Definitions

  • the present invention relates to a hot water boiler using solid fuel in the form of aggregates: coal pellets, plugs, wafers or various briquettes of coal, wood, straw, sawdust, etc.
  • the object of the present invention is to provide a boiler which is free from the drawbacks indicated and which on the other hand has a whole series of advantages: simple design, calorific efficiency clearly superior to that of current boilers, combined with a supply system, 'activation of fire and automatic de_endering of great reliability and inexpensive implementation eliminating any manual intervention.
  • Another object of the invention is to provide a boiler which comprises an automatic feeding part of the burner from a hopper containing the fuel and by means of a double piston back and forth forming an integral fire stop in the rest position, and which is powered by a motor.
  • electric linear motion cylinder type electric linear motion cylinder type.
  • Another object of the invention is to provide a boiler which comprises a boiler body of the type with vertical tubular exchangers embedded in a water cylinder of conventional type but whose calorific efficiency is improved by a demountable domed deflector whose cavity can be filled with a load of refractory material in order to increase the heat inertia.
  • Another object of the invention is to provide a boiler in which combustion is improved by admission of air above the burner inlet by a deflector and a grid with high calorific inertia.
  • a boiler according to the invention has the following separate parts: the automatic feed, the burner, the body of the boiler.
  • a - the automatic feed comprises, according to FIG. 1: the fuel storage hopper 1, the feed mechanism and the drive motor with its box or control members.
  • This assembly mounted on a tubular frame with adjustable feet is connected to the boiler burner orifice by bolts or other fixing.
  • the fuel storage hopper 1 in the form of a pyramid or cone throne ends at its base with a chute 2 of section adapted to the shape of this part of the hopper and comprises two baffles 3 and 4 limiting the action of the fuel charge column on the supply corridor.
  • the baffle 3 is articulated at 5 and adjustable for closing the hopper and for adapting the fuel intake to the desired conditions. It is possible to provide that the other baffle 4 is also articulated, or that the two baffles are articulated.
  • the capacity of the hopper 1 can be increased by adding a raise to its upper part.
  • the supply of the hearth is carried out by a piston 6 circulating in a corridor 7 of roughly the same section and animated with a back and forth movement, which ensures the connection between the chute 2 and the burner inlet 8.
  • the piston 6 In the withdrawn position, the piston 6 discovers an opening 9 made in the upper part of the passage 7 at the base of the chute 2 and the fuel then enters the passage.
  • the pushing movement of the piston 6 pushes the fuel towards the inlet of the burner 8; at the end of the stroke, the piston is positioned at the inlet of the burner and constitutes a fire protection element.
  • a space 11 is provided between the top of the piston 6 and the vault of the corridor 7.
  • a horizontal shelf 10, of width equal to that of the corridor at this level extends the piston backwards over a length at least equal to the stroke of the piston.
  • a fuel blanket spreads out in the cavity 11 between the shelf 10 and the top of the corridor 7 thus eliminating the risk of jamming.
  • a stop 12, fixed to the rear of the opening 9 gradually eliminates this mattress of fuel towards the front of the piston during the movement of withdrawal of the latter.
  • the feed mechanism is driven by a motor 13 of the known type electric actuator motor, that is to say that the rotary movement is transformed into linear movement by a two-way screw nut system of step which is advantageously controlled by any suitable electrical or electronic control and command device, the constituent elements of which are partly or wholly grouped together in a so-called control panel or box (not shown).
  • the burner 8 shown in section in Figure 1 and seen from above in Figure 2 is advantageously made of stainless steel or steel covered with a refractory lining or any other suitable material. Its inlet width is adapted to the width of the feed corridor 7. The burner then gradually widens towards the center of the boiler and its bottom is perforated to allow the admission of combustion air by means of a cavity 14 under the burner and connected to the outside to a fan 15 preferably fixed on the chassis of the hopper.
  • This air admitted to the burner can be, as desired, fresh air taken from the boiler, or air heated by passage through a box located under the burner.
  • a guide piece 16 made of stainless steel preferably, has grooves (three shown) in which fingers 17 of the same section slide, integral with the piston 6.
  • the fingers move over the bottom of the burner for about 4 / 5ths of its length; in their back and forth movement they break the product of combustion and fire the fire.
  • the guide piece 16 prevents the embers, during the recoil, from entering the feed passage 7, while in the pushing movement the fingers revive the combustion and gradually drive the burnt residues out of the burner towards the ashtray.
  • the boiler is specially designed to make the best use of the advantages and features described above of the supply system and the burner.
  • the heat exchanger tubes are fitted with smoke retarders 23.
  • This new design of the deflector constitutes a particular feature of the invention.
  • the upper part of the exchangers opens into a smoke evacuation box, allowing an additional heat exchange above the water cylinder.
  • the lower box 19 contains the ashtray drawer 25.
  • a large insulated door allows access to the ashtray and easy disassembly of the burner.
  • the feed mechanism comprises, according to FIG. 3: an upper pre-feed passage 52, at the base of the hopper, inside which a pusher 53 circulates, which has a. conformation which provides a space between its upper face and the vault of the corridor 52, allowing it to pass through the column of fuel leaving the hopper, without jamming.
  • the movement of the pusher 53 is transmitted by the introduction piston 6, the stroke of the pusher 53 being limited towards the front by stops 54.
  • the front movement of the pusher delivers the fuel to a cavity 55 which communicates with the passage of introduction 7.
  • the section of the introduction piston 6 corresponds, apart from the operating clearance, to the section of the passage 7 in which it moves.
  • the piston 6 is positioned at the inlet of the burner 8 and completely closes this orifice.
  • the tablet 10 In the rear movement of the piston 6, the tablet 10 fully opens the base of the cavity 55. The dose of fuel contained in this cavity pours into the passage 7, in front of the piston, while the pusher 3 moves back to discover the orifice hopper.
  • All the constituent elements of the feed mechanism as well as the combustion activation fan 15 are mounted on a frame connecting to the orifice of the burner 8, by bolts or other fixing.
  • the hopper 1 is mounted on adjustable feet and its orifice adjusts in the upper opening of the corridor 2.
  • a second variant of the device described above concerns the improvement of combustion in the furnace hearth.
  • the boiler object of the invention can be used for central heating as for any domestic or industrial hot water production.
