Garage for many car owners is not just a place to store a car, but a real workshop and recreation area. However, in the cold season to be in an unheated room becomes uncomfortable, and the start of the engine requires preliminary warming up. The solution to the problem is the installation of an effective heating system, and one of the most popular models is deservedly considered to be the most popular. baulerian. This type of heating equipment has proven to be a reliable and cost-effective option for rooms with a capacity of 30 to 100 cubic meters.
The principle of operation of such a boiler is based on gas generator combustion of fuel, which allows you to obtain the maximum amount of heat with minimal consumption of firewood or briquettes. Unlike the classic bourgeois, which cool down quickly, the Boulerian is able to maintain a set temperature for 8-12 hours on a single bookmark. It is important to understand that for safe and efficient work baulerian requires competent calculation of power and compliance with the rules of installation of the chimney.
In this article, we will analyze in detail the technical features of the design, compare popular models and consider the step-by-step installation process. You will learn how to correctly calculate the power required for your room and what nuances should be considered when choosing fuel. The efficiency of the boulerian reaches 75-80%, which is much higher than the performance of conventional metal furnaces of direct combustion.
Principle of operation and design features
The design of the boulerian is a cylindrical combustion chamber, braided with large diameter metal pipes. These pipes, welded to the body at an angle, play a key role in heat exchange. Cold air is sucked into the lower holes of the pipes, heated from the walls of the furnace and exits through the upper pipes already hot. This process ensures rapid circulation of air masses and uniform heating of the entire volume of the garage without the use of additional fans.
The furnace operates in two modes: intensive heating and gas generation. In the first case, the flap was blown open completely, providing a rapid increase in temperature in the room. In the second mode, oxygen access is blocked, and the fuel begins to smolder, releasing combustible gas, which burns at the top of the furnace. Exactly. gas-generation It allows the furnace to operate on a single bookmark for up to 12 hours, saving fuel.
The body of the device is made of heat-resistant steel with a thickness of 4 to 6 mm, which ensures the durability of the structure even at high thermal loads. The combustion chamber is divided into two parts: the lower, where solid fuel is burned, and the upper, where pyrolysis gases are burned. The tightness of the system is ensured by a tightly closing door with a reliable latch lock.
Why are the pipes welded at an angle?
The pipes are welded at an angle of 15-20 degrees to the horizon to create natural traction. Hot air is lighter than cold air, so it tends upwards, creating a discharge at the bottom of the pipes and tightening new portions of cold air.
It should be noted that the efficiency of the work directly depends on the quality of the fuel and the correct setting of the air supply. If you use raw firewood, the efficiency of the system will drop sharply, and a thick layer of creosote is formed in the chimney. Therefore, bulerian It is recommended to use dry wood or fuel briquettes.
Advantages and Disadvantages of Garage Use
Choosing heating equipment for the garage, you need to weigh all the pros and cons. Bulerian has a number of undeniable advantages that make him a leader in his class. First of all, this is a high rate of warming up: warm air begins to enter the room after 5-10 minutes after ignition. The system also does not require a permanent human presence, as fuel can be laid down for the entire night or work day.
- 🔥 Economics: Fuel consumption is lower by 30-40% compared to conventional direct combustion furnaces.
- 💨 Uniformity: Convection pipes provide air circulation, eliminating cold zones near the floor.
- 🛡️ Safety: The outer walls of the case do not turn red, which reduces the risk of burns and fire of nearby objects.
- 🪵 Universality: the ability to burn with wood, briquettes, cardboard waste and wood pruning.
However, this system has its shortcomings, which you need to know in advance. The main disadvantage is the need for a high-quality insulated chimney. Without sufficient thrust, the gas generation process will not start, and the furnace will simply smoke. It is also worth considering that the bottlerian is not designed to connect to the water heating circuit in the standard version, although there are models with a water jacket.
The main advantage of the bottlerian is the ability to maintain heat for a long time on one fuel stack, which is ideal for a garage where there is no possibility to constantly throw firewood.
Another important aspect is condensate. Fuel combustion produces moisture, which, combined with low temperature at the beginning of the fire, can flow back into the furnace or flow through the blower. This requires periodic cleaning and proper setting of the combustion mode. Ignoring this point can lead to corrosion of the metal and rapid failure of the furnace.
Power calculation and model selection
The right choice of power is the key to a comfortable temperature in the garage. If you take a too powerful stove, the room will be unbearably hot, and the fuel will be used inefficiently. A weak model, on the contrary, will not be able to warm up the volume of air, especially if the garage is poorly insulated. Standard calculation is made based on the volume of the room: 1 kW of thermal energy is able to heat about 20-25 cubic meters of well-insulated space.
For a garage of standard size (for example, 4x6 meters with a ceiling height of 2.5 meters), the volume will be 60 cubic meters. Taking into account the heat loss through the gates and walls, it is recommended to take a model with a power reserve. There are various modifications on the market, such as Bulerian Type-01 (up to 100 m3), Type-02 (up to 200 m3) and more powerful industrial variants. For most private garages, the best choice will be a model with a capacity of 6-9 kW.
| Model oven | Volume of premises (m3) | Power (kW) | Chimney diameter (mm) |
|---|---|---|---|
| Boulerian. | 100 | 6 | 120 |
| Boulerian 01 | 200 | 9 | 120 |
| Boulerian 02 | 250 | 12 | 150 |
| Bulerian 03 | 400 | 18 | 150 |
When choosing, also pay attention to the thickness of the metal furnace. For a garage where the oven can work daily and for a long time, it is better to choose models with a wall thickness of at least 5 mm. Thin-walled variants (3-4 mm) burn out faster and deform with frequent overheating. It is also worth checking the quality of welded seams and the reliability of fittings.
