Definitions

  • Such a heating element equips boilers marketed by the German company BROTJE (JP-A-2374598) under a embodiment in which the fins and the flue gas guide channels are oriented longitudinally, between gas inlet means combustion located at the transition between the front zones and back of the envelope and the gas outlet means combustion formed by an annular collector, transverse arranged around the rear end of the envelope and opening upwards on a box longitudinal smoke, superimposed on the envelope and connected to a drain.
  • This known boiler has advantageous features in that it is possible to size it so that the front end of the flame acts on the transverse wall before the envelope and causes at this level a heating of water by direct exchange, and in that the whole formed by the ferrule and the fins ensures gas guidance combustion backwards along the wall longitudinal of the envelope, and ensures at this level a heat exchange between these gases and water. So this known boiler allows to allocate a significant part of thermal energy produced by combustion at heating of the water which, circulating in a circuit outside the boiler, can be used for any purpose for heating or sanitary purposes.
  • the present invention is, however, set for aim to further improve heat exchange capacities between the combustion gases and the water and, for this purpose, it offers a heating body of the type indicated in preamble, characterized in that the fins and the channels are annular and transverse and in that the input and output means include a collector respective longitudinal serving the canals in parallel.
  • the arrangement of the fins and channels according to the invention makes it possible to considerably increase the length of the path traveled by the combustion gases, at contact of the longitudinal wall or the fins in thermal conduction relationship therewith, i.e. further increase heat exchange capacities between the combustion gases and the water placed in contact with the longitudinal wall, at the rear area of the envelope, naturally without affecting the exchange thermal at the front area thereof, that is to say to recover even more energy thermal produced by combustion.
  • Implementation of the present invention also allows, at capacities equivalent heat exchange, reduce dimensions of the heating body in comparison with the heating body of known boilers, mentioned above, especially in the longitudinal direction, since it is possible to have the same path length of the combustion gases in the rear area of the envelope for a smaller longitudinal dimension from this rear area as well as from the shell, equal transverse dimensions.
  • baffles which lengthen the combustion gas path and force them to in particular along said longitudinal wall and / or the fins, themselves placed in conduction relationship thermal with it, to favor an exchange thermal between the combustion gases and this wall and / or these fins and, through this wall, between the combustion gases and the water that bathes it externally.
  • the fins are for the essentials continue in circumferential direction at with the exception of two respective localized interruptions, diametrically opposite with reference to said axis, rightly a respective input interruption and a respective output interruption, interruptions input being located on the same side of said axis and longitudinally aligned to form part of the input collector and output interrupts being located on the other side of said axis and longitudinally aligned to form part of the collector of exit.
  • ferrule present opposite longitudinal light entry interruptions constituting part of the inlet manifold, which not only ensures direct recovery of combustion gases tending to run along the longitudinal wall in the front area of the envelope, but also the gases of combustion which either because they escaped the chute if such a chute is provided, either because that they are radially cleared from the flame, come in contact with the shell in the rear area of the envelope.
  • This light is advantageously constituted by a longitudinal slot in the shell and facilitating the assembly and disassembly of the ferrule, allowing a reduction in its dimensions transverse by pinching said slot, according to a preferred embodiment in which the ferrule is removably inserted into the envelope.
  • the part of said longitudinal wall corresponding to said area rear presents opposite exit interruptions at minus a longitudinal light constituting part of the outlet collector. This also ensures a recovery as efficient as possible the flue gases leaving the different channels.
  • the interruptions of the fins corresponding to the input manifold have transverse dimensions which decrease backwards and the interruptions of the fins corresponding to the outlet manifold have dimensions transverse which decrease towards the front, which allows ensure optimal distribution of combustion gases between the different channels as they enter these last and an optimal recovery at their exit from these last.
  • the fins can present also localized interruptions, generally smaller transverse dimensions, which on the one hand facilitate the distribution and the liberation of expansion constraints and on the other hand establish between the guide channels an intercommunication allowing gases to pass through a channel which, for example, would become blocked at the neighboring canals.
  • these additional interruptions are provided on each fin in two copies diametrically opposite and placed at right angles to report of interruptions corresponding to collectors input and output, with reference to said axis, but this provision is only a non-limiting example.
  • the fins are integral with said wall longitudinal.
  • the possible baffles of these channels guide can be made of sheet metal refractory in the form of bands inserted into the channels and wavy in cross section.
  • the means for delimit a water circulation chamber in contact with transverse and longitudinal walls, outside of the envelope, are advantageously made in one piece with these walls, in foundry.
  • the shell is preferably common to the different sections of the wall longitudinal of the envelope and presents for this purpose adapted longitudinal dimensions.
  • the front module also includes a section of said longitudinal wall of the envelope, means for delimiting the water circulation chamber in contact with this section, the corresponding fins and the corresponding inlet and outlet manifolds, if although it can also be used without being associated to a rear module, and in this case corresponds to the minimum power offered by modular design.
  • the ferrule is common preference for sections of the longitudinal wall of the envelope corresponding to the front module and the number provided with rear modules.
  • the front module can be in any point conforming to the design heating body unitary, in all its possibilities of realization previously mentioned.
