<p>This atmospheric gas burner which produces convergent roots' flames is suitable in particular for open burners tops; it consists of a venturi pipe (3) producing the air/gas mixture and feeding in sequence a circular duct (6), an annular duct (7a) and at last the, housing (8a) and (8b) which has been created with the flame diverter on the annular duct (7). This flame diverter, which is the subject of the innovation, consists of a single piece of known material and it is equipped with an internal cylindrical shaped notch fitted to receive the air/gas mixture coming from the annular duct (7) and to covey it to the convergent semicircle shaped slots (11), producing the main flames' crown, and to the holes (9) the pilot flames (Fp). These flames are fed by the secondary air that entirely surrounds the convergent semicircle shaped slots (11) and the pilot flame (Fp). <IMAGE></p> |
