boiler water ph

Boiler Corrosion and Its Effects | How To Prevent

The ideal pH for feedwater is between 7 and 9, slightly alkaline. To keep the water within this range, you will need to add either sodium phosphate salts or sodium hydroxide. Unfortunately, you cannot directly monitor the pH inside the heat of the boiler. Rather, you must measure pH from a cooler, lower-pressure side stream.

Hot-Water- and Steam-Boiler Water Treatment | HPAC Engineering

Steam boilers tend to be steel water-tube- or fire-tube-type boilers in the 10-to-1,000-hp range. Fire-tube boilers are more robust and more tolerant of poor water quality, but require more physical space, than water-tube boilers. Regardless of boiler type, water quality is a critical aspect of implementing and operating an efficient steam plant.
