Definitions
- the invention relates to an atmospheric gas burner according to the preamble of claim 1.
- injector burner atmospheric gas burners are well known and have found both for hot water and heating water heating a wide distribution.
- the goal in the further development of this gas burner without water cooling is to further reduce the pollutant content of the exhaust gases, in particular the NO x content.
- From EP 769 656 is an atmospheric gas burner with several, arranged side by side in parallel Burner elements with a mixing body and a Burner plate with mixture outlet openings known.
- the Burner plate is curved in a substantially semi-cylindrical shape executed and as attachable unit with the mixing body connected.
- the mixing body has two mixing tubes, the each narrowing the flow cross-section, delta-shaped Have constrictions in the sheet metal elements formed mixing tubes are formed. In the sheet metal elements There are also openings in which cooling tubes for cooling the burner elements are guided.
- a burner with a burner element is known that two have juxtaposed injectors with two mutually inclined mixing tubes.
- the object of the invention is to provide an atmospheric gas burner without water cooling, which has a high combustion stability and a low NO x emission at a modulation range greater than 1: 2.5.
- the thermal stress of the material of the burner element is to be reduced.
- the atmospheric gas burner according to the invention with the characterizing features of claim 1 has the advantage that a primary air number of 0.5 to 1.0 is achieved.
- the measures according to the invention make it possible to achieve a reduction of the NO x exhaust gas values to 20 mg / kWh without additional water cooling. Due to the optimized spacing of the burner elements and the gap formed therebetween, a sufficient secondary air supply and one of EP 0679839 A1 as well as complete combustion is ensured over the entire modulation range of the gas burner.
- the flow conditions of the secondary air also realize cooling of the burner elements, in particular in the region of the burner plate or burner zone. At the same time thereby the thermal stress of the material of the burner element is lower.
- FIG. 1 shows a view of the broad side of a Burner element
- Figure 2 is a view of the narrow side of Burner element in Figure 1
- Figure 3 is a sectional view through the burner element in Figure 1 along the line III-III
- Figure 4 is a partial section through two adjacent Burner elements
- Figure 5 is a view of the broad side of a Burner element according to a second embodiment
- FIG. 6 shows a view of the narrow side of the burner element in FIG Figure 5
- Figure 7 is a sectional view through the Burner element in Figure 5 along the line VII-VII.
- FIG. 1 shows a burner element 10 of a not closer illustrated atmospheric gas burner.
- the atmospheric gas burner consists of a number of parallel adjacent burner elements 10th About the arrangement of a corresponding number of Burner elements 10, the burner power can be arbitrary increase.
- the burner element 10 has one of two bowl-shaped Sheet metal halves 11, 12 housing 14 formed as well on the combustion chamber side designed as a ridge strip Burner plate 16 with mixture outlet openings 18, wherein in Embodiment according to Figures 1, 2 and 3, the burner plate 16 is curved.
- Each burner element 10 has two mixing tubes 20 (Injectors) each having an air inlet opening 21, a flow channel section 23 and a diffuser section 25 on.
- the flow channel section 23 points at one point 35 on the narrowest cross-section of the mixing tube 20.
- the Air inlet openings 21 serve for introducing Primary air, each air inlet opening 21 is a gas nozzle 27 is assigned. About the gas nozzle 27, the fuel gas in the mixing tube 20 is injected.
- the flow channel section expands 23 slightly conical towards the diffuser section 25.
- To the Flow channel section 23 closes in Flow direction of the fuel gas-air mixture of Diffuser section 25 on.
- the diffuser sections 25 each widen symmetrically to one through the Center line of the mixing tubes 18 extending level 28 in Direction of the broad side of the burner element 10th continuously in the form of a parabolic extension 29.
- the extension 29 of a mixing tube unites with the extension 29 of the adjacent mixing tube at one Position 31 so that both parabolic extensions 29 open into a common distribution chamber 30.
- the Distribution chamber 30 is the burner plate 16 and the Preceded mixture outlet openings 18 and extends essentially on the extent of the burner plate 16th
- the diffuser sections 25 each have according to Figure 3 a the cross section with respect to the narrow side of the Burner element 10 constricting constriction 32, the Essentially symmetrical to one through the midline extending plane 33 is formed.
- Left and right of the constriction 29 form two diffuser channels 40, whose flow cross sections are larger than that Flow cross-section of the constriction 29 at any Job. This results in a uniform mixture distribution in the distribution chamber 30 over the entire extent of Mixture outlet openings 18 achieved.
- the surface of the mixture outlet openings 18 and the flow conditions of the fuel gas-air mixture in the two mixing tubes 20 are matched to one another such that the heat load on the mixture outlet openings 18 of the burner plate 16 ⁇ 300 W / cm 2 .
- the mixture outlet openings 18 and the mixing tubes 20 were dimensioned accordingly, wherein the surface of the mixture outlet openings 18 corresponds to about 3-5 times the total cross-sectional area of the mixing tubes 20 at the narrowest point 35. Due to these geometric conditions influence on the flow velocity of the fuel gas-air mixture is taken in the mixing tubes 20, wherein a higher flow velocity of the fuel gas-air mixture means a higher surface load or heat load.
- the width B is approximately 1.5-2 times the height H. The design also allows a significantly lower overall height H compared to fully premixing gas burners
- a section of two arranged side by side Burner elements 10 shows Figure 4. Between the Burner elements 10 is a gap for the supply of Secondary air formed with a width X, wherein the Width X is about 1/2 to 1/5 of the depth Y of the burner plate 16 is. Because of this sizing is over the entire modulation range of the atmospheric gas burner achieved a sufficient secondary air supply, which a complete combustion is guaranteed. About the Secondary air supply also finds a cooling of the Burner element 10, in particular in the field of Burner plate 16 instead.
- FIG. 10 Another embodiment of a burner element 10 show the figures 5, 6 and 7, wherein the same elements with are denoted by the same reference numerals.
- the Burner plate 16 formed flat.
- this Embodiment according to Figure 7 is the cross section in Area of extension 29 narrowing section of the Narrow side of the fuel assembly 10 considered as a narrowing channel 36 is formed, which is symmetrical to the passing through the centerline of the mixing tubes 20 level 33 is formed.
- the narrowing channel 36 has a delta-shaped Widening 38 on, symmetrical to that through the Midline extending level 28 is.
- this Embodiment forms left and right of narrowing channel 36 two diffuser channels 40, whose Flow cross sections is greater than that Flow cross-section of the narrowing channel 36 at a any place.
