Effects of High TDS Levels in Feed Water to Boiler

Increase in the TDS concentration in boiler feed water leads to increased scale formation or deposition on the tube surface, which act as a resistance in transferring heat from flue gases to the water, which further leads to overheating of the tubes. Boiling is a bulk phenomenon that occurs throughout the liquid, so at initial stages bubbles
