Open fireplaces.

Fireplaces - are very different in style era, size, or location. Open fireplace, a simple stoves with open fires in a niche.

Open fireplaces warm up the space of radiant heat. Efficiency of 10-20%, the rest of the heat goes up the chimney. Open fireplaces in the cooler areas can not serve as a heating device, the master of them are rather due to the magic of fire and burning as a decorative embellishment.

Fireplace with open fires is ideal for an evening hanging out, looking at the fire without the glass is to look at the magical flames, which fascinate and soothe. Some doctors argue that it is beautifully shot, everyday stress, fatigue and the treatment of mild neurosis.

The firebox of fireplaces make a square shape, depending on the cubic content of the heated room the size of the furnace is calculated and the diameter of the pipe. Sidewalls fireplace inserts do with the extension to the side of the room. This design allows the fire to reflect more heat into the room.

Fireplaces pose separately from the wall or in a capital brick wall. The thickness of the walls of the capital not less than two bricks.

Fireplaces with open fires, using air for combustion chamber of the room where the fireplace is located, it promotes good ventilation of the room. Installation of the open fireplace is simple, if you have some skills in the construction of it, perhaps, to build their own hands. Fireplace because of good ventilation is often just put in a smoking room rooms rooms.

One of the disadvantages of the open fireplace is, fireplaces produce heat only during the furnace, and uneven. The air is heated against the firebox and the sides facing toward him.

Device fireplace

Open fireplace consists of a firebox and smoke collector. Smoke collection has some difficulty with a tooth or a spark arrester, for example if you take a lighter and light, and the fire to make the plate, we can observe the direction of the flame lighters, if a plate to put under 45 degrees, the flame will be attracted to the plate. Roughly the same role as the tooth is in a fireplace that does not allow the flame to go out into the room, the fire becomes unforeseen direction. Tooth in the collection of smoke plays another role, a return of cold air in the chimney back into the tube, in our time some fireplace inserts in the upper part of the tooth to install another combustion chamber for afterburning sending fire in this chamber the fresh air, which further inflames unburned gases in the furnace of fire. Chamber of the tooth called the secondary combustion chamber, improving combustion of firewood and significantly increasing the efficiency of the fireplace hearth. A striking example of the use of a secondary combustion chamber are fireplace inserts a new series of firm BEF XOME (Czech Republic). Fireplace inserts BEF HOM reach maximum efficiency of 85%.

The device is a chimney in the open fireplace differs increased diameter pipes, in comparison with closed fireplace inserts.

Gas threshold of the fire is smooth and shaped tray. Often, it set the tray, but against him clean, hermetically closed doors.

Pull flue gases in the open fireplace is weak, so at some fireplaces organize large caps or mine, in which the smoke is going to and from the mine will eventually go up in smoke.



Chimney at idle is always open fireplace damper must be closed, or turning a latch. Closed valve prevents fire from the rapid cooling and falling of rain in the fireplace hearth.

The inner walls of the combustion chamber fireplace makes possible smooth. In the back of the firebox usually put a cast-iron stove, which improves heat transfer from the fireplace.

The size and shape of the fireplace may be different, mainly determines the size of a master fire, and customers determine what to decorate it.

For masonry fireplaces use of refractory bricks are put into the combustion chamber and smoke collector base fire can be put on Brick, M 100. Lining fireplace inserts can be a special refractory bricks glazed, which improves durability and beauty of the fireplace hearth.



Heavy fireplaces are placed on a special foundation, lighter on the slab, there are fireplaces lightweight who simply weigh on the beams overlap.

Masonry chimney is made with special care, where the seams should be minimized and the bricks necessarily tied together.

Finish open fireplace

Outdoor fireplaces can be finished a wide variety of materials, the main principle of a finishing material shall conform to temperature loads and expansion in the field of application. Best finish fireplace tiles This material is resistant to heat stress, heat accumulates, and holds one of their best. Beauty in tile overflow and icing the game, and if it is painted with a variety of motives, it's a special color in the house. Tile has a beneficial to human health by ultraviolet radiant heat, which he highlights long after its accumulation. Perhaps fireplaces marble, sandstone or stone, plastered surface also looks good.

On chimneys to put a weather vane is not recommended, as the winter snow falls, it melts, freezes, and stops wind vane, the wind changes direction and all the smoke goes into the room, if it occurs at night, you can get poisoned by carbon monoxide, and not wake up. Weathervanes are prohibited for fire safety. To strive for improved traction in the chimney and putting yourself in danger, you probably should not. Thrust into the chimney should be sufficient in extreme cases, may establish a stationary engine is forced to improve traction in the pipe. Location of the fire may have walls in the corner or middle of the room. Better when the fireplace is located facing the entrance to the premises when the device of any fire obey all fire prevention measures. Before you install the fireplace firebox sheet steel, it protects against accidental sparks.

When masonry fireplaces made of brick or stone firebox cover ovenproof beam. Possibly overlapping spread the arch of the fireclay bricks. To do this, make special templates arch, and they lay out the arch. Use of steel beams is not recommended, since it has different thermal expansion that eventually destroys the chimney masonry, and leads him to fail. Also use the jumper from the heat-resistant concrete, it is less prone to deformation due to thermal loads.

In fireplaces with open fires for better use of woodfuel use grate on the legs (Taganka), who just put in a niche of the fire, thereby improving the burning-wood. Spread in a recess firebox ash chamber is not recommended, thus you change air flow into the fireplace, and violated directed fire burning. The flames from time to time to throw in different directions, to prove it. Just spend a little experience, erecting two matchboxes two niches with the tooth top. In one niche to make a hole, bottom simulating the ash dump, take a dry alcohol to light it and you will see clearly the difference in the flame. In the first firebox ash without the fire is lit directly enveloping the walls, the second fire would rush to behave unpredictably.
