PRIMING & FOAMING Foaming It is the production of foam or bubbles in boiler which do not break easily. Causes of Foaming : It is due to the presence of oily substances in water. Prevention of Foaming : (1) By the addition of anti-foaming chemicals like castor oil, Gallic acid, tannic acid etc. (2) removing oil from boiler water by adding compounds like sodium aluminate.
