Fireplaces great variety of systems, but this article deals with one of the most simple fireplace – brick, which the owners themselves can add up in suburban or garden house. What are the requirements to the fire? – Fireplace not should smoke – fireplace must have a good warm up the air – fireplace must be beautiful and fit into the interior. Dimensions Dimensions of the furnace combustion of sizing fireplace with his hands begin with the definition area and volume of the room where the fireplace will be arranged. For example, a porch or a room country house with area of 10, 15 or 20 meters, ceiling height 3.3-3.5 meters. Volume of the room will be respectively 35, 50 or 70 cubic meters. m. The area of the flue fireplace openings for these volumes relates to the area of the premises as 1:50 – 1:70 and will be respectively 0.2, 0.3, 0.4 square meters.

m. We define the height and width of the fireplace flue openings, so-called portal firebox. There also exists dependence – for the small fireplace that will be 2:3 (height to width). – Podorbnee here. That is, for our fireplace the size of the portal will be respectively: – 0.2 square meters. m – 36h45 cm – 0.3 sq. km.

m – 44h67 cm – 0.4 sq. km. m – 52h77 cm depth of the firebox fireplace with a tall portal must be in respect of 1:2-2:3, this size is also necessary to observe, as most of the depth reduces the heat in the room, and the smaller is smoke. In our case, this depth will be: – for section 0.2 square meters. m: 18 – 24 cm – for section 0.3 square meters. m: 22 – 30 cm – 0.4 kV for the cross section. m: 26 – 35 cm Now, we have defined the dimensions of the firebox of the fireplace (see Fig. 1). Fireplace smoke hole depends on the size of the firebox opening and must be 8-15 times lower, respectively, it is: 0.02, 0.03 and 0.04 sq. km. m. If the chimney brick chimney, these dimensions are 14X14 and 14X27 correspondingly see if the chimney flue chimney with a circular, its diameter ranges from 8 to 14 cm in height define the chimney, in our case it should be 4-5 meters. The device inserts Fig. 2 The device unit firing furnace for better heat reflecting ability of the fireplace firebox preferably internal walls meet at an angle to the side outward, and back tilted forward, starting with 1 / 3 of the height above the firebox fireplace smoke chamber is arranged between them produced a cornice, which is called a 'pass'. Pass prevents the removal of soot and sparks from the fire outside and smoke inside premises. His device is shown in poryadovkah. So, we figured out basic technical parameters of the fire, will now determine its overall size. We arranged to meet our fireplace brick, hence, all sizes should be given to the unit masonry. Brick has a size of 6,5 X12X25 cm, and masonry seam about 0.5 cm
