carbonic acid in exhaust area
Neighbor has a boiler for radiant heat and the inside of the boil and exhaust has a build-up of carbonic acid. What is the best way to naturalize this crystal. Insufficent heat has caused this and the problem is fixed except for the residual carbonic acid powder and coating all over the place. Need to clean the boil surface.
How do you know it is
Carbonic Acid? Any thing getting back into the combustion chamber is a problem that needs addressed by taking the unit apart and cleaning the inside of the chamber and flue passages. What is the Make and Model of the boiler? That will help to identify exactly how to go about the cleaning process. I would also recommend a combusstion analysis be done.
Call manufacturer
Tell your neighbor to find old manuals and read troubleshooting section. If this doesn't helps, he needs to call manufacturer. Not mentioned how old is the unit. But be sure not to suggest anything that voids the warranty. You'll be the one to blame later.
Carbonic acid crystal???
Carbonic acid (H2CO3 for chemists), composed of a molecule of water and one of carbon dioxide, does not form crystals, but exists only in solution (typically) with water. If you warm it up, it separates into water vapor and carbon dioxide gas. So your neighbor may be finding crystals, but they will not be carbonic acid.
