Definitions

  • the invention relates to a heating boiler with a combustion chamber, preferably designed as a lintel combustion chamber, which is surrounded by a jacket space which defines a heat transfer medium and is delimited by an inner wall and an outer wall of the boiler and is assigned to the radiation zone, has a chamber floor and can be connected to a chimney via an exhaust pipe and exhaust pipes is.

  • Such boilers and in particular boilers with lintel burners are known and in use, so that no special written reference is required in this regard.
  • the basic principle of such boilers is that the downward combustion chamber is followed by hot gas flues which end in an exhaust gas collection chamber.
  • the known constructions are complex and expensive in order to achieve the desired results with regard to the best possible use of fuel.
  • the invention is therefore based on the object to improve a boiler of the type mentioned in such a way that fuels with good efficiency can be used with a simple construction of the boiler.
  • Boilers designed according to the invention can be designed both as low-temperature boilers and as boilers with condensate collection and possibly condensate drainage.
  • the design and dimensioning is chosen so that the heating gases cooling on their way to the flue gas chimney do not fall below the dew point. If the design is such that the exhaust gases are cooled below the dew point, the boiler is equipped with an appropriate exhaust pipe or drip pan.
  • the bottom of the combustion chamber in particular the lint combustion chamber, is essentially flat and is covered with insulating materials.
  • the combustion chamber floor has a sheet metal shape, which forces the warm exhaust gases to be conducted near the cooling fins.
  • the bottom of the lintel combustion chamber separates the warm radiation zone of the boiler from the convection part of the boiler.
  • This causes good heat transfer to the inside walls of the boiler, which are provided with cooling fins.
  • the heat absorbed by the cooling fins is dissipated over a large area through the inner walls of the boiler and the guide fins attached to the heat transfer medium.
  • the heating gases are cooled down, and each After the boiler has been designed, the heating gases can leave the boiler at a temperature above the dew point or as exhaust gases cooled below the dew point, in which case the flue gas pipe is designed as a condensate collecting trough.
  • the flue gas pipe with cleaning opening which is provided with a gas-tight flange connection to the boiler.
  • the exhaust gases are conducted in a gas-tight line to the chimney via this exhaust line and the supply line to the chimney designed as a pipeline. If the boiler is not operated as a low-temperature boiler without condensate failure, but rather as a boiler with flue gases that have cooled below the dew point, the resulting condensate liquid is fed into the condensate container and from there it is recycled or disposed of.
  • Fig. 1 is a sectional view of a first embodiment of the
  • the boiler shown comprises a burner flange 1, a lint combustion chamber 2 with the inner wall 3 of the combustion chamber and the outer wall 1 1 for receiving the heat transfer medium 4, the lint combustion chamber bottom 5 with the overflow openings 6 at the edge of the combustion chamber bottom 5, the cooling fins 7 with in Flow direction of the exhaust gas inclined slots, the guide ribs 8 for the heat transfer medium 4, the heat transfer line 9 and the heat transfer line 10.
  • the flue gas pipe 12 with a cleaning opening 13 is arranged under the boiler.
  • the space under the exhaust pipe 12 is provided for the optimal reception of a condensate container 14.
  • the exhaust gases are conducted to the chimney in a gas-tight exhaust pipe 12 and the gas-tightly connected exhaust pipes 15.
  • the distance between the combustion chamber base 5 and the cooling fins 7 can be defined in a defined manner by means of spacers. It is also possible to define the free passage cross section of the overflow opening 6 in a defined manner, in particular by specifying the diameter of the combustion chamber floor, this specification being able to be made as a function of the desired mode of operation of the boiler.
  • the good efficiency of the boiler is in particular a consequence of the fact that the cooling fins 7, which have a large heat exchanger area due to their dense packing, are directly connected and preferably welded to the combustion chamber inner wall 3 and the other side of the combustion chamber inner wall is connected to the guide fins 8, is connected in particular by welding, so that optimal heat transfer properties are obtained. Since the guide ribs 8 have a helical shape and the flow cross section becomes larger towards the top, the best possible heating of the heat carrier 4 can be achieved.
  • Additional heat transfer ribs can be provided between the guide ribs 8, which protrude into the flow channel, but do not extend to the outer wall 11 of the boiler.
  • a targeted swirling of the heating gases can be achieved on their way to the exhaust pipe. This promotes heat transfer to the fins 7 and thus contributes to increasing the efficiency.
  • the dimension of the constriction 6 in the radial direction can be in the range of approximately 3 to 10 mm. This dimension is preferably about 5 mm.
  • the slots provided in the cooling fins 7 prevent, on the one hand, the occurrence of stresses which may lead to tearing effects and, on the other hand, due to their tendency, ensure that any condensate which may occur is directed radially inwards and can drip off there at the beginning of the open slot.
