FIELD: power engineering.SUBSTANCE: system (1) of burners of a domestic gas cooker, comprising a channel (2) of gas supply into the system (1) of burners, the first and second reservoirs (2A, 2B), connected to the channel (2) via at least one pair of nozzles (2C, 2D), in particular, via the first nozzle (2C) and via the second nozzle (2D), a pair of substantially concentric burners (3, 4), comprising an outer burner (3) and an inner burner (4), besides, gas supplied into the pair of burners (3, 4) is capable of mixing in the first reservoir (2A) and the second reservoir (2B) with the primary air taken above a cooking panel (8), where the system (1) of burners is installed, to create the gas and air mixture for the pair of burners (3, 4). The system comprises a pair of chambers (10) with Venturi effect, arranged at diametrically opposite sides relative to the central axis (A) and made as capable of directing the gas and air mixture in direction of the outer burner (3) and the inner burner (4), at the same time each chamber (10) has appropriate first axis (10A), inclined towards the central axis (A) of the system (1) of burners, besides, the first axis (10A) of each chamber (10) crosses the central axis (A) in the point located above the cooking panel (8). The angle of inclination of the first axis (10A) relative to the central axis (A) of the system (1) of burners makes from 5° to 25°, and preferably from 12° to 14°. The pair of nozzles (2C, 2D) has the second axis (2E), inclined towards the central axis (A) of the system (1) of burners. The second axis (2E) substantially matches the first axis (10A) of the pair of chambers (10) with Venturi effect.EFFECT: invention makes it possible to optimise efficiency of burning in a system of burners.21 cl, 2 dwg |
