A Comparison of Three Types of Coal Pulverizers Babcock Power
The ATRITA pulverizer is a highspeed, compactly designed machine which reduces raw coal to pulverized coal by the combination of crushing, impact and attrition The AT RITA has Today's coalfired utility boiler operation needs pulverizer designs to supply pulverized coal with required throughput and coal fineness, and also perform with lower specific power Coal Pulverizer Design Upgrades to Meet the Demands of Low Coal Pulverizer are designed to reduce the size of the incoming raw coal to a fineness that will result in good furnace performance The grinding surface in the pulverizer resembles a shallow dish or bowl Therefore the name “Bowl Mill” Bowl Mill Coal Pulverizer COAL HANDLING PLANTSsupplying pulverized coal to one of the three horizontal rows of (4) dualfuel burners When operating at boiler MCR, each mill had a coal throughput of approximately 53,000 #ffir Specified product fineness was 70% thru 200 mesh and 98% thru 50 mesh Diminishing supply of the original Kansas coal forced OPPD to gradually transfer in 197576WorldProven Coal Pulverizer Technology Debuts in the US
