The reduction of noise burners with a greater speed of combustion gas is in combustion chambers body of which, consisting of a plane-parallel arrangement of rings, which are embedded together with the adjacent mixer and outlet part, in a steel shell, is achieved by the fact that between individual rings as well as between the mixer and chamber body on one side, and between the outlet part and chamber body on the other side, a silencing insert is installed, made of a fireproof fibre material, provided that the chamber body is separated from the shell by an insulating-silencing layer.<IMAGE>
