Abstract (en)

Atmospheric gas burner of longitudinal type with a radiating element which generates lateral conduits for the stabilization of the flame in which, a curved length ( 21 ), which is made in the centre of the metallic rectangular plate that is forming the radiating element ( 2 ), is tightly fixed to the tubular and cylindrical length ( 11 ) which is laterally provided with two raws of primary holes ( 14 ) and two raws of secondary holes ( 15 ) and it is positioned in the portion which is comprised between these latter secondary holes. Two curved portions are realized laterally to the curved length ( 21 ) and are bent outwards to form respective small lateral conduits ( 22 ) which are positioned coaxially to the raws of secondary holes ( 15 ) The outer edges of such curved portions, wherefrom are departing lateral wings ( 23 ), terminate near the raws of primary holes ( 14 ) as well as slightly-spaced from the surface of the tubular cylindrical length ( 11 ) thus forming narrow slits. The air/gas fuel mixture comes from the secondary holes ( 15 ), it penetrates in the lateral conduits ( 22 ) and it goes out through the said narrow slits thus producing pilot flames ( F2 ) directed to the primary flames ( F1 ) which are produced by the primary holes ( 14 ).
