One of the foremost concern in thermal power plants is the formation of deposits of corrosion products
in diverse areas of the water/ steam cycle. This deposition process causes local overheating and rupture
of boiler tubes, damages of turbines and other segments of power units, that ultimately leads to sizable
efficiency loss. The corrosion products are metal oxides usually present in colloidal form and tend to
precipitate on the heat exchange surfaces. In this paper a new approach to prevention deposit using
electrokinetic properties of colloidal particles is discussed. The mechanism of deposition formation is
outlined considering the role of electrostatic interactions between the steel wall surface and colloidal
particles. Furthermore, utilization of zeta potential data in deposit predicting and control is thoroughly
elucidated. It was inferred that described concept is applicable in power industry through changing
electrokinetic potential of colloidal particle what is atta...inable either by modification of structure of
adsorption layer of metal oxide particles or by altering pH of boiler water. It was stated that exploiting
surface properties of corrosion product for controlling and mitigation deposition in power chemistry
circuits may have a huge benefit for power plants improving their availability, reliability and
performances.
