Hot-Water- and Steam-Boiler Water Treatment |

2015-9-14 · 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.

Water Maintenance Essential to Prevent Boiler Scaling

When untreated boiler water is heated, this calcium and magnesium will precipitate from the solution to form hard scale on the tube surfaces. In addition to the overheating and eventual failure of the boiler tubes due to scale, efficiency is also decreased in the short-term because of the scale's insulating effect on the heat transfer surfaces.
