| Resumen | Transcripción del resumen del autor. This paper presents the effects of particle size, moisture content, and coal type on the flowability of pulverized coals. A plexiglas hopper for visualizing the coal discharge and a Jenike-type shear apparatus for measuring friction characteristics were used to investigate the flowability. The fine coal displays weaker flowability because of its larger specific surface area and stronger agglomeration in comparison to the relatively large-size pulverized coal. The number of agglomerated particles C0 increases with the decrease in the particle size, which is also confirmed by the scanning electron microscopy (SEM) images. Increasing the moisture content tends to make the pulverized coal more cohesive. Cohesive forces acting among wet coal particles are mainly due to capillary forces associated with liquid bridging, which increases with the moisture content. However, the moisture content to some extent may act as a lubricant and improve flow along the wall surface. The coal type also has a significant effect on the flowability because of the differences in their compositions and physical structures. The measuring results show that the flowability of pulverized coal improves with the increasing coal rank. |
