Definitions

  • the invention relates to a boiler with a boiler housing, with a provided in the boiler housing combustion chamber having a combustion chamber lid with a Rauchgaszustory, the Rauchgaszulinger opposite combustion chamber floor and two adjoining the combustion chamber lid and opposing combustion chamber side walls, which converge towards each other in the direction of the combustion chamber floor v-shaped are arranged and each having at least one side wall brick, in particular firebrick, and having at least one support on the boiler housing having a first and second supports, which each form at least one bearing surface on which bearing surfaces the side wall stones of the combustion chamber side walls (9 and 10) rest.
  • such a trained combustion chamber can not ensure a free thermal expansion of the sidewall stones by heating load, whereby the service life of the combustion chamber and thus the stability of the boiler can be reduced.
  • a complete disassembly of the combustion chamber is required, which in turn significantly increases the maintenance requirements of such a boiler.
  • the invention is therefore based on the object, starting from the above-described prior art, a boiler with a V-shaped combustion chamber constructively to train so that both its stability, as well as its ease of maintenance can be improved.
  • the invention achieves the stated object in that the support has a third support, on which rests the combustion chamber lid, and that the bearing surfaces of the first and second support on which the side wall stones rest loosely, obliquely.
  • the side wall stones can be weight-relieved of the combustion chamber cover and also of the cargo bearing thereon.
  • This can not only bring advantages in terms of the possible formation of the sidewall stones, but also simplify the construction of the support of the combustion chamber.
  • it may thus be possible to facilitate the thermal expansion of the sidewall stones, as they are at least weight-relieved of other parts of the combustion chamber.
  • the durability of the combustion chamber can also be improved. But especially in combination with the feature that the bearing surfaces of the first and second support on which the side wall stones rest loosely, run obliquely, these advantages can be particularly unfold.
  • each other v-shaped tapered combustion chamber side walls can thus not only resistant by the inclined support surfaces, but also be designed to be particularly easy to maintain by the loose resting of the sidewall stones - such as in that case that burned sidewalls are replaced, for example, a combustion chamber door on the boiler.
  • the inventive, constructive change in the support of the combustion chamber can thus lead to a structurally simple and particularly stable - but also to a comparatively easy to maintain - boiler.
  • the support has a fourth and fifth support with oblique bearing surfaces, wherein the sidewalls of the opposite combustion chamber side walls with their lower stone ends on the inclined bearing surface of the first or second support and with their upper stone ends on the oblique Loosely rest support surface of the fourth or fifth support.
  • a support of the sidewall stones provide for a particularly accurate positioning of the sidewall stones, which can contribute to the improvement of stability and function of the combustion chamber.
  • the boiler can be structurally further simplified by the support having at least one first rail with at least one oblique profile leg, which forms the inclined support surface of the first or second support.
  • a first rail to ensure a stable connection of the support with the boiler housing.
  • first profiled rail has two profiled legs running towards each other in a v-shape, which form the bearing surfaces of the first or second support, a bearing point for the converging sidewall bricks can be created in a constructive simple manner.
  • a rail for accurate and easy relative positioning of the sidewall stones contribute to each other, which can ensure, inter alia, a precisely constructed combustion chamber for a reproducible manufacturable boiler.
  • the positioning of the sidewall blocks and thus the design accuracy of the combustion chamber can be further increased if the first rail has a horizontal web on which rest the sidewall blocks of the opposing combustion chamber side walls. Furthermore, this additional horizontal support ensure that any gap at the top of the sidewall stones is safely reduced due to their thermal expansion. In this way, a particularly gas-tight connection of the sidewall stones can be ensured in the combustion chamber and also the efficiency of the boiler can be increased.
  • the support can be structurally simplified if the support has a second and a third rail, each forming an inclined support surface of the fourth or fifth support and each bearing surface of the third support.
  • a precise relative positioning of the sidewall blocks relative to the combustion chamber cover can thus be ensured, which can ensure a high degree of dimensional accuracy at the combustion chamber.
  • the combustion chamber floor can also be formed by the side wall blocks by the side wall stones of the opposing combustion chamber side walls adjoin one another at the apex of their v-shaped course and form the combustion chamber floor there.
  • the design structure of the combustion chamber can be further simplified if the combustion chamber has a combustion chamber rear wall with at least one rear wall brick, in particular firebrick, which adjoins the side wall stones and closes the combustion chamber, and that the combustion chamber has a Saugzugan gleich at the combustion chamber rear wall opposite combustion chamber front side.
  • the maintenance of the boiler can be greatly simplified if the boiler has a lockable with a combustion chamber door access to the combustion chamber, which is designed to replace the sidewall stones.
