Definitions

  • the invention relates to a blower-assisted, over-stoichiometric premixing gas burner with a partition arranged between a combustion chamber and a mixture chamber, which has passage openings for the mixture, and with a throttle arranged in the mixture chamber upstream of the partition.
  • Such a gas burner is known from EP-PS 0 092 838.
  • a burner plate is provided there as a partition.
  • a piece of curved sheet metal is arranged upstream of this plate in the mixture channel in order to suppress burner vibrations by throttling action.
  • the mere provision of this sheet is not yet fully satisfactory in terms of its effect.
  • the invention is therefore based on the object of further developing a gas burner of the type mentioned in such a way that the throttle can fully meet its purpose.
  • the throttle for vibrationally decoupling the combustion chamber from the mixture chamber defines at least one throttle opening with a total cross section which is 2 to 10%, preferably 2 to 5%, of the total cross section Through openings of the partition is.
  • This rule represents a sustainable remedial measure in that the throttle causes a high pressure loss of the gas-air mixture conveyed with excess pressure and thereby causes the vibration separation of the mixture chamber from the combustion chamber to an increased extent.
  • the features according to the invention which have since been successfully tested, bring about reproducible suppression of burner vibrations practically over the entire air ratio and power range with any burner design. Whistling and howling tones completely disappear. There is also a significant improvement in the mixture distribution, so that corresponding distribution internals can be dispensed with. It is particularly advantageous that the pressure of conventional fans is sufficient for the gas burner to function properly and that after the fuel gas has been mixed with the air, enough pressure remains to be able to cope with the pressure loss caused by the throttling without problems.
  • a particularly advantageous embodiment for use in gas boilers with a cylindrical combustion chamber is that the partition and the throttle are designed as cylindrical components which are held at one end by a mixer-side transition piece and are connected at their other end to a burner cover.
  • One of the cylindrical components is firmly connected both to the transition piece and to the burner cover, while the other cylindrical component engages with at least one end in a longitudinally displaceable manner in a guide of the transition piece or the burner cover.
  • the partition is to be provided with anti-kickback devices on both sides.
  • fire-resistant soft seals can advantageously be inserted into the guides.
  • the partition wall represents the cylindrical component which is firmly connected both to the transition piece and to the burner cap.
  • a further improvement in the mixture distribution is achieved if obstacles are opposed to the high mixture outlet impulses, so that the mixture jets do not strike the through openings of the partition wall directly.
  • a baffle element opposite the throttle opening can advantageously be arranged as a separate component between the throttle and the partition.
  • the baffle element has passage openings which are arranged offset with respect to the throttle openings of the throttle.
  • the passage openings of the impact element have a total cross section of at least 30%, preferably 40 to 70% of the total cross section of the passage openings of the partition.
  • At least one cylindrical component is advantageously provided as the impact element.
  • baffle element which is designed as a cylindrical component, is held at one end by the transition piece and is connected at its other end to the burner cap, the baffle element having at least one end being longitudinally displaceable in a guide for the transition piece or the burner cap intervenes. In this way, damage caused by thermal stresses can also be avoided with this component.
  • burner jacket itself can act as a baffle element by leaving unperforated sections on the burner jacket.
  • a particularly simple and inexpensive construction of the gas burner is obtained if a cylindrical burner jacket, preferably 0.5 to 1.3 mm thick, is provided to form the dividing wall, which connects to the mixer with a rotationally symmetrical transition piece, at its end by a burner cover is closed and is provided with the passage openings, which have a hydraulic diameter of 0.8 to 1.5 mm, in a hexagonal arrangement, the throttle being a cylinder arranged within the burner jacket between the transition piece and the burner cover and having the throttle openings in rows of circles .
  • numeral arrows illustrate the flow of an over-stoichiometric gas-air mixture, which enters the cylinder 1 with overpressure in the sense of the drawing, whose throttle openings 2 pass through, which are arranged in rows 3 above one another, and finally essentially radially exits through openings 4 of a cylindrical burner jacket 5 and burns there uniformly, as is partially shown in FIGS. 2, 4 and 6 with arrow heads.
  • the cylinder 1 and the burner jacket 5 are closed at the top by a common burner cover 6.
  • the passage openings 8 have a total cross section of at least 30%, preferably 40 to 70% of the total cross section of the passage openings 4, the partition 5.
  • the impact element consists of a plurality of sheet metal cylinders 7a, which each cover a circular row 3 of the throttle openings 2 in a ring and are fastened to the cylinder 1 by spacers 9.
  • FIGS. 5 and 6 are constructed similarly to the above-described embodiments.
  • the throttling cylinder 1 is, however, provided at a distance of only 5 mm from the burner jacket 5 this time.
  • the fuel gas flows through the gas nozzle 10 into a chamber 11 of a mixer 12 designed as a hole mixer.
  • the combustion air is added to the chamber 11 with the aid of a blower (not shown).
  • the mixture flows through bores 12a (only one shown) and a conically widening transition piece 13 into the cylinder 1, which is arranged within the burner jacket 5 in the sense of FIG. 5.
  • the thickness of the burner jacket 5 is between 0.5 and 2 mm.
  • the burner jacket 5 has the passage openings 4 in a hexagonal arrangement, the hydraulic diameter of which is 0.8 to 1.5 mm. The hexagonal arrangement of these openings results in a high degree of perforation and thus a low exit surface load with a high total surface load.
  • Figure 8 differs from Figure 7 only in that the plate cylinder 7 serves as a baffle element and by the type of mounting of the three cylindrical elements 1, 5 and 7.
  • the burner cap 6 and the transition piece 13 have guides 14 into which the burner jacket 5, the plate cylinder 7 and the cylinder 1 engage.
  • the guides are shown on the burner cover side without the cylindrical elements 1 and 7 for better illustration.
  • the burner jacket 5 is bolted to the burner cover 6 and the transition piece 13 in a non-return manner.
  • the cylinder 1 and the sheet metal cylinder 7 are held in the guides 14 so as to be longitudinally displaceable.
  • the burners shown in the drawings can be either hanging, depending on the intended use. H. with the burner cap facing down, as well as standing, d. H. with the burner cap facing upwards.
  • the hanging installation method is particularly advantageous for gas boilers with flue gas condensation, since the condensate can drip off without affecting the burner.
