A total of 225 coal samples and 106 printouts of coal analyses were provided on request to the coal research community. The relationship between reflectance and coal rank was evaluated using 885 coals from the Penn State Coal Data Base. Reflectance distributions showed that coals of medium volatile bituminous rank and higher could be discriminated using mean maximum reflectance. A set of 21
coals to determine the relation of the rate of burning of pulverized fuels and of the radiation from their flames, to the type of coal and the fineness of pulverization. The principal conclusions drawn from the results of this investigation are: That fineness of grinding becomes in creasingly important as the com bustion space is restricted; that the type of coal influences the rate of ...
pulverization: (pŭl″vĕrīzā′shŭn) [L. pulvis, powder] The crushing of any substance to powder or tiny particles.

illustrates that the mean particle size for 7445 µm coal sample was decreased from µm to µm with the increase of ultrasonic time from 0 to 120 min, while the volume percentage of 45 µm coal particles was increased from % to %. The greatest pulverization effect was obtained when ultrasonic time was 120 min, and the particle size distribution was hardly changed with ...
