Definitions
- the invention is based on a gas burner of the type of the main claim.
- a This type of gas burner (PCT / DE 95/01663) is the Burner plate for the purpose of forming contact surfaces, that extend over the apex areas of the flame roots extend to the side areas, structured so that the edges of the combustion chamber on certain ribs their entire length compared to the combustion chamber side Edges of adjacent ribs are protruding. It is preferably provided that between two higher ribs two lower ribs side by side are arranged. In this version, the higher take Ribs also have a higher temperature than the other ribs to different extents of the ribs or Slats and therefore possibly undesirable Can cause stress in the burner plate.
- the arrangement according to the invention with the features of The main claim has the advantage that the ribs are only slightly different in shape and largely uniform expansion of the ribs when the burner is in operation is achieved. Due to the vertical edges on the raised The flames become additional edges of the ribs stabilized.
- Flame stabilization is particularly good if the raised edge areas of adjacent ribs offset are arranged to each other.
- the burner plate is structured in pairs opposite contact surfaces at the desired distance for the flame roots, if for the ribs and the raised edge areas have a uniform pitch provided and this is such that at Relocation of the raised edge areas of adjacent ribs the width of a border area the specified number of Channels, preferably three, between two themselves opposite contact surfaces results.
- the contact surface pairs are staggered, but follow each other without a gap in the longitudinal direction.
- Burner plate can also be provided with individual fins the one end face a directly beginning there, in shortened the length of the raised edge area and on the other End face an equally long, not raised edge area have, which means a tool for a further rib or Slat design is not required.
- FIG. 1 shows a reduced scale the inner body of a water heater in longitudinal section, figure 2 in approximately natural size a top view of the Gas burner of the water heater according to Figure 1 and the figures 3 to 5 three individual elements of the gas burner according to FIG. 2.
- the water heater has a gas burner in a housing 10 12, which is a fuel-air mixture atmospheric or below Blower pressure is supplied in the direction of arrow A. over the gas burner 12 is a combustion chamber 14 and a heat exchanger 16 arranged by a pipe system 18 is penetrated, which leads to the water to be heated.
- the pipe system 18 is connected via a line 20 to a second one Pipe system 22 connected to the gas burner 12 to the Cooling is integrated.
- About the gas burner 12 is on Housing 10 an ignition device 24 for starting the Attached water heater.
- the gas burner 12 has a burner plate 26 (FIG. 2) which is formed from individual ribs or fins 28, 30, 32 which are in good heat-conducting contact with the pipe system 22 and are connected by this to form a rigid structural unit. Between the ribs 28, 30, 32 channels 34 are formed for the passage of the fuel-air mixture, which reacts after the gas burner 12 is ignited in the region of the combustion chamber-side mouths of the channels 34 with the formation of flames.
- the burner plate 26 is structured in the manner described in more detail below such that the majority of the flames of adjacent ribs touch over a defined area which extends beyond the apex region of their roots. As a result, the flames are cooled to such an extent that even higher surface loads on the gas burner are possible, without resulting in impermissibly high No x values.
- each rib 28, 30, 32 is on Longitudinal edge on the combustion chamber side with raised edge regions 36 provided that removed at the same pitch t are arranged from each other and also the same width b have a third of the pitch t.
- the rib 30 differs from the rib 28 in that their raised edge areas 36 in the longitudinal direction of the rib the dimension b is offset from the edge regions 36 of the rib 28 are arranged.
- the edge regions 36 are at the rib 32 by the dimension b compared to the edge regions 36 on the rib 30 staggered.
- the ribs 30, 32 each have one Front a shortened raised edge area 38 which to adjacent unshortened edge region 36 a distance c which is the difference between the pitch t and the Width b of the edge regions 36 corresponds. On the other On the end face, the ribs 30, 32 are not raised Edge area 40, the length of which is that of edge area 38 corresponds.
- the ribs 28, 30, 32 are in the shown sequence repetitive arranged. As shown in FIG. 2, this results in each case between two opposite, for the sake of clarity black border areas 36, 36 and 38, 38 three Channels 34.
- the edge areas 36, 38 are heat-dissipating guide surfaces 42 are formed for the flames, whose roots on the non-raised edge areas 40, 44 of the Sit on ribs.
- the edge areas 36, 38 are staggered, however in the longitudinal direction of the ribs with no visible Gap between each other so that there is a good one Heat dissipation at approximately the same thermal All ribs are loaded.
- the raised edge areas 36, 38 become the flames additionally stabilized.
- the ribs 30 and 32 can with the same tool because they have the same shape are and can be installed mirror-symmetrically.
