Boiler Feedwater Treatment (Part I): Why Water Treatment is

Boiler water carryover is the contamination of steam with boiler water solids. Common causes of boiler water carryover are: Bubbles or foam form on the surface of the boiler water and leave with the steam. This is due to high concentrations of insoluble or soluble solids in the boiler water.

Explained: How Does a Deaerator Work? - Boiler Water Treatment

Boiler feed water sprayed from top through spray nozzles and it is preheated by steam which is coming from sparger. The purpose of the pre heating is to raise the temperature of feed water to its saturation temp at deaerator operating pressure. The preheated feedwater then flows into the deaeration section, where it is deaerated by the steam

Boiler feedwater - Wikipedia

Boiler water is treated to prevent scaling, corrosion, foaming, and priming. Chemicals are put into boiler water through the chemical feed tank to keep the water within chemical range. These chemicals are mostly oxygen scavengers and phosphates. The boiler water also has frequent blowdowns in order to keep the chloride content down.
