Coal cleaning in a Mag-Mill

Preliminary results obtained in earlier studies have established the technical feasibility of preparing low ash and low sulfur coals by employing dry magnetic separation to treat the internal circulation of air-swept pulverizers preparing pc grind coal for direct firing. The authors now report results of more recent experiments which extend the earlier work. The new studies have tested the effects of treating more of the mill`s internal circulation than was previously possible. The ParaTrap magnetic separator can be retrofitted to existing pulverizers keeping capital costs low. A preliminary engineering evaluation indicates that a 1,600 MW{sub e} power plant burning washed coal from Northern Appalachia can save as much as $4,000,000 per year by procuring raw coals and cleaning them in the Mag-Mill.
