In a combustion chamber for a gas turbine, noise absorption is achieved over a wide frequency range with simultaneous cooling of the arrangement and low space requirement by the inner wall being formed, at least in a partial region of the inner walls by at least two perforated plates arranged essentially parallel to one another, and by the distances between the perforated plates and the geometrical dimensions of the openings being selected in such a way that a plurality of mutually connected Helmholtz resonators is formed and that, in addition, further e...
1. A combustion chamber for a gas turbine, said combustion chamber comprising inner walls inside of which hot combustion gases of a combustion zone are cooled by cooling air, said cooling air being introduced into said combustion zone through cooling air ducts outside the inner walls, said cooling air ducts being formed by an outer wall of the combustion chamber and the inner walls, wherein, at least in a partial region of the inner walls, the inner walls are formed from at least two perforated plates arranged substantially parallel to one another, where...
