Combating hot corrosion of boiler tubes - A study

The premature failure of boiler tubes, especially in coal fired boilers poses serious threat to the efficiency of the Indian boilers. In coal fired thermal power plant boilers, hot corrosion and erosion is the primary reason behind downtime, which leads to huge economic losses. So the consolidated results of the various researchers working in the area of combating hot corrosion of boiler tubes, especially in context with Indian boilers (both actual and simulated environment) are presented in this article. These results help the researchers in selecting an appropriate and accurate coating material composition, coating process and parameters for a particular boiler steel to improve the life of boiler tubes. So, that, any unwanted damage of boiler tubes due to hot corrosion could be minimized.