  • a rear module can also present a unitary achievement, grouping the section corresponding to the longitudinal wall of the envelope, means for delimiting the water circulation chamber in contact with this section, the inlet and corresponding outlet and preferably the fins corresponding, if necessary with baffles reported inside the gas guide channels combustion.
  • FIG. 1 we will first refer to Figures 1 to 7, and in particular in Figure 1, where we illustrated schematically a boiler more particularly intended to be integrated into a chimney, as non-limiting example of a boiler capable of include a heating body according to the invention, being understood that such a heating body can be fitted with many other types of boilers for example boiler rooms with external burners or integrated boilers called "suction cups", and that the fuel used can be either fuel oil or gas.
  • This boiler 1 comprises, inside a bodywork 2, for example generally parallelepipedic, a heating body 3 having a longitudinal axis 4, here horizontal, around which the heater 3 presents a general form of revolution. More specifically, the heater 3 is essentially formed of two mutually integral components, to know an envelope 5 and a ferrule 6, each of which itself essentially presents a symmetry of revolution around axis 4.
  • the wall 14 is doubled towards the axis 4 by the ferrule 6, in approximately cylindrical longitudinal tube shape of revolution around axis 4 and defining in this rear zone 17, with the wall 14, an annular chamber 18 for the passage of combustion gases.
  • walls 12 and 14 are lined with a respective wall 19, 20, the wall 9 mutually connecting the walls 14 and 20 around the open end 8 of the envelope 5.
  • door 48 can also delimit internally a sealed circulation chamber of water 22, connected to chamber 21.
  • the wall 14 does not have a diameter constant interior over its entire extent longitudinal, from its connection with the wall 12 to its connection with wall 9, but has two parts corresponding respectively to the area before 16 and to the rear zone 17 of the envelope 5.
  • the wall 14 has a respective part 27,28 cylindrical of revolution around this axis 14, but the part 28 corresponding to the rear area 17 has a inner diameter greater than that of part 27 corresponding to zone 16 and these two parts 27 and 28 are connected to each other by a part 29, in recess, of the wall 14. More precisely, the part 29 of wall 14 is flat, annular of revolution around the axis 4, and forms inside the hearth 15 a shoulder facing back.
  • the ferrule 6 is placed in the extension direct longitudinal from part 27 of wall 14 corresponding to the front zone 17, and rests flat, forward, against part 29 of wall 14, at immediate proximity to the mutual connection of the parties 27 and 29 thereof, by a flat edge 30, annular of revolution around axis 4.
  • the ferrule 6 has the general shape of a tubular wall 31, of revolution around axis 4 and of constant diameter both internally than externally, up to a song rear 32 annular, plane, of revolution about the axis 4, which edge 32 substantially coincides with the wall 9 and is advantageously bordered in the direction of a distance from axis 4 by a flange 33 ring of revolution around it and taking flat support against the wall 9, behind the latter, over the entire periphery of the rear end open 8 of the casing 5 when the ferrule 6 rests moreover, flat, by its song before 30 on the part 29 of wall 14.
  • the shell 6 is produced by forming a refractory sheet, and it is inserted from removably inside the envelope 5 so as to allow its disassembly for cleaning the chamber 18 then its reassembly, or its exchange.
  • the ferrule 6 in the inserted state at the interior of the envelope 5 has a slot longitudinal open 62, extending from edge 30 to its edge 32 and extending over the edge 33.
  • This slot 62 which has a width, measured circumferentially with reference to axis 4, just sufficient to allow him to intervene in the flue gas circuit to be described later, also allows elastic deformation the ferrule 6 in the direction of a reduction in its size transverse to allow its extraction and insertion in relation to the envelope 5.
  • spacers 34 curvilinear or rectilinear oriented substantially circumferentially with reference to axis 4 are arranged for example in extreme areas before and rear of slot 62, which retains them by pinching.
  • the cumulative longitudinal dimension of the spacers 34 is low enough that they don't hinder substantially the passage of combustion gases, in conditions which will be described later.
  • ferrule 6 In the state inserted inside the envelope 5, ferrule 6 is retained therein by a form press fitting, due to its elasticity tending to increase its transverse dimension, helped if necessary for this purpose by the action of the spacers 34, and by support in the direction of a distance from axis 4, from made of this elastic trend, on fins 35 fitted inside room 18 and advantageously made in one piece with part 28 of the wall 14, to define with this part 28 and the ferrule 6 of the channels 36 for guiding the combustion gases to the interior of room 18.
  • the fins 35 could also be reported to inside the envelope 5 without leaving as much of the scope of the present invention, therefore that they would be placed in a conduction relation thermal with the wall 14 in order to transmit in the better conditions the heat of the flue gases to water 22 passing through chamber 21.
  • the fins 35 and the channels 36 that they help delimit are annular and transverse.
  • the fins 35 are annular, flat, of revolution around axis 4 to which they are respectively perpendicular.

  • Interruptions 38 different fins 35 are thus aligned mutually in longitudinal direction, to constitute part of a longitudinal manifold 40 for entry of combustion gases in chamber 18, at the bottom of this last, and the same goes for interrupts 39 of so that these are part of a longitudinal manifold 41 for gas outlet combustion after passing through chamber 18, at the upper part of it.
