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.
