Definitions

  • the present invention relates to a hearth boiler of the type comprising a body intended to be disposed above an open hearth and in which a heat transfer fluid circulates, this body having heat exchange surfaces between said fluid and said hearth, and being connected to supply and evacuation pipes for said fluid, themselves linked to an external central heating circuit and / or a domestic hot water circuit.
  • the object of the present invention is essentially to remedy this drawback of known boilers and to considerably increase the heat exchange surfaces between on the one hand the flames and the combustion gases emanating from the hearth and on the other hand the heat transfer fluid. , and this without increasing the external dimensions of the boiler.
  • a hearth boiler is essentially characterized in that said body is equipped with internal combustion chambers capable of being traversed by flames and combustion gases emanating from said hearth, and the walls of which constitute said heat exchange surfaces, the spaces delimited between said chambers constituting an internal circulation circuit for said heat transfer fluid, and in that it is mobile, removable, provided with its own drawing device and with a smoke collector, the draft is adjusted automatically by a key controlled by a thermostatic probe or is manually actuated by a joystick, the upper part of the boiler being removed, constituting an inspection hatch giving access to the smoke collector, the combustion chambers, a automatic air vent and a safety valve.
  • the boiler object of the invention has the following characteristics and advantages: it is an open hearth boiler using fluids as heat transfer agent. Internal combustion takes place in the numerous combustion chambers whose open downward shape can be conical to brake the combustion gases and hot fumes, forcing them to lick their internal wall, thus enhancing combustion and increasing the exchange caloric.
  • the bottom of the boiler can be characterized by its parabolic shape, thus designed to collect. channel and concentrate the combustion gases, flames and hot fumes inside the boiler, where the heat exchange takes place.
  • the exchange is done by fluid according to a forced circuit by baffles through the whole body of the boiler around multiple combustion chambers, which makes it possible to obtain a large caloric surface compared to the diameter of the boiler.
  • the combustion chambers open into a smoke collector located at the top of the boiler.
  • the collector In its rear part, the collector is provided with a drawing device with automatic adjustment by a spiral type thermostat which, when expanding, acts on the drawing key located above the device. This setting promotes rational fuel consumption.
  • a manual position allows, thanks to the complete closure of the draft, the use of the chimney in continuous fire.
  • the upper part of the boiler constitutes an inspection hatch giving access to the automatic and manual draft device, the smoke collector, the combustion chambers, an automatic vent valve and a safety valve.
  • a suspension device integral with the boiler, allows the latter to position itself automatically, as close as possible and directly above the heat source by gravity according to the evolution of the fire in the fireplace.
  • This sliding suspension device is compensated by a spring which reduces the vertical pressure of the boiler on the logs. It conceals the connection pipes. It has an interlock which keeps the boiler in the high position for fuel supply to the hearth.
  • An articulated bracket supports the sliding suspension device, secured to the boiler by its supply pipes. It is fixed to the back wall of the chimney in the upper part of the hood. The articulation of this bracket allows lateral movement of the boiler, which offers the user the possibility of better following the horizontal evolution of the wood fire or clearing part of the hearth for other purposes (rotisserie , grill .). These horizontal and vertical movements of the boiler are possible because it is connected to the central heating circuit by means of flexible pipes tested under the conditions of heat and pressure.
  • connection of these hoses is made by means of watertight hydraulic connections called rapid type, which allows the immediate removal and replacement of the boiler and its suspension device, providing the following advantages: clearing of the hearth for the use of a grill, rotisserie, sweeping, use of the same boiler in various chimneys previously equipped with the same connection device (second homes).
  • FIG. 1 shows the boiler characterized by the curved lateral body 12, the specially studied shape of which offers the following particularity: the part below the axis AB makes it possible to recover the calories by exchange in contact with the flames, while the upper part of this axis returns these calories by radiation in the room.
  • These combustion chambers open into a smoke collector 6 regulating its flow rate by a draft key 20 actuated either by a thermostatic probe 8 or by a lever 19.
  • the upper part of the boiler receives an automatic vent valve 7 and a valve. 5.
  • the upper part of the boiler constitutes an inspection hatch 4.
  • the boiler is suspended by its own cold 2 and hot 3 supply pipes, extended by hoses 17 and fittings 18, on a sliding device (Figure 3) provided with a locking system 14 and a compensating spring 13; this device is attached by a ring 15 to an articulated bracket 21 ( Figure 2).
  • the device according to the invention constitutes with the hearth fire a real boiler which covers, captures and stores the flames and the gases in the vertical combustion chambers 9 around which the exchange with the fluid 10 takes place, the circuit of which is forced by baffles 16 welded vertically between the combustion chambers.
  • This boiler whose body represents the shape of a pot, can be made of copper, whose conductivity and radiation properties are excellent.
  • the evacuation of the burnt gases is controlled by a drawing key with automatic and manual adjustment ( Figure 6) closing the evacuation duct located in the upper part of the boiler on its rear face.
  • the boiler was designed mobile by means of a sliding suspension ( Figure 3) made of wrought iron with a spring 13 to control the pressure of the boiler on the logs.
  • a locking system 14 keeps the boiler in the high position for supplying the fire with fuel.
  • the boiler is made integral with this device by the supply pipes, recommended in brass, and fixed by flanges on the back of the device, which conceals them.
  • An articulated bracket (figure 2) fixed to the back wall of the chimney by means of two screws, to which the boiler-suspension assembly is hung, allows lateral movement of the boiler.
  • the technical characteristics of the device according to the invention make it a full-fledged high performance boiler, justifying its use as a main boiler. It can also be used as a replacement for an existing boiler.
  • the high temperatures obtained inside the combustion chambers mean that the boiler is self-cleaning and does not require any maintenance.
  • the design of the boiler allows it to operate as a thermosyphon; however, its high efficiency justifies the use of a circulator.
  • domestic hot water is obtained from a tank independent of the device according to the invention.
