Abstract (en)

In a burner assembly for combustion of an air-hydrogen mixture on a burner surface (235), comprising a burning unit (120) with an air-hydrogen mixture flow-through section (230) that comprises a plurality of slotted orifices (250) for flow-through of air-hydrogen mixture, wherein the air-hydrogen mixture flow-through section (230) embodies the burner surface (235) and comprises a first length (232) and a first width (234) that is smaller than the first length (232), and wherein each slotted orifice (252, 255, 257) of the plurality of slotted orifices (250) comprises a second length (259) and a second width (258) that is smaller than the second length (259), the second width (258) amounts at most to 0.6 mm, and the second length (259) is at least essentially arranged in parallel to the first width (234).
