GAS BURNER Russian patent published in 1998 - IPC

FIELD: devices for burning gases in furnaces of thermally stressed technological plants; petrochemical, power and other industries; metallurgy. SUBSTANCE: collector of gas burner consists of cylindrical swirler rings of various diameters which are mounted coaxially relative to longitudinal axis of mixer; swirler rings are hollow on side of inlet; they have helical multistart passages on side of outlet to nozzle; direction of helical passages of all swirler rings is similar; swirler rings are divided by circular spaces for passage of air; connected to outer swirler ring on side of inlet on the outside are branch pipes for feeding the fuel gas; hollow cavities of intermediate rings and outer ring are interconnected by means of radial gas supply branch pipes; each ring consists of two half-rings: inner and outer half-rings tightly faying to each other; each half-ring is provided with multistart trapezoidal thread and hollow space; nozzle in form of truncated one is connected to mixer on side of outlet; larger base of this cone is oriented towards mixer; it may move along axis and may be fixed in preset position. EFFECT: enhanced efficiency of burning fuel gas in burner. 3 dwg
