pH Treatment | CleanBoiler.org - Boiler Consortium
pH Treatment. Introduction. A pH less than 7 is acidic, and a pH greater than 7 is basic (alkaline). Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6. Boiler Efficiency; Steam Basics;

> Natural water is usually between 6.5 and 7.5 pH. A common recommendation is to maintain boiler water at 8.5 pH.Acidic water is corrosive. Alkalinic water is more prone to scaling.Alkalinity is a measure of the bicarbonate (HCO3), carbonate (CO3

Chemical reactions happen very fast at elevated temperatures. Because of this we try to operate the boiler at the lowest possible corrosivity relative to pH (Note: this is only for boiler operating without high purity feedwater). That point is aro

Vaporous carryover depends on pressure and on boiler water chemistry. It is not affected by boiler design. (6.9 MPa). Vaporous silica carryover at a pH of 10.0 is 88% of that at a pH of 8.8. The vaporous silica carryover at a pH of 11.0 is 74% of that at 8.8. Carryover of impurities from boiler water to steam is also inherent to boiler

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure…

Increase the firing rate and gradually raise the boiler pressure. 1. When reheater outlet pressure reaches 4.0 MPa or to a value recommended by the steam generator manufacturer, gagging devices may be provided to all safety valves on hot reheat and cold reheat pipe lines barring the lowest pressure safety valve on hot reheat pipe lines; 2.
