A boiler recovers heat from burned fuels. This is accomplished when high pressure boiler feedwater inside tubes located throughout the boiler is heated and turns into steam or hot water. The steam or hot water is then used in a variety of facility processes. Boiler feedwater often contains inorganic salts, dissolved impurities, and foreign particles, which generate corrosion problems and decrease efficiency due to damage to heat transfer surfaces. Demineralizers use ion exchange resins to remove these impurities in the raw water used for makeup in boiler feedwater.
