boiler blowdown - wikipedia

Boiler blowdown - Wikipedia

Surface blowdown continuously bleeds off a low volume of water from within the boiler as a means of ridding the boiler of dissolved impurities. It is most effective to remove water with the highest level of impurities; and such water is found where steam separates in the steam drum at the top of the boiler.

the importance of boiler water and steam chemistry

The Importance of Boiler Water and Steam Chemistry

Carryover of impurities from boiler water to steam is also inherent to boiler operation. Though separation devices in drum boilers remove most water droplets carried by steam, some residual droplets containing small amounts of dissolved solids always carry through with the steam. Also, at higher pressures, there is some vaporous carryover.
