Definitions

• the object of the invention is the stand-alone fireplace intended for burning organic material, particularly wood, heating the room in which it is located by means of heating the air.
• the stove substantially consists of the body, base, grate and upper cover.
• the body is a centrifugally cast sleeve, with the same internal diameter, rigidly connected at the bottom with the base.
• the base is the bottom of the ash pit.
• the body has a smoke hole at the upper part.
• the grate is placed inside the body on the vertical supports attached to the base. The grate rests on the vertical supports located in the holes of the body.
• the stove is further provided with protective or decorative elements attached releasably to the body.
• the stand-alone fireplace comprises the combustion chamber being a body mounted on the legs, wherein the body is provided with the door for supplying the fuel into the combustion chamber and the combustion chamber is connected with the after burning chamber placed above the combustion chamber.
• the fireplace is characterized in that the after burning chamber is placed at a distance from the combustion chamber and the two chambers are connected by a connector in which the pipe supplying the air is placed, and the after burning chamber has two sets of pipes placed at the sides of the after burning chamber.
• the after burning chamber has the inlet and the outlet placed on the same side.
• the after burning chamber has a transverse partition.
• the sets of pipes are placed inside the after burning chamber aslant with respect to the vertical and are attached at the lower and upper metal sheet of the after burning chamber, whereas from the top they are covered with the metal sheet with holes.
• the pipe supplying the air has two rows of holes from the top.
• the connector is provided with the insulation, preferably in the form of fire-brick lining. The holes are calibrated.
• the stand-alone fireplace according to the invention allows the use of various types of organic materials for room heating. At the same time the construction of the fireplace allows for more efficient use of heat produced by burning organic material and more efficient use of chemical energy contained in the fuel, that is organic matter.
• fig. 1 shows a longitudinal section of the fireplace
• fig. 2 is a view of the fireplace from its inlet side
• fig. 3 is a cross section through the pipe
• fig.4 is a top view of the pipe
• fig. 5 shows the cross section of the after burning chamber.
• the stand-alone fireplace comprises the combustion chamber 1 being a body mounted on legs 2, wherein the body is lined with a fire brick 3 and is provided with the door for supplying the fuel into the combustion chamber 1.
• the combustion chamber 1 is connected with the after burning chamber 4 placed above the combustion chamber 1.
• the after burning chamber 4 is placed at a distance from the combustion chamber 1 and both chambers 1 and 4 are connected by a connector 5, provided with an insulation in the form of the fire brick, which contains a pipe 6 supplying the air.
• the after burning chamber 4 has two sets of pipes 7 placed at the sides of the after burning chamber 4.
• the after burning chamber 4 has the inlet through the connector 5 and exhaust gas outlet through the flue 8 placed on the same side.
• the after burning chamber 4 has a transverse partition 9, which forces the passage of the exhaust gas twice along the after burning chamber 4.
• the sets of pipes 7 placed inside the after burning chamber 4 aslant with respect to the vertical and attached at the lower and upper metal sheet of the after burning chamber 4 conduct the air which is heated by exhaust gas passing inside the after burning chamber 4.
• the outlets from sets of the pipes 7 are placed in the space covered with the metal sheet 10 with holes which allows placing dishes with food onto it and heating them.
• heat collection from the exhaust gases takes place through the entire metal housing of the after burning chamber 4 and through the sets of pipes 7 housed inside the after burning chamber 4.
• total gas combustion takes place in the after burning chamber 4, since the additional air is supplied through a pipe 6, in particular, through the calibrated holes 11 and by extending the exhaust gas flow path in the after burning chamber 4.
