: 272KB: 129KBFeed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica

Boiler Water Quality Boiler Chemicals are used to ensure proper Boiler Water Quality in boilers. The below table is the Total Dissolved Solids or TDS, Alkalinity, and Hardness versus Boiler Pressure. First, knowing the water source is important, whether it is from ponds, rivers, ground wells, or city water.
