26/3/2018 · Boilers that generate steam to power turbines require high-pressure boilers and therefore more complex feed water treatment system to remove as many impurities as possible. When steam is produced inside the boiler, the water particles collect and condense, then are recycled and used as part of the boiler feed water.
