As the feed water evaporate into steam, dissolved solids concentrate in the boiler. Above certain level of concentration, these solids encourage carryover of water into steam. This leads to scale formation inside the boiler, resulting in localised over heating and ending finally in tube failure. Hence blow-down is very much required for boilers. 6.Get Price
Feed-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.Get Price

Aug 10, 2021 · If the maximum set point for conductivity (a measurement of dissolved solids) is 3,500 uS and the incoming makeup water conductivity is 700 uS, you can only concentrate the water five times before blowdown becomes necessary. This results in 20% of the heated boiler water quite literally going down the drain.Get Price
Sep 28, 2021 · The water used for steam generation is known as boiler feed water that contains impurities that do not boil off with steam and concentrate in the boiler water.
