Use proper water treatment to prevent the buildup of scale on the boiler. After scale has built up on the walls of the boiler it is almost impossible to remove it from the boiler. The introduction of acids in the pressure vessel is thoroughly discouraged, since virtually any solution that will chemically attack the scale will also attack the boiler metal.

Jun 18, 2014 · Then, in 1967, they further reduced the Pickup Factor from 1.33 to 1.15, but only for hot water boilers. They let the factor for steam boiler sizing remain at 1.33 because steam piping is bigger than hot water piping. This is because steam is bigger than water. There's one problem here, though. Steam pipes contain hardly any water.
