Abstract
The invention concerns a surface-combustion gas burner comprising a combustion grate consisting of a metal sheet pierced with a series of slots. This burner is remarkable in that said metal sheet comprises a series of deflectors made in one piece with said metal sheet and protruding on the outer face of same, each deflector extending longitudinally and laterally above the entire surface of a slot, and in that each deflector comprises a guide portion for guiding the gas flow and a junction portion joining to the metal sheet, said guide portion being spaced from the metal sheet in such a way as to provide therewith at least one lateral gas ejection port, said deflectors being disposed in pairs in such a way that the lateral gas ejection ports of same face each other.
Claims9
A surface combustion gas burner including a combustion grid consisting of a sheet made of metal or refractory material, perforated with a series of slits, said sheet including a series of deflectors formed integrally with said sheet and protruding from its outer face, each deflector extending longitudinally and laterally above the totality of the surface of a slit, each deflector including a gas flow guiding part and a part connecting it to the sheet, said guiding part being spaced away from the sheet so as to form with it at least one lateral gas ejection opening, and said deflectors being arranged in pairs, so that their lateral gas ejection openings face one another, wherein the combustion takes place at the outside face of the sheet, wherein said sheet is further perforated with a series of ports extending into discharging micro-tubes, which protrude from its outer face and the central axis whereof is perpendicular to the sheet, and wherein at least some slits and ports are grouped so as to form patters, each pattern including at least one port extending into a micro-tube positioned between two slits capped by a deflector,
- wherein said deflector is a bridge consisting of a strip of sheet metal having a central part and two ends attached to the two ends of the slit above which it extends, said central part constituting the gas flow guiding part and the two ends constituting the part connecting to the sheet, and in that two lateral gas ejection openings are formed on either side of said bridge,
- wherein the width of each bridge is equal to the width of the slit above which it is positioned.
