Definitions
- the invention relates to a closed combustion system according to the Preamble of claim 1.
- a self-excited combustion vibration is caused by a resonant vibration, i. a standing wave in the gas / air side and exhaust side flow paths caused.
- Standing waves cause stationary alternating in the flow paths Bellows or knots.
- the aim of the invention is to avoid the disadvantages of the prior art and a Propose combustion system of the type mentioned, in which the training a self-excited combustion vibration is largely prevented.
- the proposed measures ensure that positive and negative Pressure belly are connected to each other via the short-circuit opening and therefore can compensate, causing the standing wave to collapse.
- annular burner flange 9 in a gas-air mixture supply line 11 arranged.
- this burner flange 9 is a flow element. 2 held, wherein it is a funnel tube in the illustrated embodiment, that is the inflow cross section into a mixture space 8 of a cylindrical surface burner 12 narrowed with its mouth 14.
- the mixture space 8 is limited by a cylindrical distribution plate 5, which in the area its lateral surface is provided with outflow openings and by means of a dense bottom. 7 is closed tightly at the end.
- the distribution plate 5 with game from with Outlet openings provided burner jacket 4 surrounded, the front side by a Floor 6 is tightly closed.
- the flange-like edge 13 of the Flow element 2 distributed over the circumference arranged spacers in the form of Defeats 3, with which the flow element 2 rests against the burner flange 9.
- the flow element 2 with a weld point 10 in its position in Burner flange 9 secured.
- This short-circuit opening 1 allows a connection between inflow and the outflow side of the flow element 2, the could also be designed as a throttle.
