High-Pressure Boiler Inspection Procedures (with Checklist
For boiler feed water (the water actually being heated or boiled), of course the pH is important. If that is too acidic, it can cause corrosion of the internal surfaces within the boiler, which is a big problem. But I'm talking about condensation from the boiler exhaust, which is generated by fuel combustion.

Oct 31, 2016 · Condensate from condensing boilers is acidic and corrosive to many materials and should be treated to maintain a pH of no less than 5 before disposal. There can be a wide variation of the pH of condensate from condensing appliances due to the chemical make-up of the gas being combusted or from the way in which the appliance is operating in a particular application.
All internal surfaces are exposed and cleaned prior to the boiler inspection. 8-Frequently, the boiler inspector requires all of the plugs removed at the water column and the low water fuel cutoff controls opened so the inside float chamber can be inspected. Fusible plugs must be replaced. After both the fire side and water side of the boiler have been cleaned, notify the inspector that the boiler is ready for inspection.
Feb 19, 2017 · in THE MAIN WALL. Regarding the condensate produced in Condensing Boilers, I understand that the pH is low making the condensate acidic and therefore corrosive. A Neutralizer (limestone) is supposed to help raise the level of the pH. However, I am reading discussions, in other forums, call the general make-up of this condensate, Nitric Acid (a strong acid-pH 1-3), while others say it is, Carbonic Acid (a weaker acid
Jan 02, 2020 · Yes, even if you don't have to use one. Typical condensate from a condensing boiler has a pH level of 3.2 to 4.5, which is acidic enough to leave stains, kill shrubs, and eat away cast iron drainage systems. So remember to include a condensate neutralizer when designing a system. Correspondingly, how long does a condensate neutralizer last?
