Definitions

  • the invention relates to a discharge structure for closed gas appliances.
  • Such discharge structures form the main component of a roof terminal or wall terminal for, for instance, heating boilers and comprise a line for the supply of combustion air and a line for the exhaust of combustion gasses.
  • the discharge structure then further comprises a supply means for combustion air, such as a supply hood, forming the connection between the outside air and the supply line for combustion air, and a flow-promoting exhaust means for combustion gasses, such as a draught hood, forming the connection between the combustion gas exhaust line and the outside air.
  • the exhaust means is situated at a greater distance from the space in which the gas appliance is located than the supply means, that is to say, in a vertical arrangement of the discharge structure, above the supply means.
  • Such a discharge structure is also referred to as a wall or roof terminal structure.
  • the inner end is considered as the end which has to be connected to the combustion air supply and the combustion gas exhaust of the gas appliance itself, whether through the medium of a manifold or not, with which manifold or branch pipe the combustion gas exhaust line and the combustion air supply line in the discharge structure, situated concentrically relative to each other, are transformed into parallel lines.
  • a discharge structure as described in the preamble of claim 1 is known from EP-A-0.491.444.
  • an improved discharge structure for closed gas appliances is provided, as described in claim 1
  • the venting passage forms a direct connection for combustion air between the main passage, formed by the air supply means, and the outside air. Too high a pressure built-up inside the air supply means, in particular the air supply hood, which could form a disturbance for the burner or, as a consequence of air streams caused thereby, for the efficiency of the appliance due to losses during standstill, are hereby controlled.
  • combustion air supply means is embodied as a supply hood, reaching on its inner end over the outer end of the casing and defining an entrance of the main passage therewith, then preferably the venting passage is provided in or at the outer end of the hood, in particular in the shape of one or more holes.
  • US-A-3.361.051 discloses a discharge structure having an air supply hood which has a main passage having radially extending portions bounded by projections spaced in the circumferential direction.
  • the combustion gas exhaust means can be formed by an outer end of the inner pipe itself, but is preferably formed by a combustion gas exhaust hood, especially in vertical discharge structures.
  • the discharge structure 1 of figure 1 comprises an inner pipe 20 for discharge of combustion gasses in the direction B, towards the outside, an outer pipe 30, for the supply of combustion air in the direction A, from the outside to a boiler (not shown), an air supply hood 40, a combustion gas exhaust hood 50, an insulating sleeve 60, a retaining ring 70 and a clamping ring 80.
  • the discharge structure can either connect directly with its bottom end to the connecting pieces of the boiler, or to concentric line components connected thereto, or can be connected thereto via a so-called manifold and parallel line components. If the circumstances render it possible, it could be considered to include the parts 70 and 80 into the manifold.
  • the inner pipe 20 passes on its outer end, in this case its upper end, via an annular shoulder 22 into a portion having a larger diameter 21. What is especially important here is the shoulder 22, of which the function will be further discussed below.
  • the outer pipe 30 consists of two parts 30a and 30b.
  • the pipe part 30a herein has a length, corresponding to the regulations concerned.
  • the outer pipe 30b can simply be adapted in length to the situation in situ.
  • pipe part 30a is provided with a storm collar 39', and also with a retaining ring 39'' situated therein, and active in radial direction for keeping the pipe part 30b in position relative to pipe part 30a.
  • the storm collar 39' furthermore serves to accommodate the upper end of a so-called adhering plate (i.e. flat roof adaptor for bitumen) 90, for sealing the passage through the roof 10.
  • the adhering plate 90 sealingly connects to the roof covering (not shown).
  • the pipe part 30a is provided with a number of radial partitions 31 distributed in circumferential direction, which partitions are provided on their outer upper end with a recess 32. Below these small partitions 31, immediately adjacent thereto, are situated radially projecting spacing fingers 34 which are also evenly distributed over the circumference. Furthermore, below these, there are located two roundgoing pressure increasing rings 35 and 36, and below these there are located roundgoing fastening ribs 37 and 38.
  • the air supply hood 40 is provided with an annular supply opening for ambient air and starts, considered from the bottom upwards, with an edge 42, a first essentially cylindrical portion 41, which passes via a first radial step into a second, essentially cylindrical portion 43 having a reduced diameter, which portion 43 passes via a tapering portion 45 into a second, essentially radial step, which finally ends in a third essentially cylindrical portion 46.
  • a raised roundgoing collar 47 is situated radially outside the portion 46, while between both parts 46 and 47, in the second radial step, a number of air passages 48 are present, evenly distributed in circumferential direction, which air passages form a short circuit between the passage from the outside to the annular line and the ambient air so as to vent the surplus of air.
  • the gas exhaust hood 50 comprises, considered from the bottom upwards, an annular bottom portion 55, provided on its radial inner side with a raised ring 54, situated more outwardly with a depending ring or series of projections 56 and even more outwardly with a downwardly extending ring 57.
  • a roundgoing, slightly tapering screen 58 or wind shield band is situated, connected to the bottom by means of raised portions 51' and to the roundgoing lid support 53 via legs 51''. In this way, draught openings 59' are left clear below the screen 58 and exhaust holes 59'' are left clear above the screen 58.
  • the lid 52 is situated on top of the exhaust hood, by which means it is prevented that rains comes in or that objects fall into the exhaust hood and that otherwise the functioning of the exhaust hood is improved by deflecting fall wind.
