Definitions

  • the invention relates to a boiler.
  • a boiler is known, the having a tumble burner.
  • the fall burner is on one Heat exchanger assembly directed to a tube bundle composed of tubes and the exhaust of the burner heads down.
  • the heat exchanger assembly is of Water flows around, which absorbs the heat from the pipes.
  • From US 4 380 215 A is also a boiler known working with a tumble burner.
  • the fall burner is directed into a heating pipe by a water jacket is surrounded.
  • the fall burner is in its upper Isolated area to overheat the water in the upper Area of the water jacket to avoid.
  • baffles are arranged, which the flow of the fuel gas so that the gases under the water jacket be brought into a collection chamber to the water jacket to heat from below.
  • the combustion chamber dips into the water jacket from above and has a lateral, heat-insulating lining.
  • Of the Burner is arranged on the side of the boiler and penetrates with his burner tube the water jacket and the Side wall of the combustion chamber.
  • the burner blows the flue gas directly into the heating tube into it, so that an energetically unfavorable deflection the flue gas is eliminated. Also, the entire heat input takes place in the water jacket over the heating tube. So it needs not the heating of a thermal surrounding the combustion chamber Insulation. The water jacket becomes unique penetrated by the heating tube. It therefore eliminates the lateral Breakthrough of the known boiler, which served the Burner to connect to the combustion chamber. A considerable one constructive simplification is the result.
  • the flue gas Leitein agencies are, as well as in the known Construction, cup-shaped and borders with their upper, radially outwardly projecting edge of the Heating tube, wherein it is nozzle-like in its side wall Have passage openings. It is special advantageous in that the uppermost, the combustion chamber limiting Leitun deeper than the following Leitein algorithms is trained. He has accordingly a higher one Number of nozzle openings. This takes into account the fact that the flue gases at the exit from the flame their maximum Own volume.
  • the heating tube is designed as a one-piece jacket Stainless steel formed.
  • the Boiler a condensate collecting tray inclined to the horizontal on, which forms an intermediate bottom of the heating tube and merges into a lateral condensate drain pipe. The condensate is thus from the heating tube directly into the outlet pipe initiated.
  • the flue gas Leitein accounts can, as well as in the known Construction, carried by a central pole be, where it is particularly advantageous that the Rod supported on the condensate collecting tray. It deals So it is a statically very cheap construction.
  • the Flue gas duct above the condensate collecting tray laterally from the heating tube.
  • the total pollutants are thus from the Heating pipe out directly from the boiler, without to apply additional internal spaces of the boiler. This is a very environmentally friendly and beneficial extremely simple construction.
  • Fig. 1 in a schematic representation of an axial vertical section by a boiler according to the invention.
  • the boiler has a housing 1, which has a Water jacket 2 contains.
  • the water jacket 2 is connected to a supply line 3 and connected to a return line 4.
  • the water jacket 2 by a heating tube. 5 interspersed.
  • the heating tube 5 is up over the water jacket 2 led out and forms with its upper section a combustion chamber for a tumble burner 6. This is on the upper end of the heating tube 5 is arranged.
  • the fall burner 6 thus blows the hot flue gases directly into the heating tube 5 into it.
  • the heating tube 5 includes a plurality of flue gas guiding inserts 7, which are cup-shaped and with their adjoin the upper, radially protruding edge of the heating tube. In their side wall they have nozzle-shaped openings 8 on.
  • the flue gas is progressing from top to bottom into the Interior of the Leitein accounts 7 steered and leaves them the nozzle-like passage openings 8, wherein flue gas jets form on the inner surface of the water-cooled Heating tube 5 impinge.
  • the flue gas cools progressively so strong that the auskondensierbaren Components of the flue gas with appropriate heat dissipation liquefy.
  • the uppermost flue gas Leitrus 7 is formed higher as the subsequent lead inserts and points accordingly also a larger number of nozzle-like passages 8 on. This takes into account the fact that the flue gas at the outlet of the tumble burner 6 has its maximum volume.
  • the condensate runs on the inner wall of the stainless steel manufactured, one-piece heating tube 5 down and there meets an inclined condensate collection tray 9, the merges into a condensate drain neck 10. Above the Condensate collecting tray 9 branches a lateral flue gas line 11 from the heating tube 5 from. All pollutants are so from the heating pipe directly from the housing 1 of the boiler led out, without further interior of the boiler apply.
  • the heating tube 5 is supported on a bottom plate 12 of the Boiler off. It also directs the weight of the flue gas Leitein accounts 7 in the bottom plate 12 a.
  • the flue gas guiding inserts 7 are in fact attached to a central rod 13, which is supported on the condensate collection tray 9.
  • the boiler can with a majority be fitted by heating pipes, these each a condensate drain pipe and a flue gas pipe exhibit.
  • Cheaper however, it is alogiestufung by heating pipes of different diameters and accordingly to achieve adapted flue gas Leitein algorithms.
  • the Flue gas guide inserts can be designed so that the condensate Partly flows into the Leitein algorithms and there again evaporated. The pollutants then form a crust the pot bottoms, which are easily removed in the course of maintenance can be.
  • In the illustrated embodiment is a exact vertical alignment of water jacket and heating tube selected. Angular deviations are equally possible, where however, the orientation is essentially vertical should stay.
