Definitions
- the present invention relates to a scalable heating system having the particularity of having several different applications. (See fig. 1 and fig. 2).
- the basic function being a stove, it can be converted into a boiler intended for heat and circulate various fluids (Water, oil) to heating elements such as radiators or any other radiating system.
- This heating system can use either solid fuels, such as coal, wood, or liquid fuels such as fuel oil or gaseous fuels.
- This invention overcomes the above-mentioned drawbacks insofar as the system accepts various types of fuel through very adaptive simple.
- This heating system in its basic function, consists of an element standard, unique and monobloc called "cell” as shown in perspective fig. 3.
- This specifically shaped cell encloses the hearth where the fuel is consumed.
- This single cell is partitioned by a front face (fig. 6), fitted with a door main (fig. 1.1 and fig. 2.2) and a rear face (fig. 7) in which is arranged, among other things, an opening intended to receive the evacuation conduit for smoke (fig.7.3) and pre-equipped to receive a boiler (fig.8, fig.9 and fig.10) in the case of use in boiler mode.
- the assembly is capped by a cover as shown in FIG. 11.4.
- the front face (fig. 6) is fitted with a movable main door (fig. 1.1) mounted on side hinges. This opening allows the introduction of fuel.
- a single cell thus equipped corresponds to the minimum of power.
- the increase of this heating power can be achieved by adding one or more cells arranged after the first (fig. 13)
- This assembly is carried out, after dismantling of the rear face, by bolting a second cell behind the first (fig. 14 and fig. 15).
- the basic monobloc cell has at each of its ends of pierced square fins (n ° 5).
- the triple role of these angle fins is to ensure the rigidity of the assembly, during assembly (fig. 13), so that that the bending force exerted on the assembly is equivalent to that exercising on a single cell since each of them rests on the ground, it is also to seal the assembly and it is also to spare, after fixing the hood, a space in which the circulation of outside air is forced (fig. 11).
- Transformation of the system to switch from solid fuel (coal, wood) to a liquid fuel (fuel) or gaseous, is carried out by replacing the door main of the front face (fig. 1.1) by another (fig. 2.2) fitted with a burner suitable using liquid or gaseous fuel.
- a boiler (fig.8, fig.9 and fig.10) is fixed on the rear face of the assembly (fig.17.6).
- the cold fluid enters the coil (fig. 19) located in the lower part of the cell. After having thus passed through this coil, it enters the boiler (fig. 9.7 and fig.10.7) in order to be brought to the desired temperature. The fluid thus heated is then ready to irrigate the elements of use such as radiators and water tank hot.
- the volume of the boiler located on the rear side to obtain the desired power.
- the present invention in its basic composition and as drawn in its together (fig. 1 and fig.2), is composed of:
- a main cell (fig. 3).
- Ducts (fig.4.8 and fig.5.8) intended to accommodate the coil in which the fluid passes into the "boiler" configuration.
- the front face (fig. 6) has the function of sealing off the face front of the cell while receiving either a so-called main door, glazed or full (fig. 1.1) in the case of solid fuel (wood, charcoal), i.e. a door main pledge of the burner in the case of fluid or gaseous fuel (fig. 2.2).
- the front panel also receives the secondary door giving access (fig. 1.9) to the ashtray (fig. 20, fig. 21 and fig. 22).
- the front side of the ashtray receives the wheel draw (fig.20.10, fig.21.10 and fig.22.10). It should be noted that in the event of functioning by means of a liquid or gaseous fuel, the function of said wheel becomes irrelevant and it remains permanently closed.
- This ashtray receives a selective grid (fig. 21.11 and fig. 22.11), arranged longitudinally with respect to the axis of the cell, intended to stop, on the one hand, embers still likely to radiate effectively in the cell's hearth and on the other hand, those whose combustion is completely carried out and which can go through said grid to go into the bottom of the ashtray provided for this purpose.
- a selective grid fig. 21.11 and fig. 22.11
- the ashtray which equips each cell is provided along its length with hollow ducts with diamond-shaped section (fig. 21.12 and fig. 22.12). It also has anterior side (fig.20.13, fig.21.13 and fig.22.13) and a posterior side (fig. 21.14 and fig. 22.14).
- the front side receives a wheel which controls two separate openings: one of these openings gives access to the primary air which enters the fireplace (fig.20.15 and fig.21.15), the other opens the access to the primary air to the hollow ducts (fig. 20.16 and fig. 21.16).
- These hollow conduits are arranged parallel and longitudinally so as to that two opposite edges determine a vertical plane.
- the upper walls are full, allowing the ashes to fall to the bottom of the ashtray without clog the duct.
- the lower walls are drilled (fig. 21.17) so that that the primary air can penetrate and favor the combustion of particles not totally consumed retained on the ashtray grate (fig. 21.11 and fig. 22.11).
- the ashtray is designed so as to fit in series and end to end with the ashtray of another cell.
- the rear face (fig. 7) also has the task of partitioning in a way seals the rear face of the cell while receiving the exhaust fumes via a baffle (fig. 23 and fig. 24) imposing the passage of smoke at a point precise (fig. 24.18) where the ducted, heated secondary air arrives (fig. 24.20) which causes them to re-burn.
- the intake of this secondary air is regulated by one or two taps, having the same functions, (fig. 24.19) fixed on the rear face of the cell.
- the rear face (fig. 25) of the cell receives a support (fig. 26.21) allowing the installation of said baffle (fig. 27.22).
- This circular-shaped boiler including the inner fins (fig. 8.24) and external (fig. 8.25) are designed to promote energy capture thermal function, has the function of receiving the fluid intended to be conveyed in the radiating elements.
- the plugs (fig. 16.23) are unscrewed to allow the elements (fig.9.7) of the boiler to be inserted.
- Figure 18 shows the assembly of the boiler (fig. 8) as well as the baffle (fig. 18.22).
