Definitions

  • the invention relates to a radial burner for condensing boilers and more specifically relates to the positioning of the burner inside the combustion chamber.
  • the combustion chamber in this type of device contains a blown air burner whose gases are emitted radially and pass through the cylindrical layer of water tubes with which heat exchange takes place.
  • the tubes are obviously dimensioned and arranged so as to obtain a laminar gas flow, and large exchange surfaces with them.
  • These tubes are themselves housed in a sealed chamber consisting of a shell, the upper part of which communicates with a discharge duct.
  • the combustion products are therefore collected by this shell which forms an outer casing autor of the combustion chamber.
  • This shell constitutes a cylindrical box autor of the layer of water tubes centered on the same vertical axis which is also the axis of the radial burner.
  • Such an apparatus is known from FR-A-2,371,642.
  • the invention proposes a solution which avoids this drawback by using a means suitable for breaking this axial symmetry of the burner-combustion chamber to thereby avoid successive reflections of sustained sound waves.
  • the radial burner is disposed slightly off-center with respect to the axis of the chamber, so that the waves emitted do not come from this axis and therefore do not regularly reflect on the water tubes or the outer shell.
  • the sustained waves then have a damping coefficient such that the noise generated during ignition weakens very quickly.
  • the burner is engaged in an off-center orifice provided in a disc-shaped support plate fitting at the base of the combustion chamber.
  • FIG. 1 shows an exchanger delimited by a cylindrical shell 1 which rests on a lower base 2 pierced with orifices suitable for the passage of conduits 3 and 4 for the arrival and departure of water, and for the tubing 5 for admitting the gas mixture to the radial burner 6 disposed in the exchanger.
  • a cylindrical shell 1 which rests on a lower base 2 pierced with orifices suitable for the passage of conduits 3 and 4 for the arrival and departure of water, and for the tubing 5 for admitting the gas mixture to the radial burner 6 disposed in the exchanger.
  • the water tubes 7 which form a fully self-contained cylindrical sheet of the burner 6, their shape and their spacing being determined so as to have large exchange surfaces with the combustion gases.
  • Water circulates in the tubes of the sheet from a lower distributor ring 8 to an upper distributor ring 9 and vice versa, thanks to a set of baffles not shown located in the rings.
  • the air-gas mixture coming from a mixing chamber 12 is blown towards the burner by
  • the cylindrical shell is capped with a cover 11 provided with an orifice 13 for the evacuation of the burnt gases.
  • the mixing chamber 12 disposed parallel to the shell is supported on an extension of the lower base 2 and is connected to the tube 5.
  • the burner 6 is not centered in the middle of the combustion chamber but that, on the contrary, it is slightly off-center with respect to the axis of revolution BB 'of this chamber.
  • the burner support plate which is in the form of a disc 14 is provided with an orifice 15 which is off-center with respect to said axis BB '. This plate fits at the base of the combustion chamber in the lower base 2.
  • the figures represent the off-center burner on the side opposite to the mixing chamber 12, but it could also be shifted in another direction.
  • the disc 14 also serves as a support for the spark plugs 16 for ignition of the burner, which is made possible by the fact that the orifice 15 is off-center and that the plate 14 thus has a crown which is wider on one side than on the 'other and which can therefore serve as a base for said candles.
