THE ROLE OF ULTRA-FINE PARTICLE TECHNOLOGY IN CLEAN COAL TECHNOLOGY

From requirement for coal particle size and its distribution incoal benefication technology and effect of liberation on ultra-clean coal and separa-tion of coal macerals,the role of ultra-fine particle technology in clean coal technol-ogy has been discussd. It has been showed that coal particle size and its distributionmake very important role in preparation of coal water slurry and its utilization,coalcombustion, In preparation of ultra-clean coal,the liberation of minerals in coal isexpected. In selective oil agglomeration of ultra-fine coal,with the particle size de-creasing, combustibles recovery and ash rejection increase. For high pure maceral inseparation, it is demanded to liberate well the macerals. But, the preparation of ul-tra-fine coal and its characterization,ultra-fine particle processing thechnology arean area that must be researched,therefore,in clean coal technology,the project relative to ultra-fine particle coal technology mast be considered.
