16/7/2009 · Effects. In case layers of scales keeps on building inside the boiler, the insulation layer will reduce, which in turn will prevent the heating of water and generation of steam.This will lead to overheating and damage to the internal parts of the boiler, reducing the overall efficiency. 3. Oil and fats.

Deposits of a porous nature allow boiler water to permeate the deposits, causing a continuous buildup of boiler water solids between the metal and the deposits. Because caustic soda does not crystallize under such circumstances, caustic concentration in the trapped liquid can reach 10,000 ppm or more.
