Accordingly, coal is usually stored for a long time in a coal storage yard before it is transferred to the furnace for combustion or burning. Conventional coal stockpiles have a large scale and are located in a coal storage yard for several months. In the open air, the coal stockpile is exposed to air and coal is oxidized slowly by oxygen.
