Abstract: 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.

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 electronic device carrier (110) adapted for transmitting high-frequency signals, including a circuitized substrate with a plurality of conductive layers (240a to 240g) insulated from each other, the conductive layers being arranged in a sequence from a first one of the conductive layers (240a) wherein a plurality of signal tracks (200) each one ending with a contact area (205) for transmitting a high-frequency signal are formed, and a reference structure (215a, 215b, 230) connectable to a reference voltage or ground for shielding the signal tracks the reference structure includes at least one reference track (230) formed in a second one of the conductive layers (240b) adjacent to the first conductive layer and at least one further reference track formed in one of the conductive layers (240d) different from the first and second conductive layer, a portion of each signal track excluding at least the area corresponding to the orthographic projection of associated contact area being superimposed in plan view t

Abstract: A pivot mounting apparatus 210 is provided for pivotally mounting to one another the coal nozzle tip 212 and coal nozzle body 214 of a pulverized solid fuel nozzle 208 of a pulverized solid fuel-fired furnace 10. The pivot mounting apparatus 210 includes a latch interconnecting assembly 220 that includes a pin 222 for insertion in a traversing movement through an insertion passage 224 which passes through both the through hole 216 of the coal nozzle tip 212 and the through hole 218 of the coal nozzle body 214 upon the mutually facing positioning of respective sides of the coal nozzle tip 212 and the coal nozzle body 214 with one another with their respective through holes 216, 218 both co-axial with an insertion axis IAX.
