ABOUT COMPANY PRODUCTS APPLICATION SUPPORT CONTACTS Home > For fireplaces FOR FIREPLACES The fireplace can be considered a type of stove with a simplified design. The main difference between the two is the way heat is released. The stove uses the heat of combustion more efficiently, because it has a closed firebox and a massive structure with a developed convective system. In addition, the thick walls of the oven keep heat for a long time. The fireplace has a large furnace hole and a straight flue duct without chimneys (hot flue gases go directly into the chimney), besides, the fireplace masonry is less massive. Hover over an item for information. Unlike a stove, an open fireplace quickly heats up the air in a room, but stops heating as soon as the wood goes out, since the fireplace does not accumulate heat like the walls of the stove. But thanks to this, the fireplace ventilates the room well and prevents the formation of dampness. The chimney is an integral part of every fireplace. According to the fire safety requirements of fireplace chimney systems, it is necessary to use an insulated chimney - a sandwich with an inner pipe, a layer of thermal insulation, and an external circuit. At operating temperatures of the fireplace exceeding 500 ° C, manufacturers are obliged to take into account the phenomenon of loss of mass of binder fibers due to their evaporation, which is called thermal destruction of phenol-formaldehyde binder insulation. The activity of this process increases rapidly when the temperature exceeds 250 ° C. To ensure the guaranteed operational life of the fireplace chimney system, its insulation must have a density of at least 120 kg / cubic meter, and the thickness of the heat-insulating layer must be at least 40-50 mm.
