Metallurgical Coal Earth And Atmospheric Sciences

Metallurgical Coal Earth And Atmospheric Sciences

Metallurgical coal is low in ash, sulfur, and moisture, and contains the right amount of hydrocarbons and plasticity. Uses Metallurgical coal is crushed and heated in an airless furnace at high temperatures around 1000 C. The heat drives off the moisture, impurities, and sulfur. Meanwhile, the coal expands, becomes porous and turns into coke.

Spontaneous Combustion Liability Of Coal And Coal

Mar 05, 2019 It was observed that when dry air is transported over wet coal, moisture is removed from the coal, thus causing a decrease in temperature. Although, when misty air enters dry coal, temperature increases due to moisture adsorbed from the air (Akgun and Arisoy 1994a). The wetting and drying of coal particles promote heat exchange within a coal mass.
