Definitions
- Boiler hearth device with very high combustion and exchange efficiencies, characterized by its inclination, its immersion in a fluid or in a liquid, and its double-wall funnel ducts.
- 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 cctribusticn gases favorable to the return.
- 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 outside of the distribution pot and the interior of the exchange envelope) of different volumes, in which the combustion and thermal exchange occur, the rotation combustion gases taking place in the chamber of larger section.
- the rear of the hearth is completely submerged, which promotes the rotation of the gases and increases the efficiency.
- the rear wall of the boiler remains cool, an appreciable advantage for the installation.
- the hearth has two vertical jacketed flue pipes, tangent to the exchange envelope, 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.
- Figures 2 and 3 show, in cross section, this male device.
- the structure and operation of this device are set out below, with reference to these drawings and to the enclosed nomenclature Structure of the device
- the device of the invention consists of the following parts:
- a first chamber (4) delimited by the largest outside diameter of the ccmbusticn pot (1) and the inside of the exchange envelope (2).
- the inventive device works as follows:
- the burner (17) located at the front of the hearth initiates the exothermic oxidation of the fuel.
- the fuel pot (1) brought to a temperature of about 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 mixture, or from the viscosity of the fuel, or from a poor functioning of the burner) is minimized. Made it from exothermic oxidation and therefore optimal.
- the heat thus released directs the hot gases and particles to the inlet of the combustion chamber (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 detectable. Eh absence of water vapor, the risks of formation of sulfuric acid and, consequently, of corrosion of the hearth, know annihilated.
- the combustion gases then enter the second chamber (5) of the hearth and propagate to the bottom of the exchange envelope (2).
- the space (8) delimited by the external envelope of the boiler (9) and the exterior of the exchange envelope (2) can contain an air exchanger for the production of a model of boiler with "pulsed air".
- the device according to the invention is intended for both domestic and industrial uses.
