Steam Boiler: What is Alkalinity?

Alkalinity is a key control parameter for boilers (outside of the prescribed operating range, it can lead to corrosion, caustic metal embrittlement, and carryover) and cooling water systems (where it has a significant effect on chemical treatments for scale and corrosion inhibition).

Boiler Water Conditioning | PDF | Steam | Boiler

A Boiler is a closed vessel inside which water is stored, heated and circulated, either as hot water, steam or superheated steam for the purpose of heating, powering and/or producing electricity. The furnace of the boiler is where the fuel and air are introduced to combust; fuel/air mixtures are normally introduced into the furnace by using burners, where the flames are formed.

Asking him about the pH factor, he stated that for each whole number it moves, the solution has doubled in concentration. An example: water that has a pH of 8 is alkaline, but a water of pH 9 is twice as alkaline. A water of pH 10 is twice as alkaline as 9.

Water for the Boiler | Spirax Sarco

Water-tube boiler plant is much less tolerant of high TDS levels, and even less so as the pressure increases. This is due to a number of reasons, including: Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence.

Common causes of foaming are excessive solids or alkalinity, and the presence of organic matter such as oil. Keeping dissolved solids below the concentration that causes foaming requires continuous or periodic blowdown of the boiler. High boiler water alkalinity increases the potential for foaming, particularly in the presence of suspended matter.
