CYCLONE PRIMARY FURNACE Russian patent published in 2012 - IPC F23C1/08 F23C7/02 F23C5/32 

FIELD: machine building.

SUBSTANCE: in cyclone primary furnace including combustion chamber (1); assembly of axial air supply to combustion chamber, which includes end swirl chamber; assembly of tangential air supply to combustion chamber, which includes cyclone-type box (12) and many tangential air nozzles (13) made in the form of openings in the wall of cylindrical part of combustion chamber; assembly of axial liquid fuel supply to combustion chamber, which includes an atomiser; assembly of axial gas supply to combustion chamber, which includes many nozzles of axial gas supply; assembly of side supply of gas to combustion chamber, which includes distributing gas header (8) mounted outside the box and connected to external gas source, and side gas supply tubes (14) which pass through the box in tangential direction; at that, the first end of each of the tubes of side gas supply is connected to distributing gas header, and the other end is open and made in the form of side gas supply nozzle (15) located inside the cavity of one of tangential air nozzles. The other end of each of the side gas supply tubes is bent at an acute angle from direction of tangential air supply to combustion chamber, which is provided with tangential air nozzle, in the direction to central axis of combustion chamber so that the bent section of side gas supply tube excludes internal visual clearance of side gas supply tube in the direction from one of its end to the other end.

EFFECT: increasing gas combustion efficiency, improving reliability of its operation and increasing service life.
