Coal storage system and coal storage method

摘要

The present invention provides a coal storage system and a coal storage method that achieve appropriate temperature control at low cost without significantly increasing the water content of coal. The coal storage system comprises a coal yard 2 for storing coal, a pyramid-shaped coal pile 1 having a ceiling surface 11 and an outer peripheral side surface 12 formed in a coal yard, a pressure buildup equipment for expanding the coal pile 1, And a sprinkler 3 for sprinkling coal pile. At least the outer peripheral portion of the ceiling surface 11 of the coal pile 1 is pressurized by the pressure-reducing equipment and the outer peripheral side surface 12 is sprinkled by the sprinkler 3.
