Definitions

  • the invention relates to a boiler storage combination, consisting of a lower, water-bearing housing containing the furnace, on which a likewise water-conducting, housing containing the vertically oriented storage container is arranged and the storage container is provided with hot water drainage and cold water inflow pipes, the water-carrying interiors of the two Connect the housing to each other through an overflow nozzle.
  • the introduction of the cold water supply line from below to the storage tank is also known, which on the one hand has the advantage that the cold water supply line can be used for emptying the storage tank in case of need cleaning, but on the other hand such a lower approach of the cold water supply line to the Storage tank connected with the disadvantage that the cold water supply line that is introduced and extends through the interior of the water-carrying housing is fully from the lower one Housing part is exposed to hot water flowing up, which can lead to rapid calcification.
  • Another disadvantage of such boiler / storage combinations is that the circulation of the heat transfer medium in both housings leaves something to be desired due to the cross-sectional connection.
  • the two housing parts are liquid-tight but separable, which is usually always desirable, this is associated with considerable manufacturing and construction costs, since the two housing parts fit together well and relatively large connection flanges must be provided. If you want to improve the circulation conditions within the two housing interiors, this requires the arrangement of specially arranged and trained baffles in a relatively complex manner, which further increases the manufacturing and construction costs.
  • the invention is therefore based on the object to improve a boiler storage combination of the generic type in such a way that the two parts of the combination can be connected to one another in a simple manner, but with the proviso that at the same time for an improved circulation of the heat transfer medium in the overall boiler and to ensure that the cold water inflow pipe from below to the storage tank is not loaded with rising hot water.
  • the hot water rising from the hottest, burner-side area of the furnace is directed into the gap between the housing wall and the storage tank on the same side, which then rises in this gap area and heats up the storage tank there, while the correspondingly cooled heat transfer medium for the storage tank, since there is no other way available, flows back to the rear overflow nozzle on the other side in order to get back into the lower housing through it.
  • a temperature difference of the heat transfer medium, measured at the front and rear overflow connection of approximately 10 ° C. can be measured.
  • the flow channel provided in the design of the combination in the lower housing according to the invention advantageously also ensures that the heat transfer medium flowing out and cooled from the upper housing does not directly hit the wall of the combustion part, but can flow shielded to the side and flow to the side of the furnace lower housing again in the lower area of the firing part.
  • the cold water supply line can also be easily led from below to the upper housing, this line practically not coming into contact with rising hot water from the lower housing.
  • an advantageous development applicable to both solutions consists in the fact that an annular collar which penetrates the bottom of the upper housing in a liquid-tight manner is arranged in the middle of the bottom of the storage container and the cold water supply line is connected to the bottom of the storage container within this collar. In this case, the cold water supply line advantageously does not come into contact with the heat transfer medium at all.
  • a curved bottom is also provided for this container bottom, which, however, is then provided with flat features for the problem-free connection of the two overflow nozzles, the a characteristic advantageous with respect to the interior of the housing inwards and which is designed for the other nozzle outwards.
  • the two overflow nozzles are provided at their free ends with connecting flanges and connected to flange seat embossments on the wall of the lower housing, i.e. the overflow nozzles are directly in the area of the above-mentioned flat surfaces at the bottom of the connected upper housing, which has corresponding punched openings in the connection area.
  • the flange seat embossments are provided with welded-on stud bolts, with the help of which the respective connection flange can be tightened with the interposition of a flange seal.
  • the combination is advantageously designed in such a way that the foremost wall region of the inflow nozzle in relation to the burner side of the housing is arranged as close as possible to the wall region of this housing adjoining the bottom of the upper housing.
  • the cross section of the front overflow nozzle can advantageously be designed in the form of an elongated hole corresponding to the curvature of the inflow gap in the upper housing.
  • the heating water is no longer circulated by gravity, but by a charging pump in such a way that a line with a charging pump attaches to the top of the heating jacket of the hot water tank.
