Water Handbook - Preboiler & Industrial Boiler Corrosion .

Maintenance of proper pH throughout the boiler feedwater, boiler, and condensate systems is essential for corrosion control. Most low-pressure boiler system operators monitor boiler water alkalinity because it correlates very closely with pH, while most feedwater, condensate, and high-pressure boiler water requires direct monitoring of pH.

Municipal or plant water of good quality for domestic use is seldom good enough for boiler feed water. These sources of makeup are nearly always treated to reduce contaminants to acceptable levels; in addition, corrective chemicals are added to the treated water to counteract any adverse effects of the remaining trace contaminants.

Boilers must have a proper pressure-relief valve, located at the top, which opens when the pressure reaches 30 pounds to prevent the boiler from exploding. If you ever see water draining out of the relief valve, chances are that the system is operating under excessively high pressure and should be checked by a professional.

Difference Between Low- and High-Pressure Boilers | Hunk

A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.
