Steam Washing in boilers refers to the "washing" of the steam with fresh water or steam with condensate. The objective of steam water is to remove the impurities in steam such as silica. Silica in steam is mostly in the vapour state. Silica can deposit in the blades of turbines and affect the efficiency and the operation.
