METHOD AND APPARATUS FOR DRYING LOW GRADE COAL |
摘要 |
<p>Low-rank coals, such as lignite, are dried by evaporating interstitial water therefrom in a superheated steam flow countercurrently passed through a sealed rotary cylindrical vessel. A composite steam discharged from the vessel is partially condensed to remove an amount of water therefrom substantially equal to the amount of water removed from the coal, with a resultant flow of residual steam reheated and returned to the cylindrical vessel for further drying of low-rank coal.</p> |
