  • Computational model for microstructure and effective

    The ash deposits formed in pulverized-coal fired power plants reduce heat transfer rate to furnace wall, super heater tubes, and other heat transfer surfaces. The thermal properties that influence strongly on this heat transfer depend mainly on the microstructure of the ash deposit. This dissertation examines three issues associated with the ash deposits in utility boilers: (1) the …Get Price
