COARSE DRY COAL CLEANING Department of Energy

2013-2-21 · Most India coals have cleaning characteristics that are difficult. The most efficient wet- based coarse cleaning technologies have difficulty in achieving effective ash reduction. Dry deshaling concentrates on the density fractions that are easy to remove. Using deshaling, ash reduction for a difficult coal could be from 45% to 34%.

Cleaning of coarse and small coal ScienceDirect

2013-1-1 · Methods for cleaning coal particles greater than 1.0 mm in size are discussed. Water-based technologies include jigs, dense (heavy) medium baths and cyclones, fluidised beds and Reflux Classifiers (RC). Dry-based methods include air jigs, air-fluidised beds and tables and optical/X-ray sorting. Likely future trends in plant design are discussed.

11.10 Coal Cleaning US EPA

2015-9-10 · The major emission source in the fine or coarse coal processing phases is the air exhaust from the air separation processes (air tables). For the dry cleaning process, these emissions are generated when the coal is stratified by pulses of air. Particulate matter emissions from this source are normally controlled with cyclones followed by fabric filters.
