FIELD: ring-type gas burners for kitchen gas-stoves. ^ SUBSTANCE: proposed gas burner has central body forming first ring of flame and at least one external body separated from central body relative to air and gas flow and located practically concentrically relative to it; it forms at least one second ring of flame for separate supply of mixture of primary air and gas to central body and to external body. Units for supply of external body have at least one horizontal mixing chamber each for forming Venturi effect. Burner is provided with one or many inlet holes for primary air which are located above ring and devices for admitting gases by communication of inlet holes with units for separate supply of mixture of primary air and gas to central body and to external body. Devices for admitting gases are made in form of single passage for supply of primary air directed to units for separate supply of mixture of primary air and gas. Unit for supply of central body is additionally provided with horizontal mixing chamber for forming radial Venturi effect. This mixing chamber is made in one external body and/or central body. ^ EFFECT: enhanced efficiency of burning gas; enhanced stability of flame ring and sensitivity of control of liberated heat. ^ 14 cl, 7 dwg |
