Recently, heating units, which are called stove-fireplaces or fireplaces, have gained particular popularity. These structures are something between the long-burning furnace and the fireplace with a closed firebox. Furnaces-fireplaces of long burning not only fulfill their basic function of heating the room, but also are a perfect addition to the design of any interior. They deserve the love of the owners of houses due to their advantages:
- high heat transfer;
- the possibility of controlling the combustion process;
- convenience and safety of operation;
- economy due to the burning mode of combustion;
- less need for air when burning in a closed condition;
- universality (possibility of using in the open form);
- The possibility of removing heated air to other rooms.
Heating stoves-fireplaces: the principle of action
The furnace chamber for fireplaces is made of cast iron and is equipped with a tight-fitting door made of heat-resistant glass. Due to the properties of cast iron, such as high thermal conductivity and heat capacity, the air in the room very quickly heats up, and the heat persists long enough. The efficiency of such units can reach 83%. This is achieved through convective heat flows and radiant directed energy. Smoldering combustion mode not only reduces the consumption of firewood, but also ensures maximum heat transfer of raw materials. Therefore, the capacity of the fireplace-furnace can reach 15 kW (if compared with a brick oven, then the power does not exceed 4 kW). But it should be borne in mind that the furnace can not be switched to the continuous combustion mode at once. Because with this mode the temperature in the room does not increase, but only is maintained at a given level. The tightness of the construction allows the unit to produce heat up to 14 hours from a single tab, which in terms of duration of action is not inferior to gas-generating furnaces. For one furnace you can warm several rooms or even a small house. However, the stove-burning stoves in the glowing mode at the outlet from the furnace to the chimney have a low gas temperature of 200-250 ° C. This leads to a more active condensate formation in the chimney.
The furnace can be additionally equipped with a system for cleaning the glass with a hot air jet. The required assembly of the structure is a slide gate, which covers the chimney. When closing the slide gate and the power regulator, the furnace starts to work in a glowing mode due to the intake of air into the furnace in the minimum amount. Modern wood-burning fireplaces provide for the automatic opening of the slide gate during the opening of the door. This excludes the possibility of poisoning with carbon monoxide and combustion products. A distinctive feature of the fireplaces, which adds to their similarity to fireplaces , is the presence in the design of a large panoramic door. Through it a good view of the furnace opens and you can enjoy the sight of living fire.
Furnaces stylized under the fireplace, in the modern market are presented in a variety of forms. You can find models not only of classical rectangular shape, but also gracefully curved and even in the form of streamlined cylinders. Facing fireplaces-stoves by technology and materials does not differ from the finishing of traditional designs of a stove or fireplace. Materials can be a natural stone or mineral, granite or tiles for cladding. The external furnish of the stove-fireplace for the house will turn the hearth into a real work of art and will allow you to fully enjoy the warmth and comfort.
