Abstract

본 발명은 코크스로에 장입된 석탄(C)을 효율적으로 건조시켜서 수분함유율이 적은 건조탄을 얻을 수 있음과 동시에, 이 건조탕 중 미세분말성분을 확실하게 분급해서 제거하여 그 잔류율을 1% 이하로까지 저감할 수 있는 유동층을 이용한 석탄의 건조분급장치에 관한 것으로써, 본 발명은 분산판(2)에 배설된 노즐(21)로부터 석탄(C)의 이송방향으로 분산판(2)에 대해 상부방향으로 경사지게 기체를 분출시키고, 석탄(C)을 유동시키면서 이송하는 유동층(3)을 구비하고, 이 유동층(3)은 석탄(C) 이송방향을 향해서 제1유동층부(8)의 제2유동층부(9)가 연속적으로 구성되어 있다. 이 제2유동층부(9)에 있어서의 기체의 분출속도가 제1유동층부(8)에 있어서의 기체의 분출속도보다 크며, 또 60~80m/sec의 범위내로 설정되어 있다. 또, 유동층(3)의 배출부(6)에는 세로형 충전층(24)이 형성되어 있다.
