Characteristics of boiler feedwater - Lennte

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. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica, phosphates etc, in relation to working pressure. The actual …

Heat Recovery from Boiler Blowdown TDS Control Only. Boiler water is blown down to control the amount of total dissolved solids (TDS) in the boiler. This water is pressurised, hot and dirty, creating large volumes of flash steam and possible disposal problems. A heat recovery system can reclaim large amounts of energy during this essential process.

Water Treatment (Steam Boilers) | CleanBoiler.o

Water quality is primarily an issue with steam boilers that use a lot of make-up water. Closed-system hot water boilers are the least effected by water quality because they use the least amount of make-up water and operate at lower temperatures. The common minerals in water that lead to scaling problems are iron, calcium, magnesium and silica.
