Definitions

  • the present invention relates to a boiler hearth device.
  • the device according to the invention makes it possible to significantly improve the oxidation of the fuel, and to increase the efficiency of the hearth, whatever the atmospheric pressure.
  • This device is in fact, according to a first characteristic, inclined relative to the horizontal plane, which, in combination with the characteristics listed below, causes a rotation of the combustion gases favorable to efficiency.
  • the burn pot has two sections, the temperature obtained in the narrowest part being higher than in the other part.
  • the device comprises two chambers (delimited by the exterior of the combustion pot and the interior of the exchange envelope) of different volumes, in which combustion and heat exchange take place, the rotation combustion gases taking place in the chamber of larger section.
  • the rear of the hearth is completely submerged, which favors the rotation of the gases and increases the efficiency.
  • the rear wall of the boiler remains cold, an appreciable advantage for its installation.
  • the hearth has two vertical smoke ducts, possibly with a double jacket, tangent to the exchange jacket, which make the combustion process insensitive to variations in atmospheric pressure.
  • the exchange area of the device of the invention is maximum: the heat exchange takes place not only on the periphery, but also on the bottom of the exchange envelope.
  • Figure 1 shows, in longitudinal section, the device according to the invention.
  • FIGS 2 and 3 show, in cross section, the same device.
  • the device of the invention operates as follows:
  • the burner (17) located at the front of the fireplace initiates the exothermic oxidation of the fuel.
  • the burn pot (1) brought to a temperature of around 700 ° C, becomes incandescent in a few seconds. Due to the structure of the device described above, the production of unburnt products (usually originating either from a poor air / fuel dosage, or from the viscosity of the fuel, or from a malfunction of the burner) is minimized. The efficiency of exothermic oxidation is therefore optimal.
  • the heat thus released directs the hot gases and particles to the inlet of the burn pot (1). These then enter the first chamber (4) of the hearth, in which the oxidation continues.
  • the fraction consisting of unburnt and water vapor decreases until it becomes undetectable. In the absence of water vapor, the risks of sulfuric acid formation and, consequently, of corrosion of the hearth, are eliminated.
  • the combustion gases then enter the second chamber (5) of the hearth and propagate to the bottom of the exchange envelope (2).
  • the device according to the invention is intended for both domestic and industrial uses.
