Pellet furnace with water circuit

The modern pellet oven is a heating device in the design of which the latest technologies are implemented, which made it possible to significantly improve its efficiency, while significantly reducing the mass and dimensions.

The principle of work, implemented in the construction of pellet stoves-fireplaces

The products of the above construction refer to long-burning furnaces. They work on pellet pellets with the realization of the principle used in convection ovens, but without the most part of its inherent flaws.

1. The main difference between convection heaters is heating without the use of a liquid coolant. They heat the air in the rooms, which allows you to reduce fuel consumption and time to warm up.
2. The pellet furnace additionally realizes this principle due to the gas generator (combustion chamber in which the gas released during pellet combustion is burnt) is available in its design. This provides additional heat generation.
3. A number of models of this design provides for the arrangement in them of special convection channels (empty cavities or pipes) located along the entire perimeter of the furnace. This technical solution allows us to use the convection law. Taking the cold air from the floor through the available openings, the pellet stoves-fireplaces heat it, after which hot air tends upward, giving the heat to the room.
4. Pellets are fed to the furnace from a special tank (auger feed), where they fall on the burner or retort. The design is implemented automatic ignition, after which the fuel burns slowly.

In order to increase the efficiency, the pellet oven is supplied with additional technical devices (smoke removal systems, forced air supply, metered pellet supply, etc.).

How is the classical oven-fireplace, working on pellets

The design of furnaces, the design of which allows the organization of heating on pellets, has special elements adapted specifically for the fuel. It:

• Bunker, connected to the pellet furnace (the capacity can be changed, thereby regulating the duration of autonomous operation). This option is not available for pellet fireplaces. They use only a built-in tank;
• Auger feeding of pellets. This device provides batch loading of fuel into the firebox chamber. Has an electric drive reducer;
• burner. The pellet oven is equipped with a retort burner, which works continuously. It allows you to bring the autonomy of such a stove-fireplace to significant indicators (a day or more, depending on the capacity of the bunker);
• Fan (one or more, depending on the model). Provides the required amount of fresh air and removes the resulting combustion products;
• Control Panel. The furnaces of this design have an automatic control system, which is pre-programmed from the touch panel.

It is necessary to understand that such furnaces can not work in the absence of electricity.

Features of products with a water circuit

A pellet stove with a water circuit is a hybrid design. A special circuit, moving along which the coolant heats up, is made from several tubes-registers, which are mounted along the walls of the furnace or directly in it.

Other constructional solutions for the arrangement of the water circuit

There are models of stove-fireplaces in which the question is solved differently. In them, the coolant moves inside the walls, which are made double. This option is called a "water jacket".

The third solution, much less effective and practically not applicable in new models, is the installation of a hot water tank in the upper part of the furnace.

The coolant circuit of any design is necessarily combined with the building's heating system, which makes it possible to use a pellet stove-fireplace as a heating device for the whole house. If necessary, it can be used for the domestic hot water system (hot water for technical needs). In this case, you can use any pellets. The price for them can range from 5500 to 7500 rubles per ton.

The fireplace fireplace not only helps to create an atmosphere of comfort and comfort, allowing you to admire the open languages of a living flame, but can also be regarded as the main heating device (in small cottages) or as a source of backup heat in a large private house heated by a water heating system, Having its own boiler of any design.

Advantages of pellet stoves-fireplaces with built-in water circuit

1. Pellets, the price of which is quite acceptable, are the type of fuel produced. This allows you to specify their geometric dimensions at the production stage, which, in turn, made it possible to automate the supply of such fuel to the fireman's fireplace.
2. The use of such materials has made it possible to achieve continuous operation of the furnaces of this design for a very long time, which facilitates their operation.
3. This fuel makes it possible to realize the adjustment of the output power of the heating device taking into account the actual temperature in the building.
4. All pellet stoves-fireplaces have fireboxes of closed type. Therefore, they do not dry the air in the room and demonstrate a higher efficiency.

conclusions

Innovative technologies implemented in the construction of pellet stoves have made it possible to achieve a significant increase in their performance characteristics and capabilities. This explains the constantly growing demand for products of this type.
