Learn MoreUse proper water treatment to prevent the buildup of scale on the boiler. After scale has built up on the walls of the boiler it is almost impossible to remove it from the boiler. The introduction of acids in the pressure vessel is thoroughly discouraged, since virtually any solution that will chemically attack the scale will also attack the boiler metal.
Get pricehi pressure boiler Agent tds chart 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.
