  • COARSE DRY COAL CLEANING - Energy

    2013-2-21  Dry Coal Cleaning Applications in India Many coals located <1000 km away from the utility are not cleaned. As a result, 40%-45% ash coals are transported and used in utilities designed for 25%-35% ash coal. For a relatively easy-to-clean India coal, dry cleaning has the ability to reduce the ash from 41% to 30%. 0 5 10 15 20 25 30 <1.35 1.35-1 ...

    2016-5-17  Abstract: Dry dense-medium fluidized bed separation provides a new alternative approach for coal beneficiation and cleaning. An indicator of segregation degree Sash was proposed to evaluate the stratified performance of coal samples by bed density. Fluidization stability of the bed was greatly enhanced by mixing a certain amount (21.53%) of fine magnetite powder (< 0.15 mm) into the fluidized media, which indicated a uniform density distribution as well as slight fluctuations in bed. It was found that the favorable density-segregation performance of 3–13 mm coarse coal occurred with a static bed height of 80 mm and a superficial gas velocity of 11.84 cm/s. The optimal segregation degree values of 0.67, 0.74 and 0.76 were obtained for 3–6, 6–10 and 10–13 mm coal samples, respectively. Low-ash clean coal with yields of 50.79, 56.83 and 61.24% were effectively acquired by the dry separation for various coal
