PULVERISED-COAL BURNER WITH AERODYNAMIC CONVERTER OF AIR-AND-COAL MIXTURE FLOW Russian patent published in 2009 - IPC F23D1/06 

FIELD: heating systems.

SUBSTANCE: invention refers to heat engineering and can be used as a pulverised-coal burner for the boilers of thermal power stations and industrial boiler houses. This is ensured by the fact that the aerodynamic converter installed in an annular duct meant for supplying air-and-coal mixture after the swirler in the direction of air-and-coal mixture is made in the form of at least three longitudinal radial partitions uniformly located in a circumferential direction of annular duct, and parallel once-through ducts forming a system.

EFFECT: simplifying the design, increasing fuel ignition velocity and efficiency of fuel combustion during two-stage pulverised coal combustion at maintaining the reduced output of fuel nitrogen oxides.
