Definitions

  • the invention relates to a discharge structure for an outlet structure of a gas discharge apparatus, such as a heating system, in particular a heating boiler.
  • the invention further relates to a so-called outlet structure for a closed gas appliance, comprising an air supply structure and a discharge structure according to the invention.
  • the screening means comprise a cover plate located downstream or above the outlet of the gas discharge pipe, which cover plate is arranged substantially perpendicular to the centre line of the discharge pipe.
  • a suchlike cover plate is there to prevent a (fall) wind blowing directly into the gas discharge pipe and thus obstructing the discharge.
  • the cover plate prevents birds from entering and too much rain coming in as well. Condensate takes place against the lower side of the cover plate. It will be possible for condensate drops to collect on the lower side and drip down. To aid this the lower side is often formed having a central lowest portion, to where the drops can flow along the lower side.
  • An outlet structure with a provision for collecting and returning condensate to inside ,parts of the outlet structure as described in the preamble of claim 1 is known from the Dutch patent application 94.00659.
  • the discharge structure in that outlet structure is provided with a collecting dish, which has a circumference such that condensate drops from parts located therabove, especially the cover plate, are collected and which connects at its lower end in a water drop discharging fashion to the combustion gas discharge pipe.
  • the intention is, among other things, to collect the water drops that have thus been led into the gas discharge pipe at the bottom of the discharge gas pipe, so that from there they are conveyed to the sewer system, for example.
  • the invention now aims at providing a discharge structure or an outlet structure of the kind described in the opening paragraph, with which an improved and thus safer removal and collection of condensate is possible, so that ice formation is virtually ruled out.
  • the invention provides a discharge structure as described in claim 1.
  • the condensate guiding means comprise a number of circumferentially arranged bars or strips that surround the outlet and a downstream area thereof in radially outward direction and extend with a component in the pipe direction and that are in discharging liquid communication with the collecting means.
  • the condensate guiding means ensure interception, adhesion and guiding of the drops to the collecting means, irrespective of the shape of the cover plate, also if the discharge structure is inclined. As a result of adhesion forces the condensate drops will remain on the bars and will flow down along them to the collecting means, across through the gas flow.
  • the bars can make even a lowest portion on the cover plate superfluous. So the plate can be formed in several different ways, for instance even with a concave lower side.
  • the bars or strips moreover provide for guidance of the discharge gasses and also for wind interruption, so that in the case of hard wind drops are, to a large extent, prevented from being swept along and then landing at places outside the collecting means where ice formation then occurs.
  • the bars or strips are substantially vertically oriented.
  • the bars connect at their downstream end to a ring or dish, which may be integral with the cover plate so that they, too, form an integral part with the latter.
  • the said ring or dish is provided with radially inward notches or recesses between the bars connections.
  • the connection of a bar with the ring, dish or plate will almost certainly, even if in an extremely slanting position, will form a lowest point for the plate, so that drops of condensate formed on the plate will flow off via the bars to the collecting means.
  • the cover plate or ring can be provided on the lower side with discharge guiding formations, such as ridges.
  • the screening means can, in a manner known per se, comprise a wind shelter strip surrounding the outlet at a radial distance, the downstream edge of which is located - in a vertical projection - within the outer circumference of the collecting means.
  • a suchlike wind shelter strip can have the shape of a cylindrical band. Condensate that forms on the inside thereof and subsequently runs off will be collected by the collecting means and discharged via the aformentioned passing means to the gas discharge pipe.
  • the bars or strips are radially outwardly spaced from the wind shelter strip.In this way a double discharge of condensate is provided.
  • the run-off of the drops along the bars is not interrupted by horizontal parts such as a wind shelter strip.
  • a two-stage wind interruption is provided.
  • a narrower (less high) wind shelter strip can be selected, whereby the condensate forming surface thereof will be reduced and the structure height can be restricted.
