Research project: Performance Evaluation and Failure Analysis of Preventive Corrosion/Erosion Coatings Used in Power Plant and Refinery

Abstract

The main objective of the project is to identify, research, simulate, experiment, develop and fabricate a non-corrosive/erosive barrier coating to be applicable for the heat exchanger surfaces in nuclear power plant and refineries.

Tube erosion and corrosion on the heat exchanger surfaces can cause the boiler downtime. It has been reported that the  problem associated with the alkali chloride deposits in biomass-fired boiler. The most severe corrosion problems in biomass-fired systems are expected to occur due to Cl-rich deposits formed on superheated tubes. Reactions between the metallic surface and this species, or other alkali-containing species such as carbonates, have to be avoided to increase the corrosion resistance of the super heaters . However, the phenomena of corrosion or degradation of this case may be complex failure and corrosion mechanism should be extensively studied in order to extend the life time of the tubes in the service atmosphere.
