How to remove the inherent moisture in coal
Thread Content
Coal moisture includes inherent moisture, external moisture, and bound moisture. How to remove internal moisture.
Internal moisture generally cannot be removed through physical processes; unless it is moisture bound by weak chemical bonds such as crystalline water, the water can only be removed through chemical reactions, and coal also undergoes chemical reactions during this process!
Firstly, water in coal exists in two forms: free water and bound water, with bound water referring to crystalline water. External water can generally be removed at 100 degrees Celsius, while internal water usually requires 200 degrees Celsius or even over 500 degrees Celsius to be removed!
