A nozzle tip for a pulverized solid fuel pipe nozzle of a pulverized solid fuel-fired furnace is provided. The nozzle tip includes a primary shroud having an inlet end and an outlet end, and an outlet at the outlet end for the passage of a pulverized solid fuel into the furnace. An area of the outlet is selectively adjustable to vary an exit velocity of the pulverized solid fuel from the nozzle tip.
