FIELD: machine building.
SUBSTANCE: gas burner for gas stoves consists of case (2) with one or several rings (3B, 3C), Venturi tube (4), gas line (1) horizontally or vertically installed inside case and ended with sprayer (5) for supply of gas flow from gas line (1) into tube (4), and device for suction of flow of primary air along two different ways of supply. Also, the first way is formed with air duct (6) located around gas line (1) and coaxially to it thus creating extended circular internal space (7). The second way is formed with through orifice (8) located downstream after sprayer (8) and before an inlet orifice of Venturi tube (4). Coaxial air duct (6) is designed for drawing primary air from internal space of the stove, while orifice (8) is designed for suction of corresponding primary air coming from an upper section of the stove. The burner is equipped with a device for air turbulisation swirling a flow of primary air in coaxial air duct (6). This device is located inside extended circular internal space (7). The said device runs from external surface of gas line (1) to internal surface of coaxial air duct (6).
EFFECT: double suction of primary air both from inside of stove case and outside from space over stove.