  • FIG 1 an air supply hood 2, which is provided on its lower side with a main air supply to an air supply pipe 5 located therebelow for a closed gas appliance, also located therebelow, and is provided on the upper end with a surrounding wind shelter ring 3, which screens a secondary air pressure relief opening.
  • a gas discharge pipe 4 which also comes from the gas appliance and is concentrically located within the air supply pipe 5, reaches above the air supply hood 2.
  • the dish 6 is further provided with a discharge pipe stub 21, which is coaxial with the ring 13 and has the same diameter.
  • the pipe stub 21 is formed integrally with connecting webs 24 regularly spaced from each other in circumferential direction (fig. 4), which in this case are themselves formed integrally with the rest of the dish 6.
  • the discharge pipe stub 21, the webs 24 and the collection surface 11 determine radial passages 26 for condensed water to the inside of the discharge pipe 4, which passages are aligned with that surface 11.
  • a discharge hood 7 is shown (vide also fig. 3), which is formed in one part and comprises as it were a horizontal and a vertical screen structure, the vertical screen structure being formed by vertical bars 18, which are separated from each other by vertical passages 19 and are connected to each other at the top by means of plate 8, which substantially serves as fall wind screen, and are connected to each other at the bottom by means of a surrounding flange 17, which is provided on the outside with a sharp clamping edge 23.
  • the horizontal screen structure is formed by a wind shelter strip 20, which is at a radially inward distance from the bars 18 and located about and at a distance from the upper end of the discharge pipe stub 21 and the area located directly above there.
  • the wind shelter strip 20 and the discharge pipe stub 21 define between them an axial annular space 10 (fig. 4).
  • the wind shelter strip 20 is held in position by means of a number of vertical connecting webs 22 spaced from each other in circumferential direction, which are in this case formed integrally with the wind shelter strip 20 and the plate 8. In between the webs 22 there are gas discharge openings 25.
  • the gas discharge pipe 4 is provided at its top end with an edge 9 with an enlarged diameter, in which the positioning ring 13 of dish 6 is received with a press fit.
  • the inner surface of the positioning ring 13 will therefore be in line with the inner surface of the gas discharge pipe 4 (fig. 4).
  • the other parts of the outlet structure 1 according to the invention can also be positioned from above.
  • hood 7 is positioned on top of the collecting dish 6. Fixing the hood 7 to the dish 6 takes place with the help of a press fit or by clamping (fig. 4), to which end the surrounding flange 17 with the downwardly inclined and outwardly extending clamping edge 23 engages in the inner surface of the upright edge 12 of collecting dish 6.
  • the outlet structure is thus assembled and takes on the appearance of figure 2 or 4. Upon assembly no screws are needed, nor is riveting necessary.
  • the division in the various parts has the added advantage that the parts can be manufactured from the material most suited to their function, taking among other things the temperature load into consideration. It is important that the collecting dish 6 is made of condensate and temperature resistant material. Attention should be paid that the material used for the hood 7 is resistant to high temperatures, as well as being resistant to condensate and UV proof. Materials filled with glass can be dispensed with, whereby the hygroscopic effects linked to that will be absent.
  • the plate 8 will also be inclined, whereby the condensate drops will move outward along the lower surface to the lowest point (G), from where they would drop down outside the collecting dish 6 to then contribute to undesirable formation of ice on lower parts of the roof or of the outlet structure.
  • the hood 7 is provided on the outer circumference with vertical webs or bars 18. Condensate which runs down along the plate 8 in outward direction will arrive at the surface of a bar 18 via the lower surface of the plate 8, be deflected downward (H) under the influence of adhesion and gravitational force and then run off in the direction D, to finally fall from the lower end 14 thereof on the collection surface 11 and to be further drained off (F) in the manner described above.
  • Transferring the condensate drops to the bars 18 is promoted further by the curved course or the extension with a radially outward component of the bars 18 near the connection to the plate 8, whereby in the vicinity of the connecting area between a bar 18 and the plate 8 a lowest point of the top end of the hood 7 is almost always formed. A usually used cover plate with a lowered centre is then no longer needed.
