Definitions

  • the invention relates to a closed combustion system according to the Preamble of claim 1.
  • a self-excited combustion oscillation is caused by a resonance oscillation i.e. a standing wave in the gas / air side and exhaust side flow paths evoked.
  • Standing waves cause fixed alternating waves in the flow paths Pressure bellies or knots. Positive pressure bellies alternate along the current thread, (Pressure node) and negative pressure belly.
  • the standing wave leads to a considerable noise and unsanitary combustion.
  • the aim of the invention is to avoid these disadvantages and a combustion system to propose the type mentioned above, in which the formation of a self-excited Combustion vibration is largely prevented.
  • the proposed measures ensure that positive and negative Pressure belly can be connected to each other via the short-circuit opening and therefore can compensate, causing the standing wave to collapse.
  • the features of claim 2 have the advantage that a very extensive Compensation of the pressure bellies can take place and only a relatively low flow resistance is given over the annular gap.
  • the features of claim 3 give the advantage of a constructive aspect very simple solution.
  • annular burner flange 9 is in a gas-air mixture feed line 11 arranged.
  • a flow element 2 is in this burner flange 9 held, the embodiment shown being a funnel tube, that the inflow cross section into a mixture chamber 8 of a cylindrical surface burner 12 narrowed with its mouth 14.
  • the mixture chamber 8 is delimited by a cylindrical distribution plate 5, which is in the area its outer surface is provided with outflow openings and by means of a dense bottom 7 is tightly sealed at the end.
  • the distribution plate 5 with play from Outflow openings provided burner jacket 4 surrounded by a Bottom 6 is tightly closed.
  • the flange-like edge 13 of the Flow element 2 spacers arranged distributed over their circumference in the form of Embossments 3 with which the flow element 2 abuts the burner flange 9.
  • the flow element 2 is in position with a welding spot 10 Burner flange 9 secured.
  • This short-circuit opening 1 enables a connection between the inflow and the outflow side of the flow element 2, the could also be designed as a throttle.