  • the interruptions 38 and 39 are defined by a flat edge respective 42, 43 of the fins 35, which is oblique by compared to plan 37 from which it is gradually moving away in the meaning of a distance from part 28 of the wall 14, so that the cross section of each interruption 38, 39 has the general form an isosceles trapezium whose small base runs along this part 28 and whose large base runs along the tubular wall 31 of ferrule 6, which facilitates direct production interruptions 38, 39 by molding when, so preferred, the fins 35 are molded in one piece with the envelope 5.

  • the fins 35 are equidistant longitudinally, the fin 35 most close to the open end 8 is placed in the direct extension of the wall 9 and the fin 35 most close to part 29 of wall 14 is placed at a longitudinal distance of this part 29 which corresponds at the mutual longitudinal spacing between two fins 35, but other provisions could also be chosen without departing from the framework of the present invention.
  • each fin 35 is delimited by a respective 44 cylindrical song of revolution around this axis, the diameters of the different edges 44 being identical to and greater than the inside diameter of the part 27 of wall 14, of a value which corresponds substantially to the wall thickness of the ferrule 6 in its tubular part 31, so that this part tubular 31 extends part 27 of wall 14 towards the rear without forming a noticeable dropout inside the fireplace 15.
  • the fins 35 may present, in addition to interruptions 38 and 39 corresponding to the input collector 40 and exit 41, localized interruptions 45 presenting the form of notches arranged in their edge 35, radially with reference to axis 4, on one dimension radial less than that which mutually separates the edges 44 of fins 35 and part 28 of the wall 14.
  • interruptions 45 presenting for example transversely an isosceles trapezoid shape as it is also the case of interruptions 38 and 39, do not provide usually no gas passage function of a channel 36 to each other and essentially serve to absorb the expansion of the fins 36 and to facilitate operations inserting and removing the ferrule 6; however, if one of the channels 36 is blocked, they allow combustion gases to pass from the channel blocked with neighboring canals, that is to say to distribute better in room 18 despite this blockage.

  • fins 135 present in the longitudinal alignment of the interruptions 45 not visible in Figure 8
  • fins 35 of the interruptions 145 in all respects identical to interruptions 45 and performing the same function and in channels 136 of the module 103 as in channels 36 of module 3 can be inserted bands at all points identical to bands 66 to define baffles as in the case of the heating body 3 described with reference to Figures 1 to 7, and more precisely 6 and 7.
  • the heating body formed by the assembly modules 3 and 103 behaves like the body of heater 3 described with reference to Figures 1 to 7, of which would have increased the longitudinal dimensions of the area rear 17 of the casing 5 in which the hearth 15 is bounded peripherally not by the wall longitudinal 14 of it, but by the ferrule 6, then that the front zone 16, delimited by the only module 3 as it is by the heater 3 described in reference to module 3, would remain unchanged.
  • the envelopes 5 of module 3 and 105 of module 103 complete so that part 28 of the wall the of the casing 5 and the wall 128 of the casing 105, placed in the longitudinal extension one of the other and for example having the same diameter, can be considered as two sections of the same longitudinal wall, substituted for part 28 of the wall 14 of the casing 5 of the heating body 3 described in reference to FIGS. 1 to 7, as well as the shell 106 is substitutes for ferrule 6 with dimensions increased longitudinal, to delimit a room transverse annular gas circulation of combustion, fully comparable to chamber 18 of the heater 3 described with reference to Figures 1 to 7 but also larger longitudinally and formed at level of module 3 through chamber 18 thereof and at level of module 103 through chamber 118 thereof.
  • the combustion gas circulation chamber thus formed by the chambers 18 of the module 3 and 118 of the module 103 is divided into annular channels 36 by transverse partitions 35 at module 3 level and annular canals 136 by transverse partitions 135 at module 103, channels 36 and 136 being fed in parallel by a longitudinal collector inlet formed by inlet manifolds 40, 140 and serving in parallel a longitudinal collector of outlet formed of outlet collectors 41,141 such as channels 36 of the heating body 3 described with reference to Figures 1 to 7 are supplied in parallel by the input collector 40 thereof and serve in parallel its output collector 41.
  • module 103 behind the module 3 doubles the trajectory covered transversely, in parallel, by the combustion gases in comparison with the trajectory they travel in the only heater 3 described with reference to Figures 1 to 7, once we adopt a number and a dimensioning of the fins 135 and of the channels 136 substantially identical in number and sizing fins 35 and channels 36.
  • This module before would have chute 47. So this front module would be completed by longitudinal juxtaposition, towards rear, a number of rear modules at any point identical to the module 103 previously described, and whose water circulation chambers 121 would communicate with the part of chamber 21 which would thus remain at module level before 3.
  • the number and sizing modules 103 would be adapted to the desired power for the boiler.
  • This variant has not been illustrated but it is easily deduced from a comparison between the embodiment described in reference to FIG. 8 and the embodiment described with reference to Figures 1 to 7.
