Definitions

  • the invention relates to a body of a heating fluid heating boiler, intended to receive at least one burner and which is at least partially enveloped by a jacket for circulation of said fluid, which constitutes the heat exchanger of the boiler and comprises a pipe for departure and arrival pipe as specified in the first part of claim 1.
  • the fluid used is generally water.
  • the water is distributed from top to bottom according to its temperature, the water in the upper zone having a temperature significantly higher than the water in the zone bottom.
  • the internal wall of the water jacket serves as a heat exchange surface between the combustion gases coming from the burner and the water which circulates in the jacket.
  • the combustion gases in contact with a relatively cold surface undergo the phenomenon of condensation also known as the dew phenomenon.
  • Condensation occurs when the temperature drops below around 55 degrees C, but it is common for the temperature of the return water from radiators or heated floors to be around 20 degrees C.
  • the patent GB-A-894691 describes and relates to a heat exchanger which can, in particular, be arranged in the body of a heating appliance.
  • a heat exchanger which can, in particular, be arranged in the body of a heating appliance.
  • the inventor has adopted a similar arrangement so that the cooled water arrives in the hottest zone, and more particularly a provision according to which the jacket for circulation of the heat-transfer fluid comprises a flow line for the heated fluid, which originates in the lower part of the latter, and an inlet pipe for the cooled return fluid, which opens into the upper part of said water jacket.
  • the jacket for circulation of the heat-transfer fluid comprises a flow line for the heated fluid, which originates in the lower part of the latter, and an inlet pipe for the cooled return fluid, which opens into the upper part of said water jacket.
  • Patent DE-A-3442467 shows a boiler whose distribution of fluid on arrival takes place in several places at the same time.
  • the boiler body according to the invention partly takes up what has just been said about the German document but by combining different connections.
  • the invention further provides a means which makes it possible, on the one hand, to preheat the return water before feeding it into the jacket and, on the other hand, to provide an arrival in the lower or middle zone to avoid errors. of connection due to the strength of the habit of installers.
  • the body of a heating fluid heating boiler according to the invention intended to receive at least one burner and which is at least partially enveloped, as specified above, by a jacket for circulation of said fluid, which comprises in the manner already said a start pipe and an arrival pipe, is remarkable in that the return pipe for the return fluid is connected in the lower or middle part of the jacket and rises in the latter towards its upper part, while it ends so that the fluid is distributed in said jacket in several places at the same time.
  • the inlet duct ends in a geometrically open ring, the latter being provided with a plurality of orifices through which the fluid is dispensed.
  • the starting pipe which originates in the lower part of the shirt rises in the latter to exit therefrom in its upper part.
  • a body 1 formed at least in part by a cylinder arranged vertically and intended to receive, generally in the lower part, a burner (not shown), fuel oil for example.
  • the body 1 is surrounded by another coaxial cylinder 2 with a diameter greater than that which forms said body and which is closed so that a volume is formed between the walls of said cylinders, in which water circulates.
  • This volume thus comprised between the body 1 and the cylinder 2 constitutes a jacket 3 for the circulation of water which envelops the major part of said body 1.
  • the jacket 3 has here a relatively small volume, the height being quite large for a particularly reduced thickness. .
  • the water jacket 3 is provided with an inlet pipe 4 for the return water coming from the heating apparatus of the installation (radiators or the like) and with a departure pipe 5 for the heated water which is sent to said heaters.
  • the inlet pipe 4 is connected in the jacket 3 substantially below its horizontal median plane, and rises in the said jacket by a vertical part 4 ′ to end in the form of a geometrically open ring 4 ⁇ ( Figures 1 to 3).
  • the ring 4 ⁇ is arranged in a substantially horizontal plane and has a plurality of orifices such as 6 intended to distribute the return water in the upper part of the jacket 3.
  • the starting pipe 5 originates in the lower part of the jacket 3, and rises by a vertical part 5 ′ in said jacket 3 to exit in the upper part thereof.
  • Figures 2 and 3 show pipes 4 and 5 arranged diametrically opposite, unlike Figure 1, it is clear that it is for the sake of clarity of the drawings, the connection of pipe 4 relative to the outlet of the line 5 can of course be located in other places than that shown.
