FLARE DEVICE Russian patent published in 2015 - IPC F23G7/04 F23D14/00 

FIELD: machine building.

SUBSTANCE: flare device comprises a branch pipe for gas supply with a branch pipe for liquid supply set coaxially inside and fitted by a nozzle. A cup and a cylindrical casing are attached to the gas supply branch pipe by a flange joint. Gas withdrawal branch pipes are installed radially inside the cylindrical casing in one plane, and their inner ends project above the internal surface of the cylindrical casing. A flare device is fitted by an atomiser made as a Venturi nozzle. The atomiser is attached to the cylindrical casing by a thread connection. A fairing in the form of Coanda body is installed at the atomiser and fixed by a nut. Therewith a slot for gas escape is formed between the fairing and the cup. A swirler is set between the gas supply branch pipe and the cylindrical casing in the flange joint point. The flare device output is equipped by a recirculation unit made from two coaxial pipes with inner pipe being shorter than the outer one. A tapering branch pipe is mounted at the input of the recirculation unit and an expanding branch pipe is mounted at the outlet of the recirculation unit so that annular space is provided between the ends of the inner pipe and internal surfaces of the tapering branch pipe and expanding branch pipe as well as between the inner pipe and the outer pipe. An igniter is installed between the output end of the atomiser and the input of the recirculation unit.

EFFECT: higher quality of gas burning and liquid utilisation.
