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 of tube failures. It typically improves the stability of boiler chemistry.
For high steam usage boilers or very low returned condensate boiler systems, generally a 3 or 4 drums chemical program is used. For lower steam usage boiler systems, a 1 to 2 drum boiler chemical program may be used to reduce the number of chemical drums onsite. This program is referred to as an All in One chemical.
Chemicals used to treat steam boiler systems are applied based upon the demand and mode of reaction of each chemical used. The theoretical versus actual consumption and the ease of control of these chemicals can vary according to many factors specific to each application.

The boiler might require either a mechanical or chemical cleaning. The deaerator vessel and internals should be inspected on a regular basis for signs of corrosion. This check is an important safety issue because a deaerator can rupture from oxygen corrosion damage.
Chemical treatment of water inside the boiler is usually essential and complements external treatment by taking care of any impurities entering the boiler with the feed water (hardness, oxygen, silica, etc.). In many cases external treatment of the water supply is not necessary and the water can be treated only by internal methods.
Chemical feed points are usually selected as far upstream in the boiler water circuit as possible. For chemical feed beyond the feedwater pump or into the steam drum, the pump must be matched to the boiler pressure. For high-pressure boilers, proper pump selection is critical. Product Feed Considerations
Chemical dosing of the boiler feedwater will lead to the presence of suspended solids in the boiler. These will inevitably collect in the bottom of the boiler in the form of sludge, and are removed by a process known as bottom blowdown.
