It is also possible to arrange a plurality of rows 2002 of heat storage elements next to each other, and it is also possible to set up several rows 3002 of heat storage elements on these juxtaposed rows 2002.
  • the juxtaposed rows 2002 of heat storage elements are each mounted on a support member 4002 so that they can be held in a stable position; they can also be placed on a common support element.
  • Each support element is in turn mounted on a carrier element 5002 in order to adjust the heat storage device in height, depending on the height of the combustion chamber.
  • This heat storage device can be placed in a heater in the form of a hot water boiler.
  • the heater has a combustion chamber in which the heat storage device is placed.
  • the hot gas stream generated by the burner not shown heats up the wall of the combustion chamber and flows from the combustion chamber into the flues of the hot water boiler before the flue gas is led into the chimney. The heat is transferred to the boiler and thus to the water flowing through it.
  • the arranged in cascade heat storage elements are warmed up by the hot fuel gas stream and, during the turn-off of the burner can deliver their heat to the wall of the combustion chamber and thus also to the water in the boiler.
  • the heat storage elements are, as shown, with a corner directed downwards, depending on the position on the support element or on the juxtaposed rows;
  • the above-mounted in the hole wall gap is preferably in a corner of the hexagonal shape, but may also be located in a flat side of the hexagonal shape.
  • the heat storage elements may also be positioned with a flat side downwards, in which case the gap provided on the top in the hole wall is preferably, but not necessarily, also in a flat side of the hexagonal shape.
  • the upper heat storage elements are placed either directly or via a separate support element on the lower heat storage elements.
  • the heat storage element preferably has a hexagonal shape, as shown, but may also be polygonal or even round or oval.
  • the through-hole is preferably arranged round and centric, as shown, but may also be arranged eccentrically and / or have an oval or polygonal shape.
  • the smallest diameter of the through-hole may be at the beginning, at the end or in between. It has been found that good results are achieved when the through-hole tapers inwardly from both sides, with the smallest diameter of the through-hole being preferably approximately in the middle third.
  • the smallest diameter of the through-hole may extend over a small distance, parallel to the direction of the through-hole, which may be advantageous for manufacturing reasons.
  • the figures show (see especially Figures 12 and 14) that the above-mounted in the hole wall gap is located in a corner of the hexagonal shape. Alternatively, the gap may also be between two corners. These figures also show that, in the juxtaposed heat storage elements, the gap mounted on the top side in the hole wall is directed outwards.
  • the figures also show (see in particular Figures 12 and 14) that the juxtaposed rows of heat storage elements are each per row placed on a support element.
  • these rows of heat storage elements can also be set up on a common support element.
  • the carrier element 5002 can also be designed to be multilayered for this purpose, for example consisting of an upper layer which is even more thermally conductive than a layer of ceramic material underneath, in order to reduce heat transfer to the ground. LIST OF REFERENCE NUMBERS

Abstract

L'invention concerne un procédé et un dispositif de commande pour faire fonctionner une installation de chauffage. L'installation de chauffage comprend une chaudière comportant une chambre de combustion dans laquelle est placé au moins un élément accumulateur de chaleur. L'installation de chauffage contient en outre un brûleur pour chauffer la chambre de combustion, un corps de chauffe et une sonde de température, une pompe et un circuit d'eau passant par la chaudière, la pompe et le corps de chauffe puis retournant à la chaudière. Le procédé selon l'invention comprend les étapes suivantes : lorsque le brûleur et la pompe sont en marche, contrôler si la température mesurée par la sonde de température dépasse une première valeur seuil; si la température mesurée dépasse la première valeur seuil, arrêter le brûleur et laisser fonctionner la pompe; lorsque la pompe a continué à fonctionner, arrêter la pompe. L'invention concerne en outre des systèmes d'accumulation de chaleur dans des installations de chauffage de plus grande taille.
