摘要
The invention relates to gas-fired boilers. In order to attenuate the frequencies emitted on the inside of the hermetically closed box (1) surrounding the burner/exchanger assembly, a perforated plate with the shape of a basket (4) is provided, the perforations of which are regular and constant, and, on the outside of this basket, in the space provided between it and the box, a plastic foam mattress is positioned, which is capable of eliminating the residual noise created by the perturbations in the gaseous flows. Application in hermetically closed condensing boilers. IMAGE
