The sorting utilization for low-rank fine coal plays a significant role in upgrading coal resource value and increasing its utilization efficiency.This paper introduced JNWFG furnace,which uses the low-rank fine coal as raw material to produce high quality coal tar and gas as well as stable quality of semi coke.The stable operation of this demonstration plant marks the realization of JNWFG industrial production,which has moved the most critical step for the sorting utilization chain of low-rank fine coal.