  • this access can be used to simply remove spent sidewall stones and replace them with new sidewall stones. This can also be particularly easy to handle by the loose storage of sidewalls.
  • the combustion chamber side walls 9, 10 are formed in the direction of the combustion chamber floor 8 each other v-shaped extending, resulting in cross-section below the filling space 3, a v-shaped combustion chamber 5.
  • the combustion chamber 5 is connected via a support 11 to the boiler housing 2.
  • the support 11 has a first support 12 and a second support 13, which respectively form support surfaces 12.1 and 13.1, on which the side wall stones 9.1, 10.1 of the combustion chamber side walls 9, 10 lying opposite each other rest.
  • the bearing surfaces 12.1 and 13.1 of the first and second supports 12, 13 run obliquely - that is inclined to the horizontal and vertical.
  • the support 11 shows a third support 14 with a horizontal support surface 14.1, on which the combustion chamber cover 6 rests.
  • the support 11 has a fourth support 15 and a fifth support 16, each with oblique bearing surfaces 15.1, 16.1.
  • These additional supports 15, 16 each form an upper loose storage for one side wall brick 9.1, 10.1.
  • the side wall stones 9.1, 10.1 can be kept particularly free of stress during thermal expansion and contraction, as can be ensured by the loose resting of the upper stone ends 17, 18 of the side wall stones 9.1, 10.1 on the inclined support surfaces 15.1, 16.1 for sufficient freedom of movement.
  • the lower stone ends 19, 20 of the sidewall stones 9.1, 10.1 loosely rest on the inclined bearing surfaces 12.1, 13.1 of the first and second supports 12, 13, the sidewalls 9.1, 10.1 can be replaced easy to handle, which improves the ease of maintenance of the boiler 1.
  • the support 11 has a first profiled rail 30.1 with two profile legs 21, 22 which tap each other in a V-shape. These oblique profile legs 21, 22 form the oblique bearing surfaces 12.1, 13.1 of the first support 12 and the second support 13.
  • the first profiled rail 30.1 of this type also has a horizontal web 23 on which the two side wall stones 9.1, 10.1 of the opposing combustion chamber side walls 9, 10 and thus on the boiler housing 2 are seated. This facilitates the positioning of the side wall stones 9.1, 10.1.
  • the first rail 30.1 is with Kesselêt 2.1 of the boiler housing 2 firmly connected, as shown for example via a screw 25th
  • the support 11 also has a second rail 30.2 and a third rail 30.3.
  • the second profile rail 30.2 forms both an oblique support surface 15.1 of the fourth support 15 and a horizontal support surface 14.1 of the third support 14.
  • the third rail 30.3 forms both an inclined support surface 16.1 of the fifth support 16 and a support surface 14.1 of the third support 14.
  • the second and third rails 30.2, 30.3 are each mounted on a boiler wall 2.1 of the opposite boiler walls 2.2 of the boiler housing 2, for example, welded to the boiler walls 2.2.
  • the combustion chamber 5 also has a closed combustion chamber rear wall 26 with a V-shaped back wall brick 27 made of chamotte.
  • the rear wall brick 27 adjoins the side wall stones 9.1, 10.1 and there closes the combustion chamber 5 gas-tight.
  • the triangular-shaped Saugzugan gleich 29 is provided - as this in the FIGS. 1 dashed lines is drawn.
  • the Saugzugan gleich 29 is bounded by the opposing combustion chamber side walls 9, 10 and the combustion chamber 8, whereby a particularly advantageous guidance of the flue gas 7.1 through the combustion chamber 5 and subsequently on both sides of the combustion chamber 5 back to the heat exchanger 31 is made possible.
  • the combustion chamber side wall 9 is lined with three side by side provided, cuboid side wall stones 9.1, 9.2, 9.3. Such a lining also exists in the combustion chamber side wall 10, which is not shown.
  • the boiler housing 2 is known to be associated with an enclosure 32 or has it, which enclosure 32 has a heat-insulating function, for example.
  • the access 34 is formed in shape and size for exchanging the side wall stones 9.1, 9.2, 9.3 or 10.1, 10.2, 10.3.
  • spent sidewalls 9.1, 9.2, 9.3 or 10.1, 10.2, 10.3 can simply be pulled out and replaced by new sidewall stones 9.1, 9.2, 9.3 or 10.1, 10.2, 10.3 by inserting them, which is considerably facilitated by the profiled rail-shaped supports 11.
  • the profile rails 30.1, 30.2, 30.2 are preferably aligned with their longitudinal directions on the access 34.
