Deaerator | CleanBoiler.org

Heat Exchange on Boiler Feed Water. Whenever heat can be recovered from another source, feed water is one of the best streams to receive this heat. The higher the temperature of the feed water going to the boiler, the more efficiently the boiler operates. However, any type of migratory deposition can impede the heat exchange process.
