摘要：A Food cooking oven includes a steam-generation boiler, a gas burner, a fan for generating a forced air flow through and injecting gas into the burner, an outer conduit branching out from the burner and adapted to convey the flue gases through the boiler. The gas burner includes a first inner, preferably cylindrically shaped body and a second outer body that is in direct communication with the outer conduit and accommodates the first inner body so as to form a pre-mixing region in the hollow gap created therebetween. The outer surface of the first inner body is provided with a plurality of first apertures, which are distributed all over the outer surface, and the surface of the second outer body is provided with a plurality of respective second apertures, which are preferably provided to cover just a single, delimited portion of the respective outer surface and are in direct communication with the outer conduit.
