2016/3/28 · So in a 15,000 sq ft EDR system, where your pump is sized for 1 gpm per thousand square foot EDR, or 15 gpm, the boiler feed unit tank storage should be 15gpm times 5 minutes, or about 75 gallons of storage. A word about make-ups. The components of condensate return and boiler feed units are pretty much the same, with one noticeable difference.

Feed Pump Control and Feeder Valve Testing The operation of the feed pump control can be checked by observing the levels at which the pump starts and stops. It is advisable to either mark these levels on the water gauge or to measure the distances of the levels above the bottom of the gauge glass and to write them down in a log book for future reference.

Boiler. Boilers use the heat released during combustion to heat water or produce steam for heat supply or for driving a steam turbine, gas turbines or gas engines use gaseous energy carriers for generation of electricity and mechanical power, and internal combustion engines are used in vehicles (Sims, 2002).

A boiler feedwater pump is a specific type of pump used to pump feedwater into a steam boiler. The water may be freshly supplied or returning condensate produced as a result of the condensation of the steam produced by the boiler. These pumps are normally high pressure units that take suction from a condensate return system and can be of the

Alkalinity levels in the boiler are particularly important and these are controlled by the addition of sodium hydroxide. Maintaining a pH level of between 10.5 - 12 will avoid corrosion problems by providing stable conditions for the formation of a film of magnetite (Fe 3 O 4 ) in a thin, dense layer on the metal surfaces, protecting them from corrosive attack.
