    Table 9-6 lists the recommended limits for water-tube and fire-tube boilers without superheaters or turbines. High boiler water silica content can result in silica vaporization with the steam, and, under certain circumstances, siliceous scale. Silica content of the boiler water is not as critical for steam systems without steam turbines.Get Price

    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. The higher the pressure, the greater the energy contained in the blowdown water.Get Price

  • Silica in boiler water | Emerald Insight

    Steam contamination (solid particles in the superheated steam) comes from the boiler water largely in the carry‐over of water droplets.

Consequently, steam contamination has been steadily …Get Price
