There are distinct types of boilers, such as fire tube boilers, water tube boilers, pulverized fuel boilers, grate furnace boiler, oil and gas-fired boilers, fluidized bed combustion boilers, and waste heat boilers. These boilers are employed in distinct industries such as chemical, fertilizer, refinery, cement, textile, pharmaceutical, steel, sugar, pulp and paper, food, and thermal power plants. But these boilers are subjected to various types of failures and pose a severe threat to the efficiency of the plant/industries. Hence, this manuscript aims to provide an overview of various causes of boiler failures, including caustic embrittlement, oxygen pitting, fouling, agglomeration, hydrogen damage, stress corrosion cracking, slagging, fatigue failure, hot corrosion, oxidation, erosion, etc. Finally, various preventive measures, including surface modification techniques, are discussed. So, by developing more advanced coating material combinations and methods/preventive measure, it is possible to improve the qualities of protection for futuristic applications.