  • the boiler can be operated as a regulated storage tank as normal, ie if the intended hot water temperature has been set in the hot water storage tank, the pump switches off. By taking hot water and if the If the storage tank is to be heated again, the pump switches on again.
  • hot water can flow from the boiler into the heating jacket of the tank and reheat the tank.
  • the design according to the invention also has the advantage that the hot water from the boiler heats up the lower area of the store, thereby ensuring that no cold zones can arise in the hot water tank and germs introduced with the cold water, e.g. Legionella can also be killed in the lower area of the hot water tank.
  • the boiler storage combination consists of a lower, water-bearing, which contain the furnace 19 the housing 1, on which the likewise water-bearing housing 2, which contains the vertically oriented storage container 4, is arranged and the storage container 4 is provided with a hot water drain line and a cold water inflow line 11.
  • the water-carrying interiors of the two housings 1, 2 are connected to one another.
  • between the two housings 1, 2 are a front, arranged above the burner side 1 'of the lower housing 1 and directed to the gap 3 between the storage tank 4 and its housing 2 overflow nozzle 5 and a rear, on the rear bottom half 6 'of the storage tank 4 directed overflow 7 provided.
  • a flow guide channel 9 which shields the mouth 8 of the rear overflow nozzle 7 and has openings 10 on both sides, from which, as indicated in FIG 17 can flow.
  • the almost ideal circulation flow resulting from this arrangement is illustrated by arrows 20 in FIG. 1.
  • the space between the two housings 1, 2 is used for the approach of the cold water inflow line 11, which is connected in a correspondingly curved manner directly from below to the housing 2 or the storage tank 4.
  • a collar 14, which extends through the bottom 12 of the housing 2 in a liquid-tight manner, is advantageously provided in the center of the bottom 6 of the storage container 4, the cold water supply line 11 being connected directly to the bottom 6 of the storage container 4 within this collar 14.
  • the collar 14 also fulfills a stiffening function for the bottom 12 of the housing.
  • flat shapes 8, 8 ' which also provide additional stiffening of the bottom and represent flat connection areas for the two nozzles 5, 7.
  • the expression 8 is designed inwards with respect to the interior of the housing 2 and that for the socket 7 is shaped outwards.
  • the two overflow ports 5, 7 are provided at their free ends with connecting flanges 15 and connected to flange seat embossments 16 of the wall 17 of the housing 1.
  • the flanges and the flange seat embossings 16 could also be provided in reverse, i.e. the bottom 12 would then be provided with flange seat embossments and the two sockets 5, 7 would be welded directly to the wall 17 in the area of corresponding openings.
  • the wall 17 could easily be provided with flat connection embossments in order not to have to punch out the sheet metal blanks for the formation of the two connecting pieces 5, 7 on one side with a corresponding curve.
  • the flange seat formations 16 could also be in the form of welded and appropriately embossed rings, as shown, directly on the housing wall.
  • the front overflow connection 5 can be designed in the sense of FIG. 3, namely in such a way that the cross section of the front overflow connection is designed in the form of an elongated hole corresponding to the curvature of the gap 3. This results in an even better flow of the heat transfer medium, oriented to the shape of the gap 3.
  • FIGS. 4, 5 relate to the same circulation and arrangement principle, but differ from the one described above in that there is a forced circulation through the connecting line 22 provided with the charging pump 21.
  • the connection line 22 running outside is expediently and advantageously connected to an emptying nozzle 23 going out at the lowest point of the housing.
  • the upper housing 2 lacks a supporting leg
  • the rear wall 24 of the lower housing 1 is provided with an extension 25 which supports the upper housing 2 and which is connected in a suitable manner to the bottom 12 of the upper housing 2.
  • FIG. 5 differs from that according to FIG. 4 in that the connecting line 22 in the interior of the housing 2, as shown. is guided downwards and is connected to the lower housing 1.
  • the line 22 is expediently divided at a suitable point and flanged at this point or connected to a connecting fitting 26 such as the inflow nozzle 5 in FIG. 4.
