The objective of a chemical cleaning is to safely remove all the deposits from the inside of the boiler tubes. In low-pressure boilers, chemical cleaning typically removes calcium carbonate and other hard adherent scales. In higher-pressure boilers, the major deposit removed is magnetite and some copper. Chemical cleaning can improve the boiler heat rate and reduce the number …Learn More
