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-1000-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.
