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.

High-pressure steam boilers create steam at above 15 psi. In practice, industrial high-pressure boilers often operate at hundreds of psi. They also operate at considerably higher temperatures than low-pressure boilers. High-pressure steam boilers are essential for providing higher energy transfer to down-stream point-of-use equipment.
Get PriceThis results in very high steam release rates per unit of water area, and turbulence. Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam. This means that even a small percentage blowdown can represent a high mass to be blown down. Water-tube boilers tend to operate at higher pressures, usually up to 150 bar g.
