机译:下级煤的洁净煤生产工艺

摘要

The invention describes an integrated process for the production of clean coals having ash content of below 34%, below 17.5% and below 60% from inferior grade lower seam coals These clean coals with varying ash contents are useful as power coal in thermal power stations( where clean coals are required to meet environmental pollution norms), metallurgical coke making and feedstock for fluid bed boilers respectively.
