An outer shroud for a solid fuel nozzle tip includes: an top shell portion and a bottom shell portion, each portion fabricated from a preform produced from a single sheet of flat stock and each shell portion including a forward area and a backward area and outlet sidewalls, wherein a right outlet sidewall and a left outlet sidewall are each separated from the forward area by a rounded corner; and a left inlet sidewall and a right inlet sidewall coupled to the top shell portion and the bottom shell portion.

Coal nozzle tip shroud

An apparatus () operative for purposes of detecting the presence of a coal rope within a coal delivery pipe () is provided. The apparatus () includes a rod () that is operative to flex when struck by a coal rope that is present inside the coal delivery pipe (), a strain gauge () that is operative to produce an electrical signal based upon the amount of flexing that the rod () is subjected to when struck by a coal rope that is present in the coal delivery pipe (), and a processor that is operative to determine based upon the electrical signal that is received thereby from the strain gauge () at least one of either the location of the coal rope within the coal delivery pipe () or the density of the coal rope within the coal delivery pipe ().

Device for identifying the location of coal ropes

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

Multiple segment ceramic fuel nozzle tip

A riffle distributor assembly for influencing the travel properties of a material feed streammoving between a pulverizerand a furnaceis part of a feed pathhaving one ductA having a branch entryA and another branch ductC having a branch entryC both downstream of upstream passage peripheries UPZ defined between adjacent intake vanesthrough which the feed stream of the materialtravels in two segregated portions. A motor drive assemblymoves the intake vanesrelative to the incoming flow reference axis IFA, whereupon intake areas defined between adjacent intake vanesmoves relative to the incoming flow reference axis IFA such that the travel properties of the one portion of material in the one branch ductA are different than its travel properties before the movement of intake areas defined between adjacent intake vanes

Riffle distributor assembly for a fossil fuel fired combustion arrangement

A pivot mounting apparatusis provided for pivotally mounting to one another the coal nozzle tipand coal nozzle bodyof a pulverized solid fuel nozzleof a pulverized solid fuel-fired furnace. The pivot mounting apparatusincludes a latch interconnecting assemblythat includes a pinfor insertion in a traversing movement through an insertion passagewhich passes through both the through holeof the coal nozzle tipand the through holeof the coal nozzle bodyupon the mutually facing positioning of respective sides of the coal nozzle tipand the coal nozzle bodywith one another with their respective through holesboth co-axial with an insertion axis IAX.

Fuel nozzle for a fossil fuel fired combustion arrangement

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