Abstract: A solid fuel nozzle tip (201) having at least first (205) and second (207) ceramic shells is provided by the present invention. An inlet end of the first ceramic shell (205) is interconnected to a pulverized solid fuel nozzle (34), and an outlet end (301) of the first ceramic shell (205) is interconnected to an inlet end (305) of the second ceramic shell (207).

Abstract: An ignitor assembly for a fossil fuel-fired power generation system includes an elongate electrode, a tube sub assembly, and a coupling sub assembly, and an insulator sub assembly. The coupling sub assembly cooperates with other structural elements of the ignitor assembly and the respective windbox in which the ignitor assembly is installed to operably couple the elongate electrode to an external electrical power source. The ignitor assembly includes a contact socket secured by crimping to a lead of the external electrical power source which is biased into an electric current communicating disposition with the electrode rod of the ignitor assembly.

Abstract: A (MRFC) solid fuel nozzle tip (12) that is particularly suited to being cooperatively associated with a pulverized solid fuel nozzle (34) of a firing system of the type employed in a pulverized solid fuel-fired furnace (10). The MRFC solid fuel nozzle tip (12) includes fuel air shroud means (46), primary air shroud means (48) located within the fuel air shroud means (46), fuel air shroud support means (50) operative for supporting the primary air shroud means (48) relative to the fuel air shroud means (46), and splitter plate means (52) mounted in supported relation within the primary air shroud means (48). The MRFC solid fuel nozzle tip (12) may be comprised of ceramics including silicon nitride, siliconized silicon carbide, mullite bonded silicon carbide alumina composite, and alumina zirconia composites.

Abstract: Apparatus for cooperation with an associated coal burning furnace which includes a Y-shaped distributor body having one inlet and first and second outlets and a splitter disposed in the body for dividing flow between the first and second outlets. The splitter has a generally V-shaped contour and the splitter comprises a base on the housing and a liner assembly mounted on the base. In some forms of the invention the liner assembly has a surface that is harder than the surface of the housing and the housing includes a removable access panel. The access panel may be dimensioned and configured to allow passage of the liner assembly into and out of the housing. The liner assembly may comprise an outer shell having at least some foamed material disposed therein and may include anchoring means disposed in the foamed material.
