Definitions

  • the invention relates to a lint burner boiler with exhaust gas temperature control according to the preamble of the main claim.
  • flaps which can be regulated as a function of temperature and which can be adjusted using rods, servomotors and also bimetal elements.
  • flap controls work more or less satisfactorily. "More or less” because no appropriate measures have been taken on the boiler side, ie no influence has been taken on the effective heat transfer surface, which inevitably has an effect on the flue gas temperature.
  • the invention is therefore based on the object to improve a boiler of the type mentioned in such a way that a more optimal exhaust gas temperature control can be achieved with simple means and measures.
  • This inventive design ensures that in times of lower heat requirements, i.e. low burner output, the heating or flue gases can flow out to a large extent through the flue gas duct exposed when the flap is open, but care is taken to ensure that both the flue gas duct and the flue gas duct Resistance and the heat transfer area are significantly reduced, so that the heating gases flowing through there can only emit little heat and get into the fume cupboard at a relatively high temperature level. From the boiler design, this can be achieved simply by simply omitting some of the longitudinal ribs in the area of the flue gas duct.
  • the width and cross-sectional shape of the closure flap is adapted to the cross-section of the flue gas duct, and the flap is located on the exhaust side behind the flue gas duct on the bimetal controller arranged there and, because it is arranged in a relatively low-temperature range, can be formed from a correspondingly thin sheet metal segment with a relatively low weight be that can be easily moved by a known bimetal controller.
  • the novel design means that the heating surface is lost due to the rib-free flue gas duct, but on the other hand no additional heating surface has to be provided because the flue gas flows out through the other, normally dimensioned heating gas flues when the flap is closed, with a higher flow resistance and higher speed. but which increases the heat transfer on these heating surfaces.
  • the flue gas duct which is free from longitudinal ribs, is arranged under the mouth of the flue gas connection and the lever-like bimetal regulator with its free one End is fixed in the exhaust pipe.
  • the mouth of the flue gas outlet is rectangular in cross-section and is arranged with its large axis transverse to the longitudinal axis of the boiler.
  • the relatively wide outflow cross section of the flue gas duct can be better detected.
  • the lower boundary edge of the junction is advantageously designed in the manner of a loop.
  • the lint burner boiler consists of a water-bearing housing 1 with a combustion chamber 2, which is surrounded by a ring-shaped, leading to the flue gas outlet, by a plurality of longitudinal ribs 3 divided into individual lines 4 heating gas line 5, with a flue gas temperature-dependent ver in the area on the flue side adjustable shutter 6 is arranged.
  • a flue gas temperature-dependent ver in the area on the flue side adjustable shutter 6 is arranged.
  • Such boilers are known in principle. "In principle” because such exhaust gas temperature controls, as far as is known, are only used on boilers with a horizontally oriented longitudinal axis.
  • a flue gas duct 7 free of longitudinal ribs is arranged or provided in front of the flap 6 in the heating gas flue 5 with a width which corresponds at least to the width of three individual flues 4, that the width and cross-sectional shape of the flap corresponds to the cross section of the flue gas duct 7 and that finally the flap 6 is arranged on a bimetallic regulator 8 arranged behind the flue gas duct 7.
  • the gas discharge pipe 9 is located on the side next to a collection chamber 11 which surrounds the burner connection area 10 in a ring 9 attached.
  • the mouth 12 of the flue gas connector 9 is rectangular in cross section and is arranged with its large axis 14 transversely to the longitudinal axis 15 of the boiler.
  • the wall of the flue gas connector 9 is designed in such a way, as can also be readily seen from FIG. 2, that there is a circular cross section of the flue gas connector 9 on the chimney side.
  • the lower boundary edge in the mouth 12 is advantageously formed in the form of embrasures 17, as can also be seen in FIG. 2.
