GAS BURNER Russian patent published in 2013 - IPC F23D14/06 

FIELD: power engineering.

SUBSTANCE: gas burner (10) comprises the first burner device (18) of low capacity and the second burner device (16) of high capacity, besides, burner devices (16, 18) are made as capable of sucking in the primary air above a bearing panel (14), forming the upper wall of a cabinet in a gas kitchen cooker (12), and formed by a lower body (59), by the first flame crown (40) for the burner device (18) of low capacity, the second flame crown (52) for the burner device (16) of high capacity and an upper cover (11), which are arranged coaxially one above the other, at the same time each of burner devices (16, 18) comprises an inlet gas pipeline (28, 30), an injector (34A, 34B, 46), a Venturi pipe (38A, 38B, 50) and several holes (44, 56) to discharge gas, besides, holes (44) to discharge gas of the burner device (16) of high capacity have larger dimensions compared to the holes (56) to discharge gas of the burner device (18) of low capacity, and a temperature sensor (63) to measure actual temperature of a heated reservoir (26) to cook food, at the same time the upper cover (11) comprises an upward protruding ring-shaped section (65), which surrounds the temperature sensor (63) and acts as a thermal shield. The temperature sensor (63) is located in a through hole, which stretches via centres of the first flame crown (40), the second flame crown (52) and the upper cover (11).

EFFECT: invention makes it possible for a burner device to operate in a wide range of capacities.
