As an example, such a feed pump could be designed with a flow rate of about 4200 m3/h and a head of about 700 m at a rotational speed of 5300 rpm. See Fig. 5 Boiler feed pump. Heads of reactor feed pumps are in the region of 800 m for boiling water reactors and 600 m for pressurised water reactors.

Boiler Feed Pump Calculator - Pipeng Toolbox

Calculate boiler feed pump power from pressure and flow rate (IAPWS R7-97 Steam Table). Boiler feed pump power equals the volume flow rate times the pressure difference. The efficiency factor accounts for the pump efficiency. For hydraulic power set the efficiency factor to 1. For pump break horsepower set the efficiency factor less than 1.

Boiler Feed Water Pump Working Principle and Operation

The duty of the boiler feed pump as determined by the boiler and turbine pressure flow conditions, is given by Fig 1.71.Shown on the diagram are the boiler feed-pump characteristics, i.e., the relationships between the head produced by the boiler feed pump corresponding to the particular value of feed flow pumped, and the boiler feed pump speed.
