FIELD: power industry.
SUBSTANCE: surface combustion gas burner comprises a combustion grate consisting of a sheet (1) made of metal or heat resistant material pierced with a series of slits (2), wherein the said sheet comprises a series of deflectors (3, 3a, 3b, 3', 3") protruding on its outer surface (12), wherein each deflector (3, 3a, 3b, 3', 3") comprises a guide portion (30, 30') for guiding the gas flow and a junction portion (31, 32, 33', 33") joining to the sheet (1), wherein the said guide portion (30, 30') being spaced from the sheet (1) in such a way as to provide therewith at least one lateral gas ejection port (40, 40', 41). The said deflectors (3, 3a, 3b, 3', 3") being disposed in pairs in such a way that the lateral gas ejection ports (40, 40, 41) of same face each other, the deflectors (3, 3a, 3b, 3', 3") are formed integrally with the said sheet. Each deflector extends longitudinally and transversely above the totality of the surface of a slit (2), wherein in the said sheet (1) is further perforated with a series of ports (5) extending into discharging micro-tubes (6) which protrude from its outer surface (12), wherein the central axis (Z-Z') of the said micro-tubes (6) is perpendicular to the sheet, wherein the gas burner comprises patterns (7, 7') grouping the slits (2) and the ports (5). Each pattern comprises at least one port (5) facing in the micro-tube (6) located between two slits (2) above which there is a deflector (3, 3a, 3b, 3', 3").
EFFECT: invention allows flame stabilization, extending service life of the burner, reducing of the emission of harmful substances into the atmosphere.
