Abstract

An air-cooled gas burner (1) comprises: a plurality of ramp-like elements (2), each of which includes a first and a second intake duct (21, 22), having a respective inlet (21A, 22A) and a respective outlet (21B, 22B), wherein the plurality of ramp-like elements (2) are disposed in succession along a transverse direction (T); a manifold (3), configured to feed the gas to the inlets of the first and second intake ducts (21, 22), wherein the first and second intake ducts (21, 22) are configured to suck the gas and primary air into their respective inlets (21A, 22A) by the Venturi effect; for each ramp-like elements (2), a respective diffuser (4), defining a plurality of holes (40) from which a flame is generated by combustion of the gas coming from the first and the second intake duct (21, 22).
