Abstract
A head assemblyfor a pulverized coal nozzle includes a turning vaneor a curved vanedisposed within a pipe elbow. The vanesare 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 porttoward the outlet port. The coal rope-breaking vaneis 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. An adjustment barmay connect to the vanesand extend outward through the pipe elbow to allow the vanesto be adjusted while the pulverized solid fuel particles flow through the head assembly. The pipe elbow may further include inspection portsand a removable cover. The vanes may be attached to the removable coverthus allowing them to be easily removed and replaced.
