Definitions

  • the invention relates to a heat generator for hot water preparation and heating operation, consisting of an essentially cylindrical, vertical container with cold and hot water connections, with an upper heating flow and a lower heating return connection and with a burner heater, formed from a burner-equipped, the container penetrating centrally Heat transfer and heating gas routing.
  • Heat generators of this type are known, for example, according to DE-U-91 16 438 and DE-A-39 06 715.
  • heat generators of this type if they are not provided with an electrical heating device, are usually equipped with coils which are connected to the supply and return connections of a boiler and are placed near the boiler or are directly combined with it.
  • the tendency is on the one hand towards boilers with low output, on the other hand, one is becoming more and more demanding in terms of hot water preparation or provision of hot service water, i.e.
  • this hot water boiler should not take into account the tendency mentioned, but rather the calcification of process water flow coils should be prevented, which is to be achieved simply by passing the heating water through a pipe coil, as mentioned.
  • the invention is therefore based on the object, also taking into account the above-mentioned opposite tendency to create a compact and as small as possible structurally simple heat generator that can primarily perform the function of hot water preparation and maintenance, but on the other hand and therefore secondary can also take over the function of a boiler, which should be achievable with simple means by appropriate conversion of conventional heat generators, combined with the proviso that the heating gas duct should be provided with the largest possible heat transfer area.
  • a small boiler (output size, for example, in the range of approx. 12 to 20 KW) is integrated in the form of a simple heating gas flow in an otherwise usual container with, for example, only 100 to 160 liters of content for hot water preparation, the volume of which is significantly larger than the space occupied by the heating gas routing, but the heating gas routing and thus the effective area for heat transfer is significantly increased by using a pipe register.
  • the element for returning the flow in the case of high demand for hot water is significantly simplified and there is no longer a relatively high resistance annular gap for the passage of the heating gases, since these have the total cross section the individual tubes of the tube register are available.
  • the production of the heating gas guides and their installation in the container is very simple, since they can be integrated into the container just as easily as prefabricated units, which will be explained in more detail.
  • the heat generator for hot water preparation and heating operation basically consists of an essentially cylindrical, vertical container 1 with cold and hot water connections 2, 3, with an upper heating flow and a lower heating return connection 4, 5 and with a burner heater 6, formed from a burner , the container 1 centrally penetrating heat transfer and heating gas 7, 8th
  • a pipe register R comprising a plurality of vertically extending individual pipes 13 is arranged as the second part of the heating gas guide 8.
  • the lintel burner chamber 10 is placed on the upper end of the pipe 12 (see FIG. 2) or occupies an upper part of the length of the tube 12 (see Fig. 1).
  • the pipe 12 comprising pipe coil 14 and this is connected at its lower end to the pipe 12, and finally under the closure 11 of the pipe 12 is an exhaust gas collection chamber 15th arranged with exhaust port 16 and condensate drain port 17.
  • the lint burner heating device part 6 'attached to the upper end of the tube 12 is in the form of a double-walled, substantially hemispherical combustion chamber 10' which is connected to the interior of the tube 12.
  • the combustion chamber is arranged outside the water supply, nothing is lost in the heat transfer surface, since the combustion chamber itself is water-conducting and, since it is directly connected to the heat transfer duct 7 in the container 1, forms its upper, most effective end free of process water, which is of particular interest for pure heating operation.
  • the tube 12 is advantageously provided with a frustoconical extension 20 toward the combustion chamber 10 ′.
  • a cylindrical combustion chamber 10 ′′ with a cylindrical surface burner 21 inserted therein is arranged.
  • This embodiment is particularly suitable for larger containers 1, since with such containers there is enough space available to accommodate a correspondingly large combustion chamber and a correspondingly large pipe register R.
  • the connecting line 23 from the flow connection 6 to the line coil 14 could also be arranged running in the container 1 are more advantageous, this connecting line 23 is provided outside the container, especially since this line is equipped with a pump 22 which runs when there is a high demand for hot water.
  • connection 24 of the line coil 14 to the connecting line 23 is arranged laterally on the bottom 1 'of the container 1 (see Fig. 1).
  • the lower end of the tube 12 passes through the bottom 1 'of the container 1, and the return connection 5 is arranged at this projecting end (FIG. 2).
  • the return connection 5 passes through the exhaust gas collection chamber 15 and is arranged on the closure 11 of the tube 12.
