Pulverized coal produces about 50% of the world’s electric supply. The concept of burning coal that has been pulverized into a fine powder stems from the belief that if the coal is made fine enough, it will burn almost as easily and efficiently as a gas.

Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an airgas mixture, pulverized coal can be introduced directly into the boiler for combustion. There are several pieces of equipment involved in processing coal to be burned in this fashion.

2018-10-2 and the pulverized coal is lifted to a powder separator by another bucket elevator. The powder separator consists of a centrifugal rotor, 6 cyclones and a self-recycling pneumatic system. Large size particles return to the mill, and fine powder is collected by cyclones and then deposits at the bottom hopper of the separator.

Read More2021-3-12 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.

2021-3-12 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 ...
