Consequently, the larger the piston will be, the thinner the metal is taken for its manufacture.

Finding the ideal ratio between piston diameter and piston pancake thickness will be made easier with the use of the piston thickness calculation table.

Standard stoves can use the table to determine the blades’ parameters.

Naturally, it is not required to pay attention to the measurements of every component on the stove. They can be rounded in any direction without repercussions. The size of the gaps and transition holes affects how well the heater operates. These specifications have to match the computed values exactly.

For a bubbler that has a diameter of 450 mm or more, there is no need to install a firebox door because the unit can simply be filled with wood through the stovetop. If the body is going to be used as a gas cylinder, the challenges in operating it will come more from cleaning the ash heater than from laying fuel. It will be required to install an ash pan door in order to guarantee that the long, narrow container does not cause any inconvenience during operation.

To avoid creating a gap when cleaning the stove, you can use a slanted disk that is lowered to the stove’s bottom. You can remove the ash-filled container with ease thanks to a steel bar that has been welded to its center. The metal rod is passed through the air supply pipe after the ash pan is installed on the bottom, so it doesn’t affect the stove’s functionality in any way.

With the use of schemes and drawings, you can precisely ascertain all the heater’s design parameters and construct an efficient burzhuyku out of any appropriate container. It is sufficient to follow the proportions between each element of the design; precise measurements are not required.
