Water and steam chemistry deposits and corrosion-

May 25 2016 · Therefore to protect vessels tubing and other components used to contain and control these working fluids water and steam chemistry must be controlled. Water used in boilers must be purified and treated to inhibit scale formation corrosion and impurity contamination of steam. Two general approaches are used to optimize boiler water chemistry.

Chemistry Parts: Steam Boiler

Mechanism of Deposition In any steaming boiler three basic conditions exist: 1. A circulation pattern is developed in the boiler due to steam bubbles which alter the density of the boiler water. The hottest area of the boiler (where nucleate boiling occurs) is where the steam-boiler water mixture is the least dense.
