Abstract (en)
A combustion membrane (14, 14') for a gas burner (2) comprises a layer made of perforated metal sheet (23), in which perforation holes (24) of an individual perforated metal sheet (25) of the layer of perforated sheet (23) have a ratio (D/S) between an equivalent diameter (D) of the hole (24) and the thickness (S) of the individual sheet (25) which is greater than or equal to 1 (D/S ≥ 1),wherein the layer made of perforated metal sheet (23) comprises a plurality of said individual perforated metal sheets (25) overlapping in a pile of sheets and with said holes (24) overlapping and aligned to form channels (26) for the passage of the combustible gas (13) through the pile of sheets, wherein said channels (26) have a ratio (D1/S1) between an equivalent diameter (D1) of the channel (26) and the thickness (S1) of the pile of sheets which is less than 0.7 (D1/S1 < 0.7).
