Abstract | Frequent load changes or daily shut down and restarting have been imposed on thermal power plants in many areas to fill the gap between the demand for electric power and the variable outputs from renewable energy sources. These operations result in temperature changes in boiler furnaces, and the temperature changes may induce cracks in problematic coal ash deposits, which would contribute to their spontaneous shedding from heat-transfer surfaces. In this work, we microscopically investigated the origin of temperature-change-induced cracks in ash deposits. Analyses of the coal ash clinker generated in a utility boiler indicated that many cracks were generated close to the crystalline SiO |
