Disclosed herein is a novel pivot pin assembly (410, 420 430, 600) for pivotally attaching nozzle tips (200) to stationary nozzles in a solid fuel furnace. The pivot pin assemblies allow rapid replacement of the nozzle tips (200). The pivot pin assembly (410, 420 430, 600) employs fasteners that or recessed or have an aerodynamically shaped head (610). The head (610) includes a leading edge (613) and optionally a trailing edge (615) that are aerodynamically shaped to reduce corrosion and erosion. The pivot pin assembly pivotally attaches the nozzle tip (200) to the stationary nozzle (110). It employs fasteners that are accessible from a furnace side through a central opening of the nozzle tip (200). This allows removal of the nozzle tip (200) from inside the furnace greatly simplifying nozzle tip (200) replacement.
