Design features and principle of operation of Breneran ovens

The Breneran or Buleryan stove is a highly efficient small-sized heating device manufactured by Canadian, German and Russian companies. It remotely resembles a classic potbelly stove, but has its own improved characteristics and high efficiency. Furnaces of this type are produced in series, the model range differs in power and design. You can make a Breneran oven with your own hands. The choice of a product depends on the area of ​​the room and its purpose, the space allocated for the oven, the estimate and the necessary functions.

Description of the Breneran stove

The Buleryan stove is a development of the German company Bulerjan, which produces heating equipment. The name Breneran is understood to mean the same devices, but created by Russian companies under license.

Characteristics:

• There is a flat platform at the top. Used to heat food.
• The shape is cubic instead of the usual cylindrical.
• There is an ash pan and a grate.
• Convection heat exchangers are recessed into the body.

Initially, the product was conceived as a stove with an air heat exchanger, but its expediency is not justified. The heat capacity of such a device is low, due to which the efficiency decreases.

Owners use different storage devices for convection pipes to retain heat. 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 summer 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, wood chips, shavings are used as fuel. It is not advisable to choose coal as a raw material in the original furnace, since deformation of the case may occur from high temperatures. This prohibition can be circumvented by upgrading the device. It is necessary to make a collector at the bottom of the heat exchanger and supply air with a blower.

There are two types: the Breneran boiler with a water circuit and the Breneran gas generating furnace. The first type is powered by water heating at home, and the second is powered by gas. Also, gas generating devices are often used for cooking.

Design features and principle of operation

The Breneran stove from Canadian specialists has the design of a long-burning convection boiler. They enlarged the furnace doors, made a different shape of the blower in the form of a branch pipe and put a throttle inside to regulate the air level. To control the power of the furnace, a lever is used that controls the throttle.

The firebox is a metal cylinder with 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 body of the stove, the air receives up to 70% of the heat from the wood. This allows the air to be heated up to 100 ° C at an oven temperature of 60 ° C.

The firebox is divided into three chambers. A grate or metal underneath is installed in the lower part. A metal sheet is mounted under the arch of the firebox. Volatile compounds are burned out in the upper chamber.

Combustion products are discharged through a special opening in the afterburner. At the beginning of the chimney, a damper with a 90 ° sector is made. To select the correct traction, a gap is made around the metal plate that adjusts it. It is equal to 10-15% of the chimney diameter.

The original furnaces also have a device for pyrolysis combustion of gases - an economizer. It is installed near the outlet on the horizontal section of the chimney. In order for the combustion products to have time to cool down, the pipe must have an optimal height.

Advantages and disadvantages

The positive aspects of Breneran include:

• Mobility. The product has a compact size, so it is convenient to transport it.
• Compactness. The configuration of the furnace allows the device to be installed in small temporary buildings.
• Safety. It is achieved due to the tightness of the working chamber and the use of a scheme with one door. There are also barriers to accidental contact with hot metal parts.
  
• High performance. The room is heated as soon as possible due to forced convection.
• Possibility of long-term functioning. The Breneran sauna stove can work for several hours from one load of fuel.
• Ease of operation and high reliability.

The disadvantages include achieving high productivity only when using completely dry firewood. Humidity over 10% reduces combustion intensity and reduces efficiency. Also, the oven does not keep heat well. After the fuel burns out, the room temperature decreases. To improve the efficiency of work, it is also important to make additional thermal insulation of the chimney.

Oven operation and maintenance

In order for the Breneran oven to work efficiently, the operating conditions and proper maintenance of the heater must be observed.

The main advice given by experts:

• You can only heat with dry, finely chopped wood. They put paper or cardboard under them.
• It is not recommended to warm up the oven with the damper 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 the firewood has completely burned out, the stove switches to gasification mode. To do this, shut off the gate and choke.

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 5 meter high pipe.
• The gate valve is closed.
• The smoke channel is clogged with soot. It needs to be cleaned. Preventive cleaning is carried out once a year.

Stove contamination impairs 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 stoves, capable of heating an area of ​​400 sq.m. Made from steel. It can work for 10 hours. Used for heating cottages and country houses.
• Aqua Breneran. Heating is carried out by circulating the liquid and heating it. Suitable for heating large areas, workshops, workshops. Operating time from one fuel tab is 6-8 hours. There is a water tank.
  
• Breneran AOT-08 type 005. Allows you to cook food and heat the house. The gas generator oven is suitable for heating small rooms.
• Aquaten. This is a unique oven 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 heating element with a capacity 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 the power, the type of fuel, the dimensions, the required functions.

If you have the skills and professional equipment, you can create a furnace yourself according to the instructions.Also, a home craftsman can modernize it with his own hands.
