Abstract
A coal nozzle assembly for a pulverized coal burner includes a diffuser. A flow conditioner also may be used with the assembly. The assembly conditions the coal/air flow before the coal/air flow is introduced to the furnace. The flow conditioner directs the coal into the diffuser where it is swirled to form a fuel rich outer ring disposed about an air rich inner portion before the fuel is delivered to the coal nozzle.
