Boiler Chemistry Control and Treatment of Feed Water

Silica needs to be controlled at DM plant also. The percentage of impurity allowed in boiler water/steam is function of boiler operating pressure, so, more critical for high pressure boilers. Two basic ways to regulate corrosion in water, are All Volatile Treatment (AVT) and Oxygenated Treatment (OT).

2019-10-14 · At 1000 psig, water density is only 20 times that of steam. In comparison with low-pressure boilers, the separating force is reduced by 83%, making entrainment possible at relatively low steam velocities. The cost of a drum adequately sized to separate steam and water at this higher pressure by gravity alone is prohibitive.

High Pressure Boilers: Features and Advantages ~ ME

A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
