Coal Crushing And Washing Process

The major emission source in the fine or coarse coal processing phases is the air exhaust fromthe air separation processes (air tables). For the dry cleaning process, these emissions are generatedwhen the coal is stratified by pulses of air. Particulate matter emissions from this source are normallycontrolled with cyclones followed by fabric filters. Potential emissions from wet cleaning processesare very low
