- FIGS. 6a to 6e show diagrammatic views from above of a burner 11 with, for example, two burner zones 34, 35, which have different arrangements and geometries. It is understood that instead of two burner zones, it is also possible to provide a plurality of burner zones which have an analogous structure.
- FIG. 6a shows an end view of the burner head 23 according to FIG. 2 with a round combustion zone 51, whereby FIG. 6a deviates in that the at least one ignition electrode 31 and / or monitoring electrode 32 is not centered but off-center in the tissue membrane 49 of the first burner zone 34 is arranged.

- the first and second burner zones 34, 35 have equal areas, which are separated by the contact line 64, in each of which a combustion zone 51 with a semicircle for the first and second burner zones 34, 35 is formed.
- the first burner zone 34 of the combustion zone 51 may comprise a circular arc segment and the second burner zone 35 occupy the remaining area
- FIG. 6c shows an alternative geometric configuration of the combustion zone 51 to FIG. 6b, in that the first and second burner zones 34, 35 are square, but with the same area division.
- a rectangular arrangement may also be provided.
- a division with respect to a square combustion zone 51 can also take place via a diagonal contact line 64.
- FIG. 6 e shows a further alternative embodiment, which comprises a flat-rectangular combustion zone 51 of the first and second burner zones 34, 35, which comprise a common contact line 64.
- Such an embodiment is preferably provided in so-called ingot burners whose length comprises a multiple of the width.

The individual flames 59 are thus aligned in the flow direction within the combustion zone 51.
- the housings 24 of the burner heads 23 for the first and second burner zones 34, 35 may, for example, abut each other at a contact point 65 or have only a small spacing, and the at least one ignition electrode 31 and / or monitor electrode 32 may be positioned in a gusset resulting therefrom that a central or eccentric arrangement of the ignition electrode 31 and / or monitoring electrode 32 in the first burner zone 34 is not required. However, this can also be chosen. This makes it possible to skip the flame matrix 52 out of the first burner zone 34 into the second burner zone 35 when the burner 13 is connected to the second burner zone 35.
- the ignition electrode 31 and monitoring electrode 32 can be assigned to the first burner zone 34 and a further monitoring electrode 32 can be assigned to the second burner zone 35.
