Definitions

  • the invention relates to a boiler in link construction Burn liquid or gaseous fuels consisting of a horizontally oriented combustion chamber with adjoining vertically oriented secondary heating surfaces, whereby the links are individually connected to flow and return collectors and the links forming the secondary heating surfaces made of cast aluminum with a cast water system are.
  • Such boilers are known, for example, from DE-A-43 02 479 namely there as part of a special embodiment, the such a special assignment of the combustion chamber and secondary heating surfaces shows.
  • all individual links are parallel arranged side by side to the combustion chamber longitudinal axis, i.e., such Single links are only suitable for this special construction and can not be used for a construction at the links are arranged transversely to the longitudinal axis of the combustion chamber, which is also known from DE-A-43 02 479.
  • the shape of the links in boilers with horizontal oriented combustion chamber and vertically oriented secondary heating surfaces or hot gas trains are feasible, but relative inconvenient and complex and thus the water flow within the limbs.
  • the invention is based, while maintaining the task Advantages of boilers of the type mentioned in this regard to improve and shape the limbs of design measures untouched for the formation of the combustion chamber remain and form a link like the others Links regarding their water supply also, separately to the fore and aft Return collector can be connected.
  • connection of the combustion chamber there is another advantageous embodiment in that the combustion chamber side
  • the shape of the link on the gas side corresponds to that of the subsequent links, but on the combustion chamber side of increases in heat transfer area kept clear and provided with combustion chamber connection surfaces is.
  • the link furthest from the combustion chamber i.e. the end link must of course as in the boiler according to DE-A-43 02 479 a closed Form wall that also in the area of the hot gas flue with heat transfer area enlargements like the other links is also provided.
  • the boiler design according to the invention an extremely clear and easy to put together Modular system, in which you can also in the The combustion chamber length easily to the respective one to adapt combustion-technical requirements or if necessary easy to exchange.
  • the boiler according to the invention is based on the graphic representation of an embodiment explained in more detail.
  • the sectional boiler consists in a known manner of a horizontally oriented combustion chamber 1 with adjoining, vertically oriented secondary heating surfaces 2, the links G being connected individually to flow and return manifolds 3, 4 and the secondary heating elements 2 forming members G 1 made of light metal casting are formed with a cast water system WS.
  • the water supply system WS made of steel pipes requires no further explanation, which is also known for its integration in cast aluminum members.
  • the Combustion chamber 1 forming member G in the form of a housing Sheet steel with a water-bearing and connected to the collector 3, 4 Double jacket 6 formed and on the combustion chamber side Link 7 is flanged, the and its transverse to the longitudinal axis of the combustion chamber 8 arranged followers 9 except for the end link 10 an essentially corresponding to the combustion chamber cross section Q.
  • the combustion chamber 1 whose water-cooled wall covers this, one or multi-part shell and in thermal contact with this 13 made of light metal.
  • the shell 13 uses an Al cylinder with a wall thickness of only 2 mm, for example for example by pre-cooling something in relation to its nominal size, with the this was shrunk, inserted into the combustion chamber and is heat-conducting to the wall 12 when heated of the combustion chamber.
  • an Al cylinder is on the one hand corrosion protection on the gas side
  • no boiler water gets to the Al cylinder, since the steel wall is in between , i.e. there are the same advantages for the combustion chamber before, as on the links G by the cast in there Water pipe system made of steel pipes.
  • the combustion chamber-side link 7 corresponds in shape to the gas side the followers 9, but is on the combustion chamber side of heat transfer area enlargements kept clear and with combustion chamber connection surfaces 15 provided.
  • connection flanges 18 are cast on to all links G 1 . Except for the connections 19 to the collectors 3, 4, the entire boiler does not require any liquid cable seals, since each link G, including the combustion chamber, forms a self-contained water supply unit.
  • the water pipe systems WS for the individual members G 1 are advantageously and preferably formed according to FIG. 3 from molded, thin sheet steel shells 24, into which, as shown, the front and return-side steel tubes 25 are integrated or welded. It is also possible, however, to form the strand 26 comprising the opening 11 'entirely from tubular steel.
