Definitions

  • the invention relates to a head for ventilated multi-layered chimneys according to the preamble of claim 1.
  • Such chimney heads are from DE-OS 34 38 696 in connection with an approval notice from the Institute for Building Technology, Berlin, dated December 23, 1985, approval no . Z-7.1.162 known.
  • house chimneys are chimneys that are included in a building structure.
  • the construction of prefabricated components has become common, which in turn can be individual shell-forming elements or whole modules that can only be vertically stacked, which in turn can be composed of prefabricated shell elements.
  • Widespread - and particularly considered within the scope of the invention - is an at least three-shell structure, namely from at least one flue gas duct carrying flue gas, in particular made of fireclay or steel, a surrounding thermal insulation layer, in particular mineral fiber including glass fiber, and a thermal insulation layer surrounding the thermal insulation layer , a supporting function, usually made of lightweight concrete.
  • the dew point within the house chimney can be undershot, which in turn can lead to moisture and sooting phenomena and thus to a reduction in the thermal insulation effect.
  • These adverse phenomena are exacerbated by the aggressive constituents of the flue gases carried by water vapor, in particular SO2 and SO3 and various hydrocarbons. Condensation, for example, leads to the precipitation of sulfurous acid or sulfuric acid.
  • the arrangement of inward to open channels in the corner areas is also rectangular, in particular square, on the outside and round-shaped cladding stones on the inside in accordance with the two lower ouadrants of FIG. 5 of DE-OS 32 11 536.
  • the rear ventilation duct formation is provided between the flue gas duct and the insulation layer.
  • the invention is concerned with the removal of the ventilation air or other ventilation gas in the chimney head.
  • the rear ventilation air or the like is discharged below the cover plate, either into the flue gas duct, for example through a perforated expansion joint collar according to DE-OS 33 02 889 or through a Opening in the casing directly to the outside (Fig. 4 of DE-OS 32 11 536).
  • the ventilation gas and the flue gas are combined with one another before they pass through the cover plate. Because of the same flow direction of both types of gas, this is relatively uncritical and nevertheless not always desirable.
  • a smoke exhaust pipe is finally known, in which a flue gas pipe protrudes axially from an outer heat-insulating jacket made of fireclay tube, an annular space being provided between the flue gas pipe and the outer jacket, through which chimney-like air from for cooling the flue gas pipe can flow from the bottom up.
  • the face of the outer jacket is connected by a steep conical apron to both flanks of a gable roof, through the apex of which the smoke exhaust pipe is led.
  • an attachment is provided which, on the one hand, forms a distribution head for horizontal discharge of the flue gas and, on the other hand, carries a housing which, together with the conical apron, forms obliquely downward outlet openings for the cooling convection air.
  • a connection of the housing to the apron is not provided.
  • the opening in the cover plate, through which the flue gas pipe passes is instead formed with an oversize.
  • the e.g. The main body of the flue gas pipe consisting of shaped parts made of chamotte ends below the cover plate. Through the opening in the cover plate upwards, the flue gas pipe is supplemented by a metal extension pipe which is inserted into the main body.
  • the annular gap between the outer surface of the flue gas pipe and the edge of the opening forms the passage opening for the rear ventilation air vertically upwards.
  • the passage opening is provided with a ring-shaped upper cover which is carried by the flue gas pipe.
  • a cylinder of an expansion joint sheet lining the opening in the cover plate and projecting upwards over this takes over the function of an outlet housing which conducts the emerging rear ventilation air at the front cylinder opening and the rear ventilation air underneath the upper cover along with the ring skirt has unrestricted lateral passage to the outside.
  • the object of the invention is to create a chimney head which can be produced at least largely in a prefabricated construction - as a whole prefabricated or built up from individual parts - in which the passage opening (s) of the rear ventilation air in the cover plate against rain and Influences of dirt are or are protected as well as possible and, if necessary, good decoupling of flue gas and ventilation gas is also ensured.
  • the rear ventilation air or another rear ventilation gas is also passed through an outlet housing which provides at least one outlet opening for the rear ventilation gas which is independent of the (respective) passage opening in the cover plate.
  • the invention now also provides to extend the flue gas duct of the house chimney, namely a fireclay pipe, as the flue gas pipe through the cover plate upwards in a very unconventional manner and thus to avoid all the problems associated with the provision of a separate extension pipe for the cross-sectional constriction of the Flue gas pipe are caused by the extension pipe, by the insertion joint and by the metallic material of the extension pipe.
  • the cover housing can be attached to the cover plate according to claim 3 or can only sit loosely on it according to claim 2. In the latter case, there is a positive engagement with the cover plate.
  • the invention relates specifically to the case in which the rear ventilation air is guided radially outside the heat insulation layer.
  • they can be guided radially inwards in the region of the chimney head by axially resetting the upper end of the thermal insulation layer and thereby forming a connecting chamber between the respective upper ends of the rear ventilation duct or the rear ventilation ducts. This makes it possible.
  • the cover collar is preferably attached to the flue pipe by means of a cement connection. This is of particular importance since a flue gas duct constructed from fireclay, for example from individual fireclay tubes cemented together, is led upwards through the cover plate. In this case, in particular, the cover collar is expediently formed from fireclay. In general, it is also preferred that the outlet housing and preferably also the cover collar consist of fireclay. Technical reasons for this are the corrosion resistance against aggressive components of the flue gas carried by the ventilation gas as well as good sound insulation properties of the chamotte in comparison with other materials in question, such as corrosion-protected metal, e.g. Steel, sheet.
  • At least the predominant outlet cross section for the ventilation gas can be oriented horizontally in the chimney head according to the invention.
