Definitions
- the invention relates to a boiler for solid fuels, in particular from renewable raw materials, provided with a combustion of solid fuels Brennraurh having a refractory and gas-tight wall lining of several juxtaposed wall stones, especially firebricks, of which at least one wall brick with its laterally adjacent Wall stones forms abutment surfaces, which taper in the direction of the combustion chamber in a wedge shape.
- the invention is therefore based on the object, starting from the above-described prior art to provide a refractory and gas-tight wall lining for a combustion chamber, which is not only a long service life but also comparatively simple and inexpensive.
- the invention achieves the stated object in that the abutment surfaces additionally taper in a wedge shape in a direction other than the direction of the combustion chamber, in particular in the direction of the combustion chamber floor. If the abutment surfaces additionally taper in a direction that is different from the direction of the combustion chamber, the wedge surfaces or abutment surfaces can be made possible by means of the double wedge effect of the wall stone that forms a particularly gas-tight connection. In contrast to the prior art can therefore always be provided without sealant for a gas-tight wall lining, so that a high stability of the wall lining can be ensured. In addition, the design effort can be reduced by the double wedge effect of the wall stone, because even with manufacturing tolerances can be created by the double wedge shape a perfect fit connection between the wall stones. The invention is therefore characterized not only by a good stability, but also by a constructive simplicity and thus cost-effectiveness of the combustion chamber. In particular, a particular double wedge effect may result if the abutment surfaces additionally taper in the direction of the combustion chamber floor.
- the wall lining consists of four wall stones, with two opposite wall stones form the wedge-shaped tapered abutment surfaces.
- At least one wall brick has openings for the air supply.
- an elastic seal is provided at least between the wall stones on the side facing away from the combustion chamber, then not only can the wall stones be firmly seated in the composite, but the wall lining can also be improved compared to a gas passage at the connection points. For this purpose it can be provided that in the region of the connection points between the wall stones on the side facing away from the combustion chamber, an elastic seal is provided.
- 1 is a three-dimensional view of a wall lining a combustion chamber
- Fig. 3 is a three-dimensional view of a wall brick of the wall lining
- Fig. 4 is a sectional view through the combustion chamber of a boiler only partially shown.
- refractory wall lining 1 of Fig. 4 illustrated combustion chamber 2 of a boiler 3 defines a combustion chamber 4 for burning solid fuel 5.
- the wall lining 1 consists of several wall stones 6, 7, 8 and 9, which are arranged side by side so that flue gases of the combustion chamber 2, the wall lining 1 can not penetrate.
- wall stones 6, 7, 8 and 9 and fireclay bricks can be used as wall stones 6, 7, 8 and 9 and fireclay bricks can be used.
- the wall stones 6, 7 and 9 form between them abutting surfaces 10 and 11, the tapered in the direction 12 of the combustion chamber 4, which can be seen in FIG. 2.
- the abutment surfaces 10 and 11 receiving planes 10 ', 11' thus form a directed in the direction 12 of the combustion chamber 4 wedge.
- Two opposite wall stones 8 and 9 of the four wall stones 6, 7, 8 and 9 are of identical shape, and each have wedge-shaped tapered abutting surfaces 10, 11 and 14 and 15 respectively.
- the combustion chamber 4 is supplied via an air supply 16, 17 combustion air 18, which can be better taken from Fig. 4.
- an air duct 21 is provided for this purpose.
- an elastic seal 23 is provided between the wall stones 6, 7, 8 and 9 on the combustion chamber 4 side facing away, which also in the area of the connection points 24 of Wall stones 6, 7, 8 and 9 ensures a tight seal of the combustion chamber 4 with respect to the combustion chamber wall 22.
