COMBUSTION BURNER AND EQUIPPED WITH THIS BURNER BOILER Russian patent published in 2019 - IPC F23D1/00 

FIELD: power engineering.

SUBSTANCE: combustion burner contains a fuel nozzle, through which obtained by the fuel and air mixing with each other fuel gas is blown into the furnace; and plurality of separators made with possibility of the fuel gas flow separation by means of the expanded part, at that, the expanded part width increases as the expanded part passes in the fuel gas flow direction, at that, the separators are located in the fuel nozzle on the fuel nozzle distal end side so that the separators longitudinal axes pass from the fuel nozzle one wall part side to the another wall part side, which is located on the side opposite to the said one wall part, at that, plurality of separators include: grooved separators made with a groove, which partially reduces the expanded part width at the outlet end in the fuel gas flow direction, and separators without grooves made next to the grooved separators, at that, the separators without grooves have the expanded part, and the expanded part at the outlet end in the fuel gas flow direction has a fixed width in the longitudinal axis direction.

EFFECT: invention enables to reduce the NO_x emission.
