Soot Blowers The fuel used in thermal power plants causes soot and this is deposited on the boiler tubes, economizer tubes, air pre heaters, etc. This drastically reduces the amount of heat transfer of the heat exchangers. Soot blowers control the formation of soot and reduce its corrosive effects.

Dissolved oxygen corrosion

Even this small amount of oxygen is corrosive at boiler system temperatures and pressures. Removal of the last traces of oxygen is accomplished by treating the water with a reducing agent that serves as an oxygen scavenger. Hydrazine and sulfite have been widely used for this purpose, but they have some shortcomings.
