Abstract
A combustion membrane (14) for a gas burner (2) comprises a fabric or mesh (21) of interlaced metal threads (22), having two opposite interlacing surfaces (19, 20) which form a combustion surface (19) and an inner surface (20) of the fabric/mesh (21), respectively, wherein the metal threads (22) are formed by twisted metal fibers (22) to form a yarn and: the individual metal fibers (22) are shorter than the yarn (22) formed therefrom, and free ends (22″) of the metal fibers (22) protrude divergently from the yarn (22) along its longitudinal extension and make the yarn (22) hairy, and the metal thread (22) is a yarn (22) of mass per length in the range from 0.8 g/m to 1.4 g/m.
Claims13
A combustion membrane (14) for a gas burner (2), said combustion membrane (14) having an inner side (18) to which a combustible gas (13) is conveyed and an outer side (17) on which combustion of the combustible gas (13) occurs after the combustion gas it has crossed through the combustion membrane (14), said combustion membrane (14) comprising a fabric or mesh (21) of interlaced metal threads (22) having two opposite interlacing surfaces (19, 20), which respectively form a combustion surface (19) exposed on the outer side (17) and an inner surface (20) facing towards the inner side (18), wherein the metal threads (22) are formed by metal fibers (22′) twisted to form a yarn, and:
- the metal fibers (22′) are shorter than the yarn (22) formed therefrom, and free ends (22″) of the metal fibers (22) protrude divergently from the yarn (22) along the longitudinal extension of the yarn and make the yarn (22) hairy, and
- the metal thread (22) has a mass per length in the range from 0.8 g/m to 1.4 g/m.
