Abstract: A low NOx swirling pulverized coal burner includes a secondary air box (3). A primary air duct (1) is centrally and longitudinally disposed in the secondary air box (3). Conic ring-shaped pulverized coal separators (2) are fixed in the primary air duct (1) with the respective minor diameter ends thereof directing towards the outlet end of the primary air duct (1). An inner secondary air duct (9) and an outer secondary air duct (10) are disposed outside the primary air duct (1). An inner swirler (4) is fixed in the inner secondary air duct (9). The outlet ends of the primary air duct (1), the inner secondary air duct (9) and the outer secondary air duct (10) are connected to the minor diameter ends of a conic ring-shaped primary air duct divergent outlet (11), a conic ring-shaped inner secondary air duct divergent outlet (12) and a conic ring-shaped outer secondary air duct divergent outlet (13), respectively.
