COMBUSTION BURNER AND BOILER EQUIPPED WITH SUCH BURNER Russian patent published in 2018 - IPC F23D1/00 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering. Burner for combustion comprises a fuel injector capable of injecting a fuel gas in which fuel and air are mixed; at least one flame stabilizer provided from the end of the fuel injector near the central axis; and a separating member separating the inner flow passage in which the flame stabilizer is provided and an external flow passage from the outside of the inner flow passage within the fuel injector; cross-sectional area of the inner flow passage separated by the separating element increases in the direction of the flow of the fuel gas. Separating element is an element in form of a casing. Separating element has two plate-shaped bodies that extend mutually, providing a distance with the flame stabilizer positioned between them, plate-shaped bodies being attached to the wall surface, delineating the outer periphery of the fuel injector.

EFFECT: invention allows to achieve stable ignition and reduce the amount of nitrogen oxides formed.
