Definitions

  • the invention relates to a heating boiler having a combustion chamber and an exhaust gas collecting chamber communicating with the combustion chamber via exhaust trains entering therein, the exhaust gas collecting chamber having an exhaust gas outlet for connection to an exhaust gas system and having a cleaning opening separate from the exhaust gas outlet, which is closed by a cover device, wherein the lid device is, if necessary, convertible into an open state to enable cleaning access or maintenance access to the exhaust gas collecting chamber.
  • Boilers of the type mentioned above are common.
  • boiler which have muffler devices in the exhaust gas discharges.
  • z. B. on the DE 103 13 339 A1 which discloses a boiler with a muffler device in the exhaust gas collection chamber.
  • the muffler device fills most of the exhaust gas collecting chamber provided on the rear of the boiler and extends far into the exhaust gas outlet.
  • the exhaust outlet with the muffler inserted therein is provided on a large housing cover at the rear of the boiler.
  • a separate cleaning opening for the exhaust gas collecting chamber is in the subject DE 103 13 339 A1 not provided. If there is any need for cleaning or maintenance in the exhaust manifold chamber area, then the complete rear housing cover of the boiler should be dismantled. This should in most cases be associated with not inconsiderable expense, since due to the typical installation situation of boilers for assembly work on the boiler rear side little space is available.
  • the invention has for its object to provide a boiler, in particular condensing boiler, of the type mentioned above, which may be compact, easy to maintain and only produces low operating noise.
  • the invention proposes that in a boiler with the features mentioned, the exhaust gas collection chamber is located at or near the front of the boiler and the cover device includes a silencer or is designed as such.
  • the arrangement of the exhaust gas collection chamber on the front of the boiler facilitates cleaning access and maintenance access, wherein on the front of the boiler is usually given enough space for assembly work, so that a fitter easily solve the fasteners of the cover device, such as screws, and the cover device and the therein integrated silencer can remove as a unit from the exhaust gas collection chamber.
  • the exhaust gas collecting chamber is then free and can be serviced or cleaned from the favorable front-side working position by a fitter.
  • cleaning and maintenance work on the silencer can be made.
  • the cover device realized as a cleaning cover / muffler subassembly is arranged in the installed state directly on the front side of the heating boiler.
  • the cleaning cover / muffler assembly is also exchangeable in a few simple steps, possibly even against a simple cleaning cover with appropriate connection dimensions, if such a cleaning cover temporarily as a replacement for the z.
  • various boilers can be operated according to the invention for operation with different heating media, such as gas, oil or possibly solid fuels.
  • the boiler is a condensing boiler.
  • the muffler may be an absorption muffler or a relaxation muffler or a reflection muffler or a resonance muffler, or an interference muffler or an active muffler (antinoise principle). Mixed forms of the aforementioned muffler principles can also be used.
  • the muffler in the boiler according to the invention is positioned at a location favorable for the exhaust gas passage in the region of the separate cleaning opening sealed by the cover device. Therefore, the muffler does not need to protrude into the exhaust outlet separated from the cleaning port and the lid device.
  • the silencer is located directly opposite the mouth openings of the exhaust gas trains at the exhaust gas collecting chamber, whereas the exhaust gas outlet is preferably arranged laterally offset therefrom. The sound transported with the exhaust gases to the exhaust gas collection chamber and striking the muffler is efficiently damped.
  • the exhaust gas can flow in the exhaust gas collecting chamber laterally between the mouths of the exhaust gas trains and the muffler to the exhaust gas outlet.
  • the hot gases then flow upwards to the exhaust ducts 17, which open with their inlet openings 19 on the partition wall 26 above in the space area 13.
  • the tubular flues 17 are guided around the combustion chamber 3, so that they can in the heat exchanger region 21 between the boiler housing 1 and the combustion chamber 3 heat to the medium to be heated, usually water, leave.
  • the water flow connection is schematically indicated, whereas 25 denotes the water return connection.
  • the exhaust flues 17 open in the lower part of the boiler on the front side 12, and on the partition wall 26, in the exhaust gas collecting chamber 27.
  • the exhaust gas collecting chamber 27 is closed at its cleaning opening 30 to the outside through the front-mounted lid device 29.
  • the cover device 29 is screwed to the housing 28 of the exhaust gas collecting chamber 27 and has a silencer 32 in its cover recess 31 which is preferably a slot absorber muffler.
  • the operating principle of such a slot absorber muffler is with reference to the operation of modified Helmholtz resonators in the DE 101 51 474 A1 to which reference is made.
  • Schalldämmdorfewed z. B a conventional Dämmmateriageage be provided in the lid 31 of the lid device 29.
  • the exhaust gas introduced into the exhaust gas collecting chamber 27 by the exhaust trains 17 flows via the exhaust gas outlet opening 33 to an exhaust pipe 35 of an exhaust system connected thereto.
  • the sound carried by the exhaust gases flowing to the exhaust gas collecting chamber 27 strikes the muffler 32 in the arrangement shown of the muffler 32 in opposition to the mouths of the exhaust gas trains 17 and is effectively damped there.
  • the exhaust gases can flow in the exhaust gas collecting chamber 27 laterally to the exhaust gas outlet 33.
  • a condensate drain is designated to drain the condensate from the exhaust gas collection chamber down to a collecting container.
