The salinity will rise rapidly since the salt remains in the boiler while the water boils off. Salt will son precipitate and accumulate on the bottom and also on the heating surface where it, just as boiler-scales, inhibit the heat transmission to the water and causes the metal to overheat and in worst case burst.

Classification of boilers – High-pressure boilers are boilers operating at a steam or other vapor pressure in excess of 15 psig, or a water or other liquid boiler in which the pressure exceeds 160 psig, or has a temperature greater than 250 degrees Fahrenheit. Others are low-pressure boilers. License requirement

Nov 29, 2012 · There is a limit on maximum amount of salinity which a boiler water can sustain. If this value exceeds than normal then there is a risk of formation of larger bubbles. Larger the bubbles produced greater the turbulence on water surface and this causes foaming. This foam may be carried with steam and can cause deposits.

Kefid · • Softening of water containing high salinity (e.g. softening of sea water) • Removal of heavy metals from water/waste water. Dealkalisation: WAC resins can be used for removal of alkalinity from water 1. Low/medium pressure boiler feed water: High alkalinity in boiler feed waters may necessitate a high blowdown from the boilers.

Boiler – Fundamentals and Best Practices

High conductivity or contamination of the boiler feedwater can create other problems such as drum level instability and foaming. This can result in high or low-water alarms and an increase in the carryover of moisture droplets into the steam header since the moisture separator of the drum cannot handle the resultant carryover.
