Thermal Characterization of Coal Ash Powders: Heat Capacities and Minimum Sintering Temperatures
Published online by Cambridge University Press: 25 February 2011
Abstract
Ashed mineral matter from ground coals were prepared by combustion at 973 K. Five coal samples ranging in rank from lignitic to high-volatile bituminous coals were used as starting materials. The heat capacities of the coal ash materials were measured between 140 K and 900 K by differential scanning calorimetry. The minimum sintering temperatures of each of the ash powders were determined using a high temperature dilatometer.
