Abstract: A nozzle tip (100) for a pulverized solid fuel pipe nozzle (200) of a pulverized solid fuel-fired furnace includes: a primary air shroud (120) having an inlet (102) and an outlet (104), wherein the inlet (102) receives a fuel flow (230); and a flow splitter (180) disposed within the primary air shroud (120), wherein the flow splitter disperses particles in the fuel flow (230) to the outlet (104) to provide a fuel flow jet which reduces NOx in the pulverized solid fuel-fired furnace. In alternative embodiments, the flow splitter (180) may be wedge shaped and extend partially or entirely across the outlet (104). In another alternative embodiment, flow splitter (180) may be moved forward toward the inlet (102) to create a recessed design.
