摘要： A fuel nozzle assembly including a conduit defining a fuel inlet and a fuel outlet and being operable to convey a fuel stream comprising a solid particulate fuel entrained in a fluid. The conduit has a flow area defined by an interior surface of the conduit. A first flow deflector and a second flow deflector extend inwardly from the interior surface. The first flow deflector and the second flow deflector are positioned to disrupt a velocity profile of the flow stream established upstream of the conduit.

摘要： 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.

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.
