Definitions

  • the invention relates to a boiler housing according to the preamble of the main claim.
  • Boiler housings the firing opening of which is closed by a door leaf
  • the door leaf is sealed by a relatively high frame welded to the front wall of the boiler, which presses against an asbestos cord arranged on the door leaf, which is arranged there between the thermal insulation block and a small limiting web.
  • This known embodiment allows the exhaust gases to reach the welded-on frame largely unhindered by the gap between the thermal insulation block and the combustion chamber necessary for the pivoting of the sealing cover, so that condensate can form on the inside of the frame and destroy the frame.
  • a considerable amount of heat is radiated through the frame, which is not insulated from the outside, and the thermal insulation block sitting on the door leaf is exposed to the risk of damage since it is practically free.
  • a boiler door is known with which the sealing and heat insulation are to be improved.
  • the door leaf consists of two interlocking shells which are kept at a distance by means of spacer cams or insulating material, and the boiler-side gap is sealed with one or more sealing cords, which interact with sealing strips on the door frame.
  • the bowls are in the area a door lock firmly connected.
  • this connecting door lock represents a thermal bridge, the desired improvement can only be achieved with an extremely complex two-shell construction.
  • the situation is similar with a boiler door according to DE-U-1 913 481, which is also constructed in a complex manner and in which the surface or sealing webs on the housing simply rest on the opening edge of the front wall of the housing.
  • these known closures they cannot be used without complete redesign if the thermal insulation is designed on the inside as a thermal insulation block, which also partially protrudes into the front wall opening.
  • the invention is accordingly based on the object of designing a boiler housing of the generic type in the front wall area in such a way that the exhaust gases are kept away from the critical sealing area and thereby condensate formation and heat radiation in this area are largely prevented with the proviso that the thermal insulation block is largely protected against damage.
  • another seal is advantageously arranged in the region of the end edge between the thermal insulation block and the sealing web, with which the resulting cross-sectionally conical
  • the gap between the block and the sealing web is shielded, which means that the shape of the sealing web and insulation block can be eliminated.
  • a circumferential step can be easily formed in the thermal insulation block, for example when the thermal insulation block is being formed, which together with the sealing web forms a groove into which the further seal can be inserted, which is made of the same material as the thermal insulation block but is designed as a cord .
  • ceramic fiber material with high temperature resistance can be used as the material.
  • a braided asbestos cord or another suitable sealing material is provided for the other seal that sits on the boiler wall.
  • the front wall of the boiler housing in question has two or more openings, there is of course nothing to prevent a corresponding number of heat insulation blocks and sealing webs from being arranged on a door leaf in accordance with the number of openings arranged in the front wall.
  • the front wall 5 of the boiler housing is provided with a closure which is formed from a door leaf 1 with an inside heat barrier block 2 projecting into a front wall opening 6.
  • a sealing web 3 comprising the flanks 12 of the thermal insulation block 2, the end edge 4 of which is pressed against the seal 7 arranged on the front wall 5 and surrounding the front wall opening 6.
  • the thermal insulation block 2 is largely seated with its entire height within the circular sealing web 3, and in a further development is advantageously sealed with a further seal 8 with respect to the sealing web 3 itself, in order to thereby remove the conical gap between the thermal insulation block 2 and to also seal off sealing web 3.
  • the seal 7, which is essential for the overall seal is no longer seated on the door leaf 1 itself, but rather at a relatively large distance from it, directly on the front wall 5 itself, which expediently has a front wall opening edge 9 and a larger front wall opening web 10, which is entirely in with respect to the overall spatial arrangement can have the width B shown.
  • a circumferential step 11 is formed in the thermal insulation block 2 from the outset, which, as can be seen, forms an annular groove with the sealing web 3, in which the seal 8 is arranged as a further seal.
  • the front wall opening 6 in FIG. 1 is, for example, the combustion chamber opening of the boiler housing. 2, 3 shows a door leaf 1 and a front wall 5 of a boiler housing which has two front wall openings 6, the lower opening being the combustion chamber opening and the upper opening being a cleaning opening.
  • the rectangular door leaf 1 is provided with two corresponding heat insulation blocks 2 and two sealing webs 3 surrounding these insulation blocks, but the same design principle being implemented for each opening closure as described for FIG. 1.
  • the described door leaf construction naturally also has the advantage that the thermal insulation block 2 is largely protected from damage.
