Abstract:
1. An apparatus for upgrading coal comprising: (a) a baffle tower; (b) an inlet plenum; (c) an exhaust plenum; and (d) one or more conveyance devices; wherein the baffle tower comprises one or more side walls; wherein each side wall has an outer face; wherein a portion of the coal enters the baffle tower; wherein the baffle tower comprises a plurality of alternating rows of inverted v-shaped inlet baffles and inverted v-shaped outlet baffles; wherein all of the rows of inlet baffles are parallel to one another, and all of the rows of outlet baffles are parallel to one another; wherein the rows of inlet baffles are perpendicular to the rows of outlet baffles; wherein the inlet plenum is affixed to the outer face of one of the side walls of the baffle tower; wherein the exhaust plenum is affixed to the outer face of one of the side walls of the baffle tower; wherein process gas enters the baffle tower from the inlet plenum via baffle holes in one of the side walls of the baffle tower; wherein the process gas that enters the baffle tower from the inlet plenum dries the coal that enters the baffle tower and becomes process exhaust gas; wherein the process exhaust gas exits the baffle tower into the exhaust plenum via baffle holes in one of the other side walls of the baffle tower; and wherein the coal that enters the baffle tower descends by gravity downward through the baffle tower and enters a conveyance device.
