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