coal firing using magnetic separator removing iron

Methods of Firing Steam Boiler | Electrical4U

The coal is crushed to 2.5 cm. or less. Then this crushed coal is passed through a magnetic separator to separate any iron content from the coal. Iron must be removed, otherwise during pulverizing iron particles will cause spark which results in unwanted fire hazard. After that, crushed coal is dried properly before pulverization.
