What is the function of the balancing chamber and minimum flow in the boiler feed water pump…

Feed water pumps (FWP) pump the feed water from the de-aerator through the HP heaters to the heat recovery steam generator. The major characteristic of the FWP is their high differential head. In all sizes of gas-fired combined-cycle power plants, the FWP are horizontal ring section type; occasionally, they could also be barrel or axially split type.

2017/12/8 · Boiler feed booster pumps are generally BB1 or BB2 configuration (see Figure 3.9) that have single-stage, double suction design and operate typically at four-pole motor speeds. The double suction impeller and low speed reduce the NPSHR of this pump type to suite the system design. The NPSHR by the booster pumps is much lower than that required
