oxygen scavengers. Oxygen scavengers are reducing agents that react with even the very low levels of oxygen left in water by good deaeration. They are normally added to the storage section of the deaerator, to allow time for reaction before the feedwater reaches the boiler. Low pressure boilers sometimes do not include mechanical deaerators. In

Practical considerations for modern BFW pumps

Aug 11, 2015 · Another form of BFW pump capacity control runs constantly and is provided with a minimum flow device to stop overpressuring the pump on low flows. The minimum flow usually returns to the tank or deaerator. This is only used for relatively small BFW pumps. Boiler feed water. Boiler feed water is used to supply ("feed") a boiler …

High Pressure Boilers: Meaning, Types, Characteristics

The feed water from the hot well is pumped by the feed pump through the economiser and preheated water is supplied to the boiler drum. The water is heated up by the hot gases flowing in the upward direction, which are later exhausted through the chimney high in the atmosphere to reduce air pollution.

Practical considerations for modern BFW pumps

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 centrifugal pump type or positive displacement type.
