PIVOT PIN FOR FURNACE SIDE REMOVAL

摘要

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.
