As steam is produced, dissolved salts remain in the boiler and continue to concentrate. Some salts may be soluble in the bulk boiler water. However, the boiler water immediately at the tube surface is considerably hotter than the bulk boiler water. As steam bubbles form near the tube wall, the soluble salts remain with the boiler water.

High Pressure HRSG and Co-Generation Water-Steam …

Boiler Water Treatment . In the 1930s as steam generator technology evolved and high-pressure units grew in numbers, tri-sodium phosphate (TSP, Na 3 PO 4) became the common chemical for boiler water treatment as it generates alkalinity (caustic, NaOH) to protect against corrosion. Also, phosphate reacts with hardness compounds to reduce the

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. GET A QUOTE
