Operation of Boiler and Conductivity in Drum Water

To prevent corrosion of boiler heat transfer surface in evaporator, superheaters, reheaters, and turbine, the quality of feedwater and boiler drum water are chemically controlled. Boiler outage due to tube failures is the main concern and generally this causes long term over heating failure due to deposits. Many methods of chemical control are
