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.

Water tube boilers experience heat flux rates as high as 250,000 Btu/hour/ft 2. This heat flux rate is far greater than boilers typically experienced when the ABMA limits were established. Combined with dimensional restrictions on modern units, this has raised the need for new guidelines to replace the outdated ABMA limits.
