PULVERISED-COAL MIXTURE SUPPLYING ATOMISER Russian patent published in 2009 - IPC F23D1/00 

FIELD: heating systems.

SUBSTANCE: invention refers to heat engineering and can be used for arrangement of combustion of pulverised fuels when high-concentration pulverised coal mixed with air, also called air-and-coal mixture, is supplied to burner or directly to burner flame. The effect is achieved in atomiser containing the tube supplying air-and-coal mixture to burner or to burner flame, in which there arranged is swirler and cone divider installed in outlet section of tube and facing with its vertex of cone the air-and-coal mixture flow; at that, on side surface of tube outlet section, in divider installation place there provided are at least two openings for discharging air-and-coal mixture jets, and swirler itself is located in direction of air-and-coal mixture flow before openings and vertex of cone of divider.

EFFECT: providing uniform distribution of air-and-coal mixture as to spraying angle when it is injected, and providing bigger depth of penetration of pulverised-coal jets into concurrent air flow of burner.
