摘要： A head assembly for a pulverized coal nozzle includes removeable wear-resistant inserts having vanes. The vanes may be flat or curved to direct a stream of air and pulverized solid fuel particles from the inlet port toward the outlet port. The curved vanes curve in two dimensions to evenly distribute the stream of air and pulverized solid fuel away from the outer surfaces reducing wear and corrosion. The pipe elbow has a removable cover that allows for easy access. The vanes are attached to a wear-resistant replaceable liner thus allowing them to be easily removed and replaced. The wear-resistant liner may be made from several parts for ease of removal and replacement.

摘要： A head assembly 52,152 for a pulverized coal nozzle includes a turning vane 54 or a curved vane 154 disposed within a pipe elbow. The vanes 54,154 are angled relative to the inlet port and the outlet port of the pipe elbow to redirect a stream of air and pulverized solid fuel particles from the inlet port 60,160 toward the outlet port 62,162. The coal rope-breaking vane 56 is pivotable about an axis to adjust an angle of the vanes relative to a stream of air and pulverized solid fuel particles from the inlet port 60,160. An adjustment bar 66 may connect to the vanes 56 and extend outward through the pipe elbow to allow the vanes 56 to be adjusted while the pulverized solid fuel particles flow through the head assembly 52. The pipe elbow may further include inspection ports 68,168 and a removable cover 70,170. The vanes may be attached to the removable cover 70,170 thus allowing them to be easily removed and replaced.

摘要： A wear plate assembly includes a body portion and an abutment flange extending from a radially outer circumferential edge of the body portion and substantially normal thereto. The abutment flange is cooperatively configured with respect to another abutment flange of a respective adjacent wear plate that interengages with the wear plate such that a convoluted edge of the another abutment flange of the respective adjacent wear plate intermeshes with a respective convoluted edge of the abutment flange of the wear plate. At least one polygonal recess and a corresponding abutment ramp are substantially aligned therewith at a same latitude on the body portion, the recess further includes a through hole extending through the wear plate. A first clip configured is partially received in the polygonal recess, the clip having a plurality of exposed impact surface faces.

摘要： A flow control apparatus for a coal pipe containing a stream of primary combustion air carrying pulverized solid fuel particles, includes a frame sealingly secured to an outside surface of the coal pipe around a window opening formed on one side of the pipe. An orifice plate having an orifice opening at the center is supported for pivotal movement in the coal pipe on a spindle extending radially outwardly from an edge portion on one side of the orifice plate and out through the window opening in the pipe. A bearing sleeve is provided for supporting the spindle for rotating movement about a spindle axis extending transversely of the coal pipe across the center thereof. A mounting plate structure for the sleeve is provided and is attached to the frame. A removable handle is attached on an outer end of the spindle for rotating the orifice plate in the coal pipe to vary the effective flow cross-section of the orifice opening for controlling the flow of coal and primary air to a burner.

摘要： A simple, economical and reliable swirl register [1000] is described for use with a wall burner of a commercial boiler. It employs a number of spaced swirl blocks [1150] that connect side plates [1110, 1120]. A number of moveable vanes [1130] are provided in the air ducts [1155] created between the swirl blocks [1150]. The vanes [1130] are attached to vane rods [1160] that operate the vanes [1130]. The swirl blocks [1150] are lightweight and rigid structures for holding the side plate [1110] a fixed distance from side plate [1120]. The block construction reduces binding of the vanes [1130] as the swirl register [1000] receives differential heating. The vane rods [1160] extend through a windbox front plate [1250] outside of the windbox area. A linkage assembly [1200] rotates the vane rods [1160]. A motor and gearbox [1230] cause all vanes [1130] to rotate the same amount.
