Abstract
A coal upgrade plant includes: a dryer 1 that dries coal; a pyrolyzer 3 that pyrolyzes the coal dried by the dryer 1; a quencher 5 that cools the coal pyrolyzed by the pyrolyzer 3; a finisher 7 that deactivates the coal cooled by the quencher 5; and cyclones 28 and 94 that collect pulverized coal generated from the coal, wherein the pulverized coal collected by the cyclones 28 and 94 is fed to an absorber fed to a scrubber 32 that treats a flue gas. Thus, the mercury generated from the coal upgrade plant can be removed.
