Definitions

  • the invention relates to a heat storage furnace according to the preamble of the first claim.
  • the invention has for its object to take measures in a heat storage furnace designed according to the preamble of the first claim, by means of which an exchange of the heating element from the front is made possible with the heat insulation layer remaining largely on the storage core.
  • the part of the heat insulation layer that is adjacent to the end opening of the recess needs to be removable for the replacement of the heating element, or a slot through which the heating element is passed and the deformable material of the heat insulation layer can already suffice which is then compressed again.
  • a heat insulation layer 1 surrounds a storage core 2 made of heat-storing material.
  • the storage core 2 sits on a floor insulating brick 3 and is crossed by an inverted U-shaped discharge air duct 4.
  • In the memory core 2 there is also an essentially vertical recess 5 which is adapted to the shape of a heating element 6 inserted therein.
  • the electrical heating element 6, like the recess 5, is elongated. It is formed and bent in the longitudinal direction by approximately 90, so that there is an essentially perpendicular arrangement in the longitudinal direction.
  • the bottom end opening 7 of the cutout 5 points to the side wall 8, which is at the front during operation and is directed into the space to be heated, of a housing which overlaps the heat insulation layer on the outside.
  • the adapted connection end 9 of the heating element 6 is inserted, which closes the end opening 7.
  • the heat insulating layer arranged on the front side wall 8 of an outer housing is divided at an inclined parting line 10 in such a way that an independently manageable insulating layer part 11 is formed in the region of the end opening 7 or the connecting end 9.
  • This lower insulating layer part 11 can be removed independently of the remaining heat insulating layer 1, so that the storage core 2 can be exposed in the limited area of the end opening 7.
  • the heating element 6 can be pulled out of the recess 5 due to its arcuate design, only the lower section of the storage core 2 being exposed.
  • the insulating part 11 can of course also be limited to the immediate area of the end opening 7 if the heat radiation from the charged storage core 2 should otherwise be too great in the event of a repair.
  • a deformable heat insulation layer for example made of rock wool or Glass wool to slit the heat insulation layer in the area of the end opening 7, so that the slits can be opened in the event of a repair and the heating element 6 can be replaced.
  • the slitting can only be carried out in the event of a repair.
  • the heating element 6 preferably consists of tubular heating elements which are bent essentially in the shape of a hairpin and are additionally bent in the longitudinal direction of their legs by a total of about 90 ° in a crescent shape.
  • the heating element 6 can thus be exchanged from the front without difficulty even when the heat storage furnace is set in a niche, the exposed radiation part of the storage core 2 being able to be reduced to a minimum by the insulating part 11. This is possible because the end opening 7 only has a height that is a fraction of the radiator length.
  • the heating element can also be constructed from individual ceramic members which can be adjusted to a limited extent, on which a heating coil is wound and which form a rod-shaped arrangement which can be bent in the axial direction.
  • the heating element designed in this way can be pushed upwards under axial deflection through the insertion opening.
  • connection end 9 and the end opening 7, which is very small in height, has the essential advantage that heat radiation from the heating element 6 does not reach Thermal insulation layer 1 or up to a plate closing the end opening, but is absorbed inside the storage core 2.
  • the same also applies to the air conducted through the storage core 2.
  • the air duct can be routed separately from the heating element as a separate air path.
