2:

• A burner system for a cooking device, comprising a fuel supply and a first burner surface for the combustion of fuel that is provided downstream of the fuel supply, wherein the burner system comprises a second burner surface for afterburning that is separate from the first burner surface and is provided downstream from the first burner surface.

3:

• The burner system according to claim 2, wherein at least one of the first burner surface and the second burner surface are provided with a catalyst material.

4:

• The burner system according to claim 2, wherein an ignition electrode is provided on the first burner surface for igniting the fuel.

5:

• The burner system according to claim 2, wherein a first air supply is provided upstream of the first burner surface.

6:

• the burner system according to claim 2, wherein a second air supply is provided upstream of the second burner surface in such a way that it can supply air to the second burner surface.

7:

• The burner system according to claim 6, wherein an exhaust chamber is configured between the first burner surface and the second burner surface, wherein the second air supply opens into the exhaust chamber.

8:

• The burner system according to claim 2, wherein several first burner surfaces are provided which are covered by the second burner surface.

9:

• The burner system according to claim 2, wherein the first burner surface is part of a radial burner or part of a surface burner.

10:

• The burner system according to claim 2, wherein at least one of the first burner surface and the second burner surface are each configured on a burner body, such as at least one of a metal-fiber mat, a mesh, a knitted material, a porous ceramic and a perforated sheet.

11:

• The burner system according to claim 10, wherein the burner system comprises a cylindrical housing with two end faces and the first burner body is also configured cylindrically within the housing, wherein a space is configured between the first burner body and the housing.

12:

• The burner system according to claim 11, wherein the fuel supply opens into the space.

13:

• The burner system according to claim 11, wherein the housing is closed at the downstream end face by the second burner surface.

14:

• The burner system according to claim 11, wherein at least one of the first air supply is provided upstream of the first burner surface and the second air supply is provided upstream of the second burner surface in such a way that it can supply air to the second burner surface, and wherein the second air supply is provided centrally on the upstream end face of the housing.

15:

• The burner system according to claim 2, wherein the burner system comprises a distribution plate.

16:

• The burner system according to claim 15, wherein the second burner surface constitutes the distribution plate.

17-30. (canceled)

31:

• A method for operating a burner system for a cooking device, wherein fuel is combusted on a first burner surface of the burner system and the exhaust gases generated during combustion are afterburned on a second burner surface of the burner system.

32:

• The method according to claim 31, wherein air is supplied to the second burner surface for afterburning.

33:

• The method according to claim 31, wherein the amount of heat usable for cooking is controlled by the amount of air supplied for afterburning.

34:

• The method according to claim 31, wherein a catalyst material provided on at least one of the first burner surface and the second burner surface enables complete combustion at lower temperatures than would be the case without the catalyst material.
