A system for reheating a power generation system including a boiler having a waterwall and a steam drum with an input fluidly coupled to the waterwall and an auxiliary heat source to provide heated fluid. The system also includes a first flow control valve connected to the auxiliary heat source and the boiler to control a flow of heated fluid from the auxiliary heat source to the waterwall; a first isolation valve disposed at a waterwall, to isolate circulation of heated fluid from the steam drum to the waterwall; and a sensor to monitor at least one operating characteristic in the boiler. The system also includes a controller to control at least one of the flow control valve, the isolation valve, and the auxiliary heat source to control the amount of heated fluid supplied to the waterwall when the boiler is not generating steam.

System and method for improving startup time in a fossil-fueled power generation system

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 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.
