This firing method is normally used for anthracite. Mills. In a PF boiler system, coal is pulverised to typically 7075%, passing 75 micron and entrained in preheated primary air for conveying to the burners. In some smallscale operations indirect firingis used, this is when the pulverised coal is stored in a bin before feeding to the burners.
