Zusammenfassung:A coal nozzle for a burner on a pulverized coal fired furnace which includes an elongated tubular nozzle having an inlet for receiving a flowing stream of coal/air mixture and an outlet for discharging the flowing stream into a combustion zone of a furnace for combustion, and an inlet elbow connected to the inlet of the tubular nozzle. The interior outer surfaces of the elbow include a staircase surface configuration for engaging the incoming flowing stream whereby coal ropes in the stream are broken up for thereby improving flow distribution of the stream.
