Definitions

  • the invention relates to a heating boiler according to the preamble of patent claim 1.
  • a boiler of the type mentioned is from the document DE 197 53 065 B4 known.
  • This boiler consists of a flowed through by a heating medium boiler room, which has a return connection for supplying the heating medium to the boiler room and both a flow connection and an additional flow connection for discharging the heating medium from the boiler room, the return connection arranged in a boiler room and an opening to the boiler room formed flow guidance, wherein the flow guide in the flow connection ausmündend formed and means for adjusting a selectively flowing through the flow connection and / or via the opening through the additional flow connection flow quantity is provided to Schunikmedium.
  • the invention has for its object to improve a boiler of the type mentioned.
  • an effective and cost-effective design for controlling the (total) flow temperature is to be created independently of the boiler temperature.
  • the flow connection and the additional flow connection are designed to open into a common main flow connection.
  • the boiler according to the invention thus characterized by the fact that it is possible with the help of this special flow guide construction in a simple manner, the thermocouple from the provided with a Walkernikpumpe heating circuit at the return connection, relatively cool heating medium practically unaffected by the boiler room lead to the flow connection , Since hotter, directly from the boiler room next heating circuit medium is still available on the additional flow connection, the temperature of the heating medium can be controlled at a common outlet or at a central main flow connection of the boiler, by selectively setting the ratio of the coming from the flow connection and from the additional flow connection Kirkreiemediums on the one hand, the flow connection and on the other hand the additional flow connection open, be set exactly. The stronger the flow connection is closed, the more heating medium is introduced through the above-mentioned opening in the boiler room and the hotter the heating medium will then be at the above-mentioned common outlet.
  • an opening is provided on the flow guide means that at least one opening is provided.
  • at least one opening is provided.
  • the boiler according to the invention which - is not shown - preferably as a biomass boiler, in particular pellet boiler, or as a condensing boiler is formed, first in a known manner from one of a Schuffymedmedium (especially water) flowed through the boiler room 1, the one Return connection 2 for supplying the heating medium to the boiler room 1 and both a feed connection 3 and an additional flow connection 4 for discharging the Schunikmediums from the boiler room 1, wherein the return port 2 is formed opening into a arranged in the boiler room 1 and an opening 5.1 to the boiler room 1 having flow guide 5.
  • a Banksianmedium especially water
  • a combustion chamber 8 is formed at least partially enclosing.
  • the combustion chamber 8 is completely enclosed by the boiler room 1, wherein the boiler room 1 has at least one outer wall 1.1 bounding a fluid-tight volume.
  • the flow guide 5 in the flow connection 3 ausmündend formed (ie - apart from the opening 5.1 - fluid-tightly connected) and a device 6 for setting a selectively flowing through the flow connection 3 and / or via the opening 5.1 through the additional flow connection 4 Supply quantity is provided to Schunikmedium.
  • the flow guide 5 not only one, but a plurality of openings 5.1 (for example in the form of round holes), so that coming from the return port 2 Schunikmedium can flow as evenly as possible in the boiler room 1.
  • the openings 5.1 are particularly preferably all formed on the same side of the flow guide 5.
  • the opening is 5.1 or 5.1 in the direction of the outer wall 1.1 of the boiler room 1, at the preferably also the flow connection 3 and the additional flow connection 3 are arranged, arranged pointing.
  • the flow guide 5 is tubular, this measure in relation to the solution according to the invention, for example, channel-shaped flow guides such as shafts, boundaries by separating plates or the like, so in the broadest sense, such guides that are suitable, the Schunikmedium (apart from outflowing Banknikmedium at or the above-mentioned openings 5.1) isolated from the heating medium in the boiler room 1 to lead.
  • channel-shaped flow guides such as shafts, boundaries by separating plates or the like
  • the flow guide 5 is optionally arranged adjacently and predominantly along an outer wall 1.1 of the boiler chamber 1 and / or between the outer wall 1.1 and the combustion chamber 8.
  • the flow guide 5 is integrally formed between the return port 2 and the flow port 3, ie heating circuit medium 5, the flow guide 5 only through the opening 5.1 or 5.1 or via the supply port 3 leave.
  • Essential for the boiler according to the invention is now that the flow connection 3 and the additional flow connection 4 are formed ausmündend in a common, here outside the boiler room 1 arranged main flow connection 7.
  • the flow connection 3 and the additional flow connection 4 are arranged at the same height on the boiler room 1.
  • the main flow connection 7 is formed within the boiler room 1 connected to the flow connection 3 and the additional flow connection 4, ie these two terminals 3, 4, preferably in addition, but also the means 6 for setting the respective Amount of Schunikmedium, are then completely positioned within the boiler room 1.
  • hot Schuttingmedium is thus mixed via the additional flow connection 4 according to the setting of the device 6 at the main flow connection 7, wherein the heating medium is fed through the opening 5.1 and 5.1 openings in the boiler room 1 and heated there.
  • the openings 5.1 are arranged at a distance from the additional flow connection 4 in order to avoid a hydraulic short circuit.
  • the device 6 or the valve is fully opened, there is - if the flow resistance of the flow guide 5 between the return port 2 and the flow port 3 is sufficiently low - for the heating medium no cause or need more about the openings 5.1 in the boiler room. 1 to stream. Rather, it can flow virtually unhindered from the return port 2 via the flow guide 5 to the flow connection 3 and from there to the main flow connection 7 connected to a heating circuit with a heating circuit pump (not shown separately because it is generally known). Since the Schunikmedium is shielded from the flow guide 5 with respect to the boiler room 1, it is, if anything, only slightly heated, ie the temperature of the Schunikmediums at the main flow connection 7 corresponds approximately to the temperature of the heating medium at the return port. 2
