| 摘要 |
The present invention relates to a gas burner that includes an air inflow region (4) consisting of a lower section (6) abutting a gas-feeding duct (1) and of an upper section (7) abutting the previous one. Each section is made of a peripheral cylindrical wall (8, 9) and a base (11, 12) that comprise openings (13, 15) for feeding the air sucked in by the injection effect. A slot grid (18) made of ridges (19) arranged on a vertical plane is mounted in the lower section (6), while a slot grid (21) similar to the first one is mounted in the upper section (7). The ridges (22) of the second grid (21) are arranged on a vertical plane so as to define an angle of preferably 90 DEG relative to the plane of the lower ridges. A mixing chamber (5) abutting the air inflow zone (4) comprises a longer diverging section and a shorter converging section, while a disc (27) fitted with micro-nozzles (29) is further mounted on the outlet plane of the last section. |
