Definitions

  • the invention relates to a sealed gas boiler with forced draft and specifically relates to a new arrangement of the sealed enclosure provided for the evacuation of the burnt gases.
  • boilers in which the heat exchanger consists of a cylindrical bundle of vertical tubes interconnecting end collectors, exchanger which delimits a combustion chamber through which the flame of a burner which transfers heat to the water circulating in these tubes.
  • this exchanger is disposed vertically inside an insulating envelope, the burner being disposed just above the combustion chamber.
  • the invention therefore aims to eliminate the aforementioned difficulties inherent in these devices and for this purpose offers a particular arrangement characterized in that the sealed and anti-noise shell enveloping the cylindrical exchanger is suspended in the upper half of the frame.
  • the boiler to a horizontal plate fixed to the frame above which the air intake and combustion product evacuation ducts are arranged, as well as the fan, and the central inlet opening of the exchanger at level of said plate is in the axis of the outlet pipe of the fan, and the periphery of the shell at the level of the plate also includes the outlet for the combustion products collected by the sealed shell which passes through said plate and is at least approximately in the axis of the duct for discharging said products from the boiler.
  • the boiler shown essentially comprises a backrest 2 for its attachment to the mounting wall of the room, and side frames 3 having large openings, these elements 2 and 3 constituting the frame 1 of the device.
  • a horizontal plate 4 which is also supported by an angle 5 arranged transversely to the frames 3.
  • This horizontal plate 4 slightly offset laterally relative to the axis of the frame 1 supports a heat exchanger 6 consisting of a cylindrical layer of water tubes 7 arranged vertically and interconnected by a lower circular collector 8 and by an upper circular collector 9, these tubes thus forming a cylindrical combustion chamber 10.
  • the heat exchanger 6 is provided with a central opening 11 at its upper part, on the other hand it is closed by a bottom at its lower part.
  • the horizontal plate 4 comprises at the base of the central inlet orifice 11 of the exchanger 6, a cutout 12 for, on the one hand, the positioning in said exchanger 6 of a burner 13, for example of the torch type, the flame is oriented downwards and on the other hand the passage of the pipes 14 for the inlet and outlet of water from the exchanger.
  • the heat exchanger 6 is wrapped in a waterproof and anti-noise shell 15 of substantially oval shape which is removably supported under the horizontal plate 4 by clips 16.
  • This waterproof shell 15, for example made of molded plastic or produced semi-rigid or flexible analog, present on its upper edge which is applied under the horizontal plate 4 a groove 24 in which is placed an O-ring 25 to ensure sealing.
  • an orifice 26 In the bottom of the sealed shell 15 is provided an orifice 26 for the evacuation of condensates.
  • the sealed shell 15 is offset laterally in the frame 1 and leaves on the side a space for the possible mounting of a sanitary water exchanger, not shown.
  • An upper cover 17 which closes the frame serves as a support for the conduit 19 for the admission of fresh air inside which and coaxially is arranged in known manner another conduit 18 of smaller diameter for the evacuation of the burnt gases.
  • an air-gas mixing chamber 27 which is - by its upper part -, directly in communication with the duct 19 for admitting fresh air by means of said distribution box 20 and - by a lateral face -, connected to the inlet orifice 28 of a fan 29 by means of a tube 30.
  • a gas injector 31 disposed horizontally in the axis of the tube 30 allows the injection of gas and its mixture with air in said tube.
  • the fan 29 is mounted under the upper cover 17 so that its outlet pipe 32 directly connected to the burner 13 is located in the axis of the central inlet orifice 11 of the heat exchanger 6.
  • the movement of air and gas inside these different elements is therefore ensured by the fan 29.
  • the fresh air is sucked in from the outside through the duct 19 and the distribution box 20 into the mixing chamber 27 to form with the gas in said chamber a combustible mixture which penetrates through the tube 30 into the fan 29 before being injected through the pipe 32 into the burner 13 where it ignites.
  • the products of combustion pass through the cylindrical layer of water tubes 7, then are collected in the sealed shell 15 and are then discharged towards the outside by the connection tube 22 and the evacuation duct 18.
  • the shell 15 is produced in the form of a parallelepipedal box also covering the orifice 23 for the outlet of the combustion products.
  • the device thus described by way of nonlimiting example is therefore of reduced size while allowing easy accessibility of the various mechanisms which facilitates assembly, disassembly and maintenance operations.
  • these mechanisms being properly ventilated by the ambient atmosphere and thermally insulated from the hot part by the sealed shell, can be made of common material, in particular with parts of plastic material.
