2 Large Vertical Circulating Water Pumps Tough Jobs. Tougher Pumps. • Power generation cooling (main, intermediate and secondary water circulation) • Condenser cooling with maximum efficiency • Desalination sea water intake across the globe • Flood protection in storm ravaged areas • Waste treatment plants (industrial and municipal)
Boiler feed pumps (BFPs) consist of feeding to a steam generator (e.g. boiler) a quantity of feedwater corresponding to the quantity of steam generated. Operating parameters (flow, head, temperature) of boiler feed water are calculated by a boiler designer. Today, almost all BFPs are centrifugal pumps. The construction of BFPs in …
Circulating Water Systems at any power plant have two important functions: Filter water before it is pumped to and through the condenser; Cool the condenser; Major Components. Intake (Supply) Basin. Water is supplied from an abundant source - river, lake, sea, or ocean - to a storage basin which, in turn, supplies the large pumps. Trash Racks
Boiler circulating pumps are designed for high temperatures (usually between 150 C and 315 C [300 F and 600 F], depending on boiler size and rating) and …