  • the figure shows a vertical radial section through a first embodiment of an upper end of a three-shell ventilated house chimney with a chimney head.
  • This design of house chimneys, has a three-shell design with a cylindrical flue gas duct 2, which consists of individual fireclay pipes cemented together, a heat insulation layer 4 made of glass or other mineral wool surrounding the flue gas duct 2, and a supporting covering 6 made of lightweight concrete.
  • the thermal barrier layer 4 forms a cylinder shell.
  • the inner surface of the casing is cylindrical, while its outer surface is preferably rectangular or square. With 8 the axis of the flue gas duct is designated.
  • a rear ventilation duct 10 (or a plurality of rear ventilation channels distributed over the circumference, which for the sake of simplicity are designated by the same reference number 10) upwards, which carries ventilation air or another ventilation gas in the sense of the arrows shown.
  • the rear ventilation duct 10 or several of these rear ventilation ducts is or are arranged radially outside the thermal insulation layer 4. Specifically, this figure relates to the cases in which the respective rear ventilation duct 10 is arranged between the thermal insulation layer 4 and the casing 6 or within the latter. A gas permeability of the thermal insulation layer is required. The main flow takes place in the respective rear ventilation duct 10, while the thermal insulation layer is acted upon by the rear ventilation air for the removal of water vapor and other vaporous aggressive components.
  • the house chimney also includes a wall 12 surrounding the cladding 6.
  • the cover plate 16 also rests on the wall 12, depending on the structural requirements, also mortared or cemented on or provided with its own ventilation ducts for the wall.
  • the cover plate 16 has a cylindrical vertical opening 20 which surrounds a cylindrical flue gas pipe 22 which projects upwards through the cover plate 18.
  • This flue gas pipe 22 is an integral part of the flue gas duct 2, which as such projects freely upwards through the cover plate. Specifically, this is a flue gas pipe 22 made of fireclay, preferably as a pipe or possibly cemented together from firebrick pipe elements. in principle, unattenuated cross-section in relation to the other flue gas duct 2, if one of conicities customary in construction u. the like.
  • the respective rear ventilation duct 10 is connected to the passage opening 28 via a connecting chamber 31 which is formed at the upper end of the thermal insulation layer 4 which is axially set back from the casing 6.
  • This connecting chamber 31 serves to bridge the thermal insulation layer 4 from the respective rear ventilation duct 10 arranged radially on the outside thereof to the passage opening lying radially further inside.
  • the connecting chamber 31 can be used for this. for example, gas emerging from the thermal insulation layer 4 at the top and together with the rear ventilation gas coming directly from the respective ventilation duct 10 to the passage opening 28.
  • the maximum distance of the edge of the opening 20 from the axis 8 of the flue gas pipe 22 is smaller than the minimum absland of the rear ventilation duct or ducts 10 from the axis 8 of the flue gas pipe 22 and thus the respective rear ventilation ducts 10 assume a greater horizontal extent than the passage opening 28.
  • an outlet housing 30 which forms at least one outlet opening which is independent of the passage opening 28 and through which the rear ventilation air or other rear ventilation gas is guided to the free atmosphere.
  • the axial length compensation takes place in the area of an expansion joint 32 between the flue gas pipe 22 and the outlet housing 30.
  • the outlet housing 30 is then not fastened to the flue gas pipe 22 or to the flue gas duct 2 which is extended upwards, but only connected to the cover plate 16 stationary.
  • a loose seat is sufficient, preferably with positive centering; in many cases, however, the outlet housing will be fastened to the cover plate 16, which is not shown separately in the drawing and can be done by customary known means.
  • the figure shows that one can completely dispense with horizontal separate outlet openings - or in part in a manner not shown - by simply designing a cylinder jacket 48 which extends the through opening 28 without a noticeable radial oversize as the outlet housing and which extends from the cover collar 44 to form a stream of the rear ventilation gas axially deflecting labyrinth seal is overlapped.
  • the interior of the cylinder jacket 48 also forms the expansion joint 32 between the outlet housing 30 and the flue gas pipe 22.
  • the disk-shaped circumferential cover collar 44 here advantageously has an inverted pot shape with a cup wall or an annular skirt 50, which forms the outer jacket surface of the cylinder jacket forming the outlet housing 30 48 overlaps and thus forms a vertically downward annular gap as an outlet opening.
  • the pot base 51 can optionally also be designed in a funnel-shaped manner, but in the embodiment shown, the pot base 51 is oriented horizontally.
  • the passage opening 28 in the cover plate 16 is protected against the ingress of rain and dirt.
  • the upper edge of the passage opening 28 is first formed with a circumferential edge web, so that water and dirt can be collected radially outside of it and, if necessary, drained off.
  • a collecting channel 54 of a water drainage system can adjoin the edge web, which channel is formed by a radially outwardly running drainage channel and a further inclined surface of the cover plate 16 with a radially outward slope.
  • the water drainage system can be designed such that condensate dripping on the lateral lateral surface of the outlet housing is collected by the water drainage system.
  • the entire roof is expediently designed as an inverted funnel, if appropriate also only reaching to a drip edge or provided with such.
  • outlet housing 30 or the outer edge of the rain and dirt-repellent collar has a cylindrical outer contour which adapts to the likewise cylindrical outer contour of the cylindrical flue gas pipe 22.
  • the outer contour of the entire outlet housing 30 is then appropriately square or, in general, elongated rectangular. It goes without saying that other geometric modifications are also possible depending on the expediency.
  • the entire chimney head can be prefabricated in the factory, just like the axial reset of the thermal insulation layer. This applies in particular to the outlet housing 30 with associated Rain and dirt-repellent elements, the cover plate 16 and the cover collar 44.
