Non-volatile substances remain in the boiler water and are concentrated by this. Blowing down the boiler water then removes these substances in concentrated form and therefore efficiently from the cycle. In plant with forced circulation boilers, no water can be blown down--the feed water enters the boiler and leaves it as steam.
