Boiler feedwater - Wikipedia, the free
Boiler water is treated to prevent scaling, corrosion, foaming, and priming. The dry pipe is where the steam and water mixture are separated. In deaerating heaters steam sprays incoming feed water and carries away the dissolved gases. Large cation/anion ion exchangers used in demineralization of boiler feedwater.
