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.

Abstract: PROBLEM TO BE SOLVED: To provide a simple and low-cost device for effectively mixing gas and reducing a back pressure in various boiler loads.SOLUTION: A gas mixing device has a plurality of interleaved rows of adjustable louvers. When at least two flowing gas streams are received that are desired to be mixed, the louvers of each row directs the gas streams in a direction different from that of the adjacent rows, mixing the gas streams. When effectively only a single flowing gas stream is received, the louvers are positioned vertically thereby reducing the pressure drop across the gas mixing device.

Abstract: A fuel nozzle assembly including a conduit defining a fuel inlet and a fuel outlet and being operable to convey a fuel stream comprising a solid particulate fuel entrained in a fluid. The conduit has a flow area defined by an interior surface of the conduit. A first flow deflector and a second flow deflector extend inwardly from the interior surface. The first flow deflector and the second flow deflector are positioned to disrupt a velocity profile of the flow stream established upstream of the conduit. - 14 ALSTOM Ref No. W10/047-1 MKG Ref, No. 1239-0090 --AD - * -.