Installation and fire safety requirements
Installation baulerian It requires strict compliance with fire safety regulations. Garage is a room of increased fire hazard due to the presence of fuel, rubber and plastic. Therefore, the distance from the furnace body to the nearest combustible objects should be at least 1 meter. If the walls of the garage are made of wood or sheathed with combustible materials, it is necessary to install a protective screen of non-combustible material.
⚠️ Warning: Installation of a stove on a wooden floor without additional protection is strictly prohibited. Be sure to use a metal sheet or tile base, protruding beyond the dimensions of the furnace at least 50 cm in front and 30 cm on the sides.
Particular attention should be paid to the chimney. To ensure good traction and prevent condensation, it is recommended to use sandwich tubes. The height of the chimney should be at least 3 meters from the collapsible grille, and above the roof ridge - rise at least 0.5 meters. All joints of pipes must be sealed with heat-resistant sealant, withstanding temperatures up to 1000 ° C.
☑️ Installation safety check
A ventilation system must be provided in the garage. The oven burns oxygen, and with a lack of fresh air, the thrust can worsen, and the combustion products can get into the room. For normal operation of the bottlerian requires an air inflow of at least 10 m3 / h per 1 kW of power.
Installation of the chimney with their own hands
Installation of the chimney is the most important stage of installation. Mistakes at this stage can lead to smoke in the garage or even a fire. The assembly begins from the nozzle of the furnace, moving upwards. It is important to remember the rule: the inner pipe is inserted into the lower one so that the condensate flows down to the furnace, and not outward. For this purpose, special tees with condensate traps are used.
Passage through the roof or wall must be made with observance of fire breaks. If the chimney passes through a wooden wall or overlap, a passage assembly with a non-combustible filler (basalt wool) must be used. The distance from the pipe to the combustible structures must be at least 380 mm (for single-wall pipes) or 250 mm (for sandwich systems).
Assembly sequence:1. Installation of the starting element on the furnace.
2. Installation of the first section of the pipe (single-walled).
3. Installation of a tee for cleaning and draining condensate.
4. Switch to the sandwich tube.
5. The pipe rises above the roof ridge.
6. Installation of a deflector or weather vane.
To increase traction and prevent precipitation on the head of the pipes install a deflector. This is especially true for garages located in the wind zone or surrounded by tall buildings. Regular cleaning of the chimney (at least 2 times a season) will help to avoid overgrowth of soot and reduce efficiency.
To seal the joints of pipes, use heat-resistant sealant (up to 1500 ° C) and crimping clamps. Regular silicone will burn out when heated, and the system will lose its tightness.
Fuel and operating rules
The efficiency of the bulerican directly depends on the fuel used. The ideal option is dry wood hardwood (birch, oak, aspen) with a humidity of no more than 20%. Coniferous rocks contain a lot of resin, which settles on the walls of the furnace and in the chimney, forming a hard-to-remove plaque. Wood briquettes, pellets or woodworking waste can also be used.
It is strictly impossible to burn coal, coke or liquid fuel in a boulerian. The high burning temperature of coal can lead to burnout of the metal furnace, and liquid fuel will cause uncontrolled ignition and explosion of vapors. Mode of smolderingThe fuel that runs the stove is not designed for such fuels.
The stove should be started with small chips and paper, gradually adding larger logs. When the furnace warms up and there is a stable thrust, you can transfer the furnace to the gas generation mode, covering the blown valve. The optimal position of the flap is selected experimentally: the flame should be smooth, without black smoke, but also not flash with open fire.
⚠️ Note: Do not use gasoline, kerosene or other flammable liquids to ignite. This can lead to a volumetric explosion in the furnace and damage to the furnace or injuries to the operator.
Care for the oven is to regularly clean the ash (although ash is formed a little) and remove soot from the heat exchanger pipes. Once a year, it is recommended to conduct a complete audit of the chimney and check the tightness of the connections. With proper operation baking It lasts 10 years or more, providing stable heat in your garage.
Frequently Asked Questions (FAQ)
Can you burn a bottlerian with coal?
No, you can't burn the Boulerian with coal. The design of the furnace is designed for pyrolysis combustion of wood. Coal gives too high a temperature, which will lead to deformation and burnout of the furnace walls, and can also disrupt the gas generation process.
How often should the chimney be cleaned?
The cleaning frequency depends on the quality of the fuel and the operating mode. When using dry firewood and properly adjusting the thrust, it is enough to clean the chimney 1-2 times in the heating season. If raw fuel or needles are used, cleaning may be required more often.
Do you need electricity to run a bottlerian?
The classic boulerian is energy-independent and works by natural traction. However, there are models with a built-in fan (convector) that requires a connection to the power grid to force air circulation.
What is the optimal chimney diameter?
The diameter of the chimney must strictly correspond to the diameter of the furnace output pipe specified in the product passport. It is usually 120 mm or 150 mm. Reducing the diameter is unacceptable, as this will lead to deterioration of traction and smoke.
Can I connect the bottler to water heating?
A conventional air bottler is not designed to connect to a water system. For this purpose, there are special models with a water jacket (hydraulic boulerians), which are structurally adapted to work with a coolant under pressure.
