Apr 29, 2020 · Proper boiler water treatment eliminates sludge and scale deposits within the boiler. However, over along period of time a film of copper and iron oxides build up on the tube surface. Most of these oxides are transported from oxides of corrosion within the feed system to the boiler with the condensate.Get Price
Feed water composition. In order to generate steam on a constant basis, boiler should be continuously supplied with water, called as feed water. Feed water consists of condensate, which gets collected after the steam gets condensed by losing heat to the process or radiation losses, flash steam and make up water.Get Price
