Abstract: 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.

Abstract: 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.

Abstract: A head assembly 52, 152 for a pulverized coal nozzle includes removeable wear-resistant inserts having vanes 54, 151, 153. The vanes 54, 151, 153 may be flat or curved to direct a stream of air and pulverized solid fuel particles from the inlet port 60, 160 toward the outlet port 62, 162. The curved vanes 151, 153 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 70, 170 that allows for easy access. The vanes are attached to a wear-resistant replaceable liner 185 thus allowing them to be easily removed and replaced. The wear-resistant liner 185 may be made from several parts 187, 189 for ease of removal and replacement.

Abstract: A system for sealing a port of a pulverizer. A pulverizer has journal assembly and a port for receiving the journal assembly. At least a portion of the journal assembly extends through the port. The system further includes a seal having a first end and a second end. The seal includes a first opening at or near the first end and a second opening at or near the second end. A bore extends between the first opening and the second opening. One of the first end and the second end is coupled to the pulverizer and the other one of the first end and the second end is coupled to the journal assembly. The seal inhibits fluid communication through the port.

Abstract: 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.
