Boiler feed pumps locating

Steam condensate at 1 atm and 95°C (Pv = 526 mmHg) is returned to a boiler from the condenser by a centrifugal boiler feed pump. The flow rate is 100 gpm through a 2.5 in. sch 40 pipe. If the equivalent length of the pipe between the condenser and the pump is 50 ft, and the pump has an NPSH of 6 ft, what is the maximum height above the condenser that the pump can be located ...

Because boiler feed pumps take water from a deaerator and generally operate close to the vapor pressure of the liquid, they must be located as close to the deaerator as possible. [Pg.187]

Boiler Feed Water System—Check the demineralised water plant units, water piping, operation of water pumps, condensate recycle lines, deaerator tank, drain lines, calibration of Boiler Feed Water tank, operation of level indicator, external insulation, location of temperature indicators, etc. Get examined the hydraulic test certificates for all pressure parts and subsequentiy obtain permission from Statutory Boiler Inspection Authority to commission the boiler. Note BFW pumps shall be run one by one to feed water into the boiler. Backpressure shall be created by throttiing overflow from WHB. Water flow... [Pg.80]

ECONOMIZER - A series of tubes located in the path of flue gases. Feed water is pumped through these tubes on its way to the boiler in order to absorb waste heat from the flue gas. [Pg.64]
