GAS BURNER WITH DOUBLE CROWN FOR FLAME Russian patent published in 2019 - IPC F23D14/08 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering. Gas burner (100) includes a housing (B), which is designed with possibility to be located under the cooking top; block (A) filing, made with the possibility of attachment to the housing (B); central crown (C1) for a flame; and the peripheral crown (C2) for the flame, while the crowns (C1, C2) for the flame have a vertical axis, which coincides with the axis of the burner; moreover, supply unit (A) comprises at least one supply tube (1, 2) for supplying gas; the first, second and third nozzles (I1, I2, I3), which are connected to the at least one tube (1, 2); the first, second and third tubes (V1, V2, V3) Venturi, which are respectively connected with the specified nozzles (11, I2, I3), while the nozzles (I1, I2, I3) and tubes (V1, V2, V3) of the Venturi have parallel horizontal axes (X1, X2, X3); and fastener (4) used to attach the Venturi tubes (V1, V2, V3) and attach the specified feed unit (A) to the burner body (B); wherein said housing (B) of the burner comprises a central chamber (91), which communicates with said first tube (V1) of Venturi for supplying said central crown (C1) for a flame; and two peripheral cameras (51, 61), which respectively communicate with the indicated second and third (V2, V3) Venturi tubes and with the upper peripheral chamber (7) of a toroidal shape, which runs along the periphery relative to the indicated peripheral chambers (51, 61) and is located under the specified peripheral crown (C2) for the flame . In addition, the burner contains lid (3), made in one piece and mounted on the body (B) on the hob, while specified lid (3) contains holes (33), that define the specified central crown (C1) for the flame, holes (34) that define the specified peripheral crown (C2) for the flame, and intermediate part (32), which prevents secondary air from flowing outside the peripheral crown (C2) for the flame when it works peripheral crown (C2) for the flame; at the same time, when central crown (C1) for the flame and peripheral crown (C2) for the flame work, the flame of peripheral crown (C2) for the flame creates a barrier and stops the flow of secondary air to central crown (C1) for the flame, and the central crown (C1) for the flame only works with primary air delivered by the first Venturi tube (V1).

EFFECT: invention allows for the uniform supply and distribution of a mixture of gas and air in an outer crown for a flame.
