摘要： A process for thermally upgrading coal in a vertical processor wherein the coal is gravity fed and a heated inert gas is introduced into the processor. The temperature of the gas, the size of the coal and the rate of movement of the coal are controlled to efficiently remove moisture from the coal and to not remove volatile organic compound.

摘要： An apparatus for upgrading coal comprising a baffle tower, inlet and exhaust plenums, and one or more cooling augers. The baffle tower comprises a plurality of alternating rows of inverted v-shaped inlet and outlet baffles. The inlet and outlet plenums are affixed to side walls of the baffle tower. Process gas enters the baffle tower from the inlet plenum via baffle holes in the side wall and dries the coal in the baffle tower. Process exhaust gas exits the baffle tower into the exhaust plenum via baffle holes in a different side wall of the baffle tower. Coal that enters the baffle tower descends by gravity downward through the baffle tower and enters a cooling auger, where the dried coal from the baffle tower is mixed with non-dried coal. A method of using the apparatus described above to upgrade coal.

摘要： The invention described is a process for improving the performance of a commercial coal or lignite fired boiler system by supplementing its normal coal supply with a controlled quantity of thermally beneficiated low rank coal, (TBLRC). This supplemental TBLRC can be delivered either to the solid fuel mill (pulverizer) or directly to the coal burner feed pipe. Specific benefits are supplied based on knowledge of equipment types that may be employed on a commercial scale to complete the process. The thermally beneficiated low rank coal can be delivered along with regular coal or intermittently with regular coal as the needs require.

摘要： An apparatus for heating low rank coal having a processor with transverse baffles. Coal is introduced into the top of the processor and passes through the processor by gravity. Heated relatively inert gas is introduced into the processor and flows through the coal, heating the coal and removing moisture from the coal. The temperature of the heated process gas, the size of the coal, the size of the inlet and outlet openings of the processor and the rate of flow of the coal are selected for optimum efficiency.
