Definitions
- the invention relates to a burner for gaseous Fuels comprising one from at least one plate-shaped part existing burner body with a Flow direction of the gas-air mixture upstream Inflow surface, a downstream outflow surface and between them passages, of at least a number of those in the inflow surface lying mouths of the passage channels the respective Distances to an upstream thereof perforated reference plane are unequal.
- a burner for gaseous Fuels comprising one from at least one plate-shaped part existing burner body with a Flow direction of the gas-air mixture upstream Inflow surface, a downstream outflow surface and between them passages, of at least a number of those in the inflow surface lying mouths of the passage channels the respective Distances to an upstream thereof perforated reference plane are unequal.
- Such burners are known per se from EP-A-0 602 831.
- the burner body mostly made of a heat-resistant ceramic material.
- a number of the torch bodies shown in EP-A-0 602 831 is simply curved.
- a periodic Function is defined here like a curve with a Repeatedly occurring function value and course, transverse to Gas mixture flow direction seen.
- the distance variation preferably fulfills in one dimension of the burner body transverse to the gas mixture flow direction at least one period of the periodic function, the is preferably a sine function. Another variation according to several functions is possible.
- a burner body is used a flat inflow surface, and is the Reference plane is a perforated plate that is in one dimension transverse to the gas mixture flow direction runs.
- the reference plane is a substantially flat, perforated Plate is while the inflow surface of the burner body in a dimension transverse to the flow direction of the flammable gas-air mixture is undulating.
- This flat plate can be the conventional distribution plate.
- the request for protection extends to one in the Claims 7 and 8 defined gas burners.
- the figures show a design in which the burner body is substantially plate-shaped; however is also one Configuration possible in which the torch body in the cut is circular or C-shaped, or another Configuration.
- Fig. 1 shows in longitudinal section and schematically a part a plate-shaped burner body 2 with a Inflow surface 4, and an outflow surface 6 with between them channels 8, the one in the flow direction 10 combustible gas-air mixture that has an upstream the burner body 2 arranged distributor plate 12 with Perforations 14 flow, run. Form during operation there are flames 16 on the side of the outflow surface 6.
- a such a structure with burner body 2 and distributor plate 10 is known per se and has those mentioned above disadvantages described.
- a perforated plate 18 corrugated in a single direction is arranged upstream of the inflow surface 4, which forms the reference plane mentioned in the claims.
- the distance of its mouth 8'a, indicated by d 1 is different from the distance d 2 between the mouth 8'b of this surface.
- the corrugations in the plate follow a sine function; its zero line is indicated by 20, the period by P and the peak-to-peak amplitude by A. Values for these sizes chosen for practical training are given at the end of this description.
- Fig. 2 shows in perspective how the invention Practical measures can be implemented in a simple manner can.
- the burner body 2 is in a housing 22 arranged; the outflow surface of the burner body 2 forms the surface of this housing.
- the bottom of the housing is covered by the plate 12 formed, and a corrugated, perforated metal plate 24, which forms the reference plane 18 in Fig. 1 is between Burner body 2 and distributor plate 12 arranged.
- This corrugated plate 24 can also be as obvious will form the bottom of the case, the plate 12 is then omitted.
- FIG. 3 shows how the proposed according to the invention Measures without extensive modifications in one already existing construction can be realized. More in particular, Fig. 3 shows a detail of one from the applicant Manufactured and placed on the market from Type "Ecomline".
- the combustible gas-air mixture fed through the feed pipe 30 and flows then in the direction of arrow 32 to the burner unit 34, with, seen in the direction of flow 32, one after the other Distribution plate 36 (comparable to distribution plate 12 in FIG. 2) and the perforated ceramic burner body 38 (comparable to the burner body 6 in FIG. 2, or 1).
- corrugated and perforated plate 40 without significant change in construction between the Distributor plate 36 and the burner body 38 are arranged become; practice has shown that this in itself is very simple measure to a surprising and substantial Acceptance of that produced by the burner during operation Noise leads. Easy attachment of the burner 34 on the boiler structure 42 with the insertion of the Sealing profiles 44 make the burner 34 easily accessible.
- the degree of perforation of the distribution plate 36 was 4% and that of the perforated plate was 40.50% with a substantially regular perforation pattern.
- the outflow surface 52 of the burner body 50 is a flat plane
- the inflow surface 54 is designed to be corrugated in a direction transverse to the inflow direction of the combustible gas-air mixture, which also has the effect here that the respective distances of the mouths of the adjacent through-channels 58 which run between the inflow surface 54 and the outflow surface 52 are different.
- the distance is given for channel 58a with d 3 and for channel 58b with d 4 .
- the perforated reference plane 60 is formed here by the conventional distributor plate.
