Definitions

  • the invention relates to a boiler for the combustion of liquid or gaseous fuels, consisting of an essentially cylindrical inner housing guiding the heating gases and the heat transfer medium, which is arranged in a heat-insulated manner in an outer housing on which the boiler control housing is located on the operator side.
  • Such boilers are well known and in use, so that no special printed evidence is required in this regard.
  • large boilers which generally correspond to the shape of the water- and gas-carrying inner housing in terms of their insulating outer sheathing
  • box-shaped housings also include a great deal of free space, since a certain amount of heat always builds up in the upper region, despite the thermal insulation of the inner housing, which can have adverse effects on the boiler regulations which are generally placed directly on these housings and on the electronic components located therein.
  • the invention is therefore based on the object of adapting boilers of the type mentioned better with regard to their outer housing to the shape of the inner housing, with the proviso that at the same time to provide a thermally exposed arrangement of the housing for the boiler control and ultimately also for an improved rigidity the relatively large side walls.
  • This design of the outer housing results in improved stability of the side walls despite the use of thin sheet metal, the space between the inner and outer housing is reduced to a minimum and the radiation surface of the inner housing, which is still effective upwards, is correspondingly reduced and also the surface of a cuboid housing, on which the housing for the boiler control sits, which is also better exposed to the air flowing into the outer housing, in contrast to the arrangement on a previously much larger surface of the housing, through which the attached controller housing is inevitably in a flow shadow.
  • the width of the attached housing for the boiler control can correspond to the width of the surface of the housing, but a larger width is preferred in relation to the surface, since the housing for the boiler control thus projects beyond the surface of the outer housing on both sides and thus more strongly the inflowing air is exposed.
  • the boiler is advantageously designed in such a way that the distance from the surface to the center of the inner housing is greater than the distance from the center of the inner housing to the base of the outer housing.
  • an advantageous further development of the boiler consists in that an intermediate wall parallel to the surface is drawn in at least in the arrangement area of the boiler control housing in the upper part of the outer housing. Apart from this, such an intermediate wall, since this necessarily results in a channel, has the advantage that the cables and cable connections leading to the boiler control can be conveniently accommodated in such a channel.
  • the outer casing according to the invention is an ideal solution, since this flue gas discharge pipe is the smallest external space stress can be arranged in the upper part of the outer housing, the side walls, because converging upwards, still offer enough space to still be able to accommodate the exhaust pipe with sufficient thermal insulation. In this case, of course, the insertion of a partition, as mentioned above, is absolutely necessary.
  • the boiler consists of an essentially cylindrical inner housing 1 which guides the heating gases and the heat transfer medium and which is arranged in a heat-insulated manner in an outer housing 2 on which the housing 3 of the boiler control is seated on the operator side.
  • the outer housing 2 is formed from upwardly converging side walls 6 which end in a housing surface 5 which is narrower than the base surface 4, of which partial regions 7 which are adjacent to the cylindrical inner housing 7 form cylindrical partial surfaces 8 which are arranged concentrically with the center M of the inner housing 1.
  • the width B of the surface 5 of the outer housing 2 can either be the same or larger than the width B 1 of the housing 3 of the boiler control placed thereon.
  • the embodiments according to FIGS. 3, 4 are preferred.
  • the housing 3 of the boiler control thermally as exposed as possible in relation to the inner housing and to be able to accommodate the flue gas discharge pipe 11 with the appropriate insulation in the upper part, given the corresponding construction of the inner housing 1 (see FIG. 2)
  • Distance D (see Fig. 3) of the surface 5 to the center M of the inner housing 1 is larger than the distance D 1 of the center M of the inner housing 1 to the base 4 of the housing 2.
  • the embodiment according to FIG. 4 differs from that according to FIG. 3 only in that the side walls 6 are slightly bent in the lower region and abut the base area 4 perpendicularly, which of course also advantageously contributes to the stiffening of the side walls 6.
