Burner assembly

The invention relates to a burner assembly (1) comprising a combustion chamber (2), a plurality of mixing ducts (3) leading into the combustion chamber (2), in which mixing ducts, during intended operation, introduced combustion air (4) and introduced fuel (5) are mixed, wherein the mixing ducts (3) are formed by mixing tubes (6) which extend axially through an annular space (7) that is defined between a tubular outer wall (8), a tubular inner wall (9) arranged radially at a distance from the outer wall (8), a ring-shaped end plate (10) arranged upstream and a ring-shaped end plate (11) arranged downstream, wherein the end plates (10, 11) are provided with through-openings (12), which accommodate and/or extend the mixing tubes (6), and said end plates have, both radially inside and radially outside, a circumferential edge (13, 14) extending in the direction of the annular space (7), wherein axial bores (15) are provided in the edge (13, 14) of the ring-shaped end plate (11) arranged downstream, which axial bo
