Boiler feed pump | KSB - Pumps, Valves and Service | KSB

Boiler feed pumps operate at fluid temperatures of 160 to 210 ºC. In exceptional cases the temperature of the fluid handled may be higher still. Feed pumps for 1600 MW nuclear power stations are constructed for mass flow rates of up to 4000 tonnes/h and feed pump discharge pressures of 70 to 100 bar.

Valve | KSB

The term "valve" stems from the Latin "valva", which means "moving part of a door". In piping technology, a valve is a piping component which controls, directs or mixes the fluid flow by opening, closing, diverting or partially obstructing the passage through itself. Valves are classified according to their basic design type (globe, gate, butterfly, ball or plug and diaphragm valves

BOILER FEEDPUMP RECIRCULATION

Therefore, the boiler feedpump recirculation valve will be in the closed position for 90% to 95% of the time in most power plants. This valve will also have the highest differential pressure across the seat of any other valve in the plant. This makes the recirculation valve one of the most severe duty valves in a generating plant.

Recirculation control valve replacement cuts maintenance

Boiler Feedpump Recirculation Valve The boiler feedpump recirculation valve faces some of the toughest conditions of any control valve in a power plant. The boiler feedpump takes its suction from the deaerator at relatively low pressure, and increases the pressure to approxi-mately 10 percent above the main steam pres-sure.

ARV or ARC Valves Introduction - wermac.org

As the 5300 ARC valve recirculates only that flow needed to cool a feed pump at critical times of low load rather than permitting a continuous recirculation flow, it saves the electrical power that continuous recirculation would consume, which can cost several thousand dollars per year.
