To decrease the downtime and improve life of thermal power plant boilers, a professor at the Indian Institute of Technology Ropar has developed a coating composition that is resistant to both erosion and corrosion.
The coating, developed by Prof Harpreet Singh, has been granted patent for a period of 20 years to make, use and sell it commercially. The coating is presently being explored by General Electric, Bengaluru for final testing in collaboration with IIT Ropar.
Corrosion refers to deterioration of metals caused by oxidation and is one of the major problems faced by thermal plants as it damages boilers, especially the boiler tube system. It is considered to be the root cause of most of the breakdowns in the thermal plants. Read more
