Hot-Water- and Steam-Boiler Water Treatment - HPAC Engineering

Steam boilers tend to be steel water-tube- or fire-tube-type boilers in the 10-to-1,000-hp range. Fire-tube boilers are more robust and more tolerant of poor water quality, but require more physical space, than water-tube boilers. Regardless of boiler type, water quality is a critical aspect of implementing and operating an efficient steam plant.
