Abstract

A burner module according to the invention comprises at least three or four or five or six or seven or eight functional walls which delimit at least one first functional space and form a module body, wherein the module body has at least three or four or five or six or six or seven gas passage openings and at least two of these gas passage openings are connected to one another communicatively via the first functional space, and wherein at least one nozzle device having a fuel gas opening is formed in an upper wall of the burner module, which fuel gas opening is connected communicatively to the first functional space via a gas channel. The burner module is produced in an additive manner.

First claim

The invention claimed is:

1. A burner module for a modular burner, comprising:
at least three functional walls which delimit at least one first functional space and form a module body,
wherein the module body has at least three gas passage openings formed in the functional walls, and at least two of these gas passage openings are connected to one another communicatively via the at least one first functional space, and
wherein at least one nozzle device having a fuel gas opening is formed in an upper wall of the burner module, which fuel gas opening is connected communicatively to the first functional space via a gas channel, and wherein the burner module is manufactured in an additive manner.

2. The burner module according to claim 1 , wherein the module body has at least three functional passage openings, and at least two of these functional passage openings are connected to one another communicatively via a second functional space, wherein the second functional space is spatially separated from the first functional space.

3. The burner module according to claim 2 , wherein the second functional space is connected communicatively via a functional channel to a further opening of the nozzle device formed in the upper wall in order to form an air shower.

4. The burner module according to claim 1 , wherein the module body has at least three further passage openings,
wherein at least two of these further passage openings are connected to one another via the first functional space or the second functional space in order to form a mixing chamber in the first functional space or the second functional space, or
wherein at least two of these further passage openings are connected to one another communicatively via a further functional space, wherein the further functional space is spatially separated from the first and the second functional space and is optionally connected communicatively via a channel to a further opening of the nozzle device formed in the upper wall.

5. The burner module according to claim 1 , wherein the gas passage openings are formed completely or in regions in the functional walls, and wherein, when the gas passage openings are formed in regions in the functional walls, they are then formed by two adjacent functional walls.

6. The burner module according to claim 1 , wherein the burner module is triangular, quadrilateral, pentagonal, hexagonal, heptagonal, octagonal, or polygonal or approximately round when viewed from above.

7. A modular burner comprising a plurality of burner modules according to claim 1 , which are connected to one another in a region of their functional walls to form a burner module array, wherein the burner module array is manufactured additively in one piece, and wherein burner modules arranged peripherally have one or more closed sidewalls.

8. The modular burner according to claim 7 , wherein at least one feed device is provided for feeding one or more media.

9. A method for the additive manufacture of a three-dimensional burner module or a modular burner, comprising the following steps: providing a starting material, melting the starting material using a heat source to form a component layer, repeating the above steps, wherein a burner module according to claim 1 is formed by the plurality of component layers.

10. The method according to claim 9 , wherein different starting materials are used in different layers and/or in different regions in one or in multiple steps.

11. The burner module according to claim 2 , wherein the functional passage openings are formed completely or in regions in the functional walls, and wherein when the functional passage openings are formed in regions in the functional walls, they are then formed by two adjacent functional walls.

12. The burner module according to claim 2 , wherein the gas passage openings and/or the functional passage openings are formed completely or in regions in the functional walls, and wherein, when the gas passage openings and/or the functional passage openings are formed in regions in the functional walls, they are then formed by two adjacent functional walls.

13. The method according to claim 9 , wherein different starting materials are used in different layers and/or in the nozzle region of the burner module in one or in multiple steps.