  • the collar 47, the annular bottom portion 55 and the ring 57 form a labyrinth-shaped screen for the air openings 48, so that rain can be prevented from entering and a gust of wind can also not impair the air pressure surplus-reducing action of the openings 48.
  • An insulating sleeve 60 is placed around the inner pipe 20, which insulating sleeve extends from the lower end of the outer pipe 30 up to the gas exhaust hood.
  • Assembling the discharge structure 1 is done as follows.
  • the pipe 20 is kept upside down, with the widened portion 21 pointing downwards. If necessary, this widened portion 21 can be placed on a raising having a fitting, comparable diameter.
  • the gas exhaust hood 50 is slid on the inner end or lower end, now the upper end, of the inner pipe, until the ring 54 touches the shoulder 22.
  • the exhaust hood is hereby detained against further direction and moreover centered relative to the inner pipe.
  • the air supply hood 40 is made to slide downwards over the inner pipe, until the axial annular portion 46 touches the annular bottom 55 of the exhaust hood 50.
  • the portion 46 is herein retained in radial direction by the ring or series of cams 56.
  • the diameter of the portion 46 of the supply hood 40 is chosen such, that radial space is present for the insulating sleeve.
  • the next step is that the insulating sleeve is slid over the inner pipe until what is then the bottom extremity, also touches the annular bottom 55 of the exhaust hood, and is centered at that location by the portion 46 of the supply hood 40.
  • the outer pipe 30 is lowered over the inner pipe 20 and the insulating sleeve 60, until the upper edge of the recesses 32 of the small partitions 31 touches the inner surface of the area of the wall of the supply hood 40 near the transition from the cylindrical portion 43 and the first step thereof (fig.
  • the retaining ring 70 When the outer pipe has been installed, the retaining ring 70 is installed, which retaining ring is provided with two rings 71 and 73, placed concentrically relative to each other and being connected to each other by means of small radial partitions 72. These small radial partitions between them leave clear sufficient flow openings for the combustion air supplied to a manifold, not shown in more detail, which is connected to the inner end of the annular space in an almost sealing manner, and which connects on its other side to the air supply and the gas exhaust of the gas appliance.
  • the inner ring 73 On its upper end, seen in figure 1, the inner ring 73 is provided with a locating edge 74, with which the insulating sleeve 60 is positioned relative to the inner pipe 20.
  • the ring 71 is formed such that it connects smoothly onto the outer pipe 30b.
  • a ring 80 closely fitting onto the inner pipe 20, is slid on until it abuts retaining ring 70 and then secured by means of tipped screws 81 on the inner pipe 20.
  • the exhaust hood 50, the supply hood 40, the outer pipe 30 and the insulating sleeve 60 are retained between the shoulder 22 and the clamping ring 80.
  • the discharge structure is turned over and the lid 52 is secured onto the exhaust hood 50. This can for instance be done by means of screws or by means of a snap connection.
  • the various components of the discharge structure according to the invention can be manufactured from aluminium, highgrade or not, stainless steel, steel, galvanized according to the Sendzimir process. Due to the chosen method of composition, however, most components can be made of a synthetic material. This applies to the gas exhaust hood (PBT), the air supply hood, which is not subjected to high temperatures and can for instance be made from PVC, the part of the outer pipe 30a projecting above the roof, and the part of the outer pipe 30b below the roof, which can both also be manufactured from synthetic material, such as PVC or PE, the retaining ring and the clamping ring.
  • PBT gas exhaust hood
  • the air supply hood which is not subjected to high temperatures and can for instance be made from PVC
  • the part of the outer pipe 30a projecting above the roof and the part of the outer pipe 30b below the roof, which can both also be manufactured from synthetic material, such as PVC or PE, the retaining ring and the clamping ring.
  • FIG 2 shows an alternative discharge structure 101, built up substantially from an inner pipe 120, a casing 130 an air supply hood 140, a combustion gas exhaust hood 150.
  • the discharge structure 101 is essentially similar to the discharge structure shown in figure 1.
  • the combustion gas exhaust hood 150 is however more tapering than the combustion gas exhaust hood 50.
  • a calm flow pulse is obtained, while maintaining the guiding and wind screening function.
  • the combustion gas exhaust hood 150, of which the lid 152 is removable can be nested, so that during transportation from for instance the manufacturer to the next link in the supply chain, less space will be required.
  • the chosen shape also offers advantages for the manufacturing process, because of its self-releasing shape.
  • FIG. 2A Another special feature of the discharge structure of figure 2 is shown in figure 2A.
  • the combustion gas exhaust hood is made of another material than the air supply hood 140, for instance when the former is made of injection aluminium and the latter is made of a synthetic material, it can be desirable to install a temperature buffer in the shape of a ring 200 which is concentrical to the centre line of the discharge structure and is made from, for instance, PBT synthetic, which has a high temperature resistance.
  • the ring 200 can also be applied as a optional component on the previously mentioned short circuit between the passage from the outside to the annular line and the ambient air to vent the surplus of air, if desired.
  • the ring 200 is provided with depending projections 202 which are spaced from each other in circumferential direction, and between them leave clear radial passages 203, through which a surplus of air can flow from within the air supply hood towards the outside, around the downwardly extending ring 157.
