The Breneran or Buleryan stove is a highly efficient small-sized device for heating, which is produced by Canadian, German and Russian companies. It vaguely resembles a classic potbelly stove, but has its own advanced characteristics and high efficiency. Furnaces of this type are mass-produced; the model range varies in power and design. You can make a Breneran oven yourself. The choice of product depends on the area of the room and its purpose, space allocated for the furnace, cost estimates and necessary functions.
Description of the Breneran furnace
Buleryan stove is a development of the German company Bulerjan, which is engaged in the production of heating equipment. By the name Breneran they mean the same devices, but created by Russian companies under license.
Characteristics:
- There is a flat platform at the top. Used to warm food.
- The shape is cubic instead of the usual cylindrical.
- There is an ash pan, as well as a grate.
- Convection heat exchangers are recessed into the housing.
Initially, the product was conceived as a stove with an air heat exchanger, but its feasibility is not justified. The heat capacity of such a device is low, which reduces the efficiency.
To save heat, owners use different storage devices for convection pipes. They can also be placed in brickwork, forming a kind of fireplace. This is a variant of the Breneran sauna stove.
Currently, the Breneran boiler is actively used in the following areas:
- heating of cottages and houses;
- production workshops;
- garages;
- baths;
- cafes and restaurants;
- administrative buildings in small towns.
When choosing and installing the boiler, power, dimensions, installation location and other parameters are taken into account. They affect the efficiency and uniformity of space heating.
Firewood, bark, chips, wood shavings are used as fuel. It is not advisable to choose coal as the raw material in the original furnace, since deformation of the body can occur from high temperature. You can get around this ban by upgrading the device. It is necessary to make a collector in the lower part of the heat exchanger and to supply air with the help of a supercharger.
There are two varieties: a Breneran boiler with a water circuit and a Breneran gas generator furnace. The first type works from water heating at home, and the second from gas. Also, gas generating devices often have a place for cooking.
Design features and working principle
The Breneran stove from Canadian experts has the design of a convection boiler for long burning. They enlarged the furnace doors, made another form of blowing in the form of a nozzle, and put a throttle inside to control the air level. To control the power of the furnace, a lever is used that controls the choke.
A firebox is a metal cylinder that has tubular heat exchangers on both sides. They are curved in the form of knees. Due to the fact that most of the pipe is in the furnace body, the air receives up to 70% of the heat from the wood. This allows you to heat the air to 100 ° C at an oven temperature of 60 ° C.
The furnace is divided into three chambers. The grate or under metal is installed in the lower part. A metal sheet is mounted under the firebox arch. Volatile compounds are burned in the upper chamber.
Combustion products are discharged through a special hole in the afterburner.At the beginning of the chimney, a damper with a 90 ° sector is made. To select the correct traction around the metal plate, which is engaged in its adjustment, a gap is made. It is equal to 10-15% of the diameter of the chimney.
Original furnaces also have a device for pyrolysis combustion of gases - an economizer. It is installed near the exit opening in the horizontal section of the chimney. So that the combustion products have time to cool, the pipe must have an optimal height.
Advantages and disadvantages
The positive sides of Breneran include:
- Mobility. The product has compact dimensions, therefore it is convenient to transport.
- Compactness. The configuration of the furnace allows you to put the device in small temporary buildings.
- Safety. This is achieved due to the tightness of the working chamber and the use of a scheme with one door. There are also obstacles to accidentally touching hot metal parts.
- High performance. The room is heated as soon as possible due to forced convection.
- The possibility of long-term functioning. The Breneran bath stove can work for several hours from a single fuel load.
- Easy operation and high reliability.
The disadvantages include achieving high performance only when using completely dry firewood. Humidity of more than 10% reduces the intensity of combustion and reduces efficiency. Also, the stove does not keep heat well. After burning fuel, the room temperature decreases. To increase work efficiency, it is also important to make additional thermal insulation of the chimney.
Operation and maintenance of the furnace
In order for the Breneran oven to work efficiently, the operating conditions must be observed and the heater properly maintained.
The main tips that experts give:
- You can only heat with dry finely chopped firewood. Under them lay paper or cardboard.
- It is not recommended that the oven be fully open for more than 30 minutes. Breneran is designed for smoldering fuel, because of which part of the thermal energy can go away.
- After complete burning of firewood, the stove goes into gasification mode. To do this, shut off the gate and throttle.
If the potbelly stove is filled with smoke, one of the following errors can be judged:
- Low chimney height. Optimum performance is provided by a pipe 5 meters high.
- Slide shutter closed.
- The smoke channel is clogged with soot. It must be cleaned. Preventive cleaning is carried out once a year.
Pollution of the furnace worsens its draft, which reduces heat transfer. For cleaning, you can seek help from specialists.
Popular models
At the moment, there are several popular models of the Breneran brand:
- Breneran AOT-14. This is one of the largest furnaces, capable of heating an area of 400 sq.m. Made from steel. It can work for 10 hours. It is used for heating cottages and country houses.
- Aqua Breneran. Heating is due to the circulation of the fluid and its heating. Suitable for heating large areas, workshops, workshop. Operating time from one bookmark of fuel 6-8 hours. There is a water tank.
- Breneran AOT-08 type 005. It allows you to cook and heat the house. A gas generator is suitable for heating small rooms.
- Aquaten. This is a unique furnace with a different design. Her pipes are connected to heating batteries, through which the coolant flows. Made of high strength steel. Instead of fuel, a heater with a power of up to 1 kW can be used to operate the Aqua Breneran boiler.
The choice of a suitable model depends on several criteria: the area of the room, which affects power, type of fuel, dimensions, necessary functions.
If you have the skills and professional equipment, you can create an oven yourself according to the instructions. Also, a home master can upgrade it with his own hands.
