Practical considerations for modern BFW pumps

2015-8-11 · 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 to generate steam.

AllAboutFeed - Generating steam entails more than

The boiler output capacity given by the boiler manufacturers is by a maximum operation pressure and a feed water temperature of 100SDgrC or 102SDgrC. This implies that if the boiler feed water temperature is 80SDgrC and the boiler operating pressure is 8.5 Bar (Max 10.0 Bar) then the boiler can never produce the steam capacity given.
