摘要： A pulverized solid fuel nozzle assembly (34) includes a fuel feed pipe (38) and a nozzle tip (36) pivotally secured relative to the fuel feed pipe (38). The fuel feed pipe (38) includes a generally cylindrical shell (99) having a round outlet end (102) and a bulbous protrusion (106) disposed around a perimeter of the round outlet end (102). The nozzle tip (36) includes an inner shell (40) having a round inlet end (108) arranged in concentric relationship with the round outlet end (102) of the generally cylindrical shell (99). The round inlet end (108) is disposed around the bulbous protrusion (106) for forming a seal between the inner shell (40) and the fuel feed pipe (38). The nozzle tip (36) also includes an outer shell (39) arranged in coaxial relationship with the inner shell (40), and an annular air channel (42) disposed between the inner and outer shells (40), (39). The nozzle tip (36) is pivotable about at least one axis (52), (250) for directing a stream of pulverized solid fuel from the inner shell (40).
