Boiler Feed Water Pumps

Boiler Feed Water Pumps are used to supply water into the boiler.  The water may be fresh water or the water from the condenser.    The size of the Boiler Feed Water Pumps depends on the capacity of the boiler.

The operation of the Boiler Feed Water Pumps is dependent on the water level.  A level switch is used to switch the pumps on or off.

There are generally two pumps with one running and one as a standby.

Boiler Feed Water Pumps are of the centrifugal types.  They are usually multistage pumps.    The pumps are driven electrically or by a turbine.  Turbine driven pumps are preferred as the cycle efficiency of the boiler increases.
