Aug 19, 2015 Abstract Fanimpact mills are commonly applied in the grinding and dilute-pneumatic transportation of lignite or brown coals with high moisture contents to the furnaces in large steam boilers. Each of the two to eight mills feeds pulverized coal into two or more burner nozzles. An online detection of the pulverized-coal mass flow distribution among the burners is vital for the control of the ...

The Impact of Predried Lignite Cofiring With Hard Coal in

The Impact Of Predried Lignite Cofiring With Hard Coal In

Tests on the boiler were performed during low load operation and the lignite share reached over to 36 by mass. The predried lignite, kept in dedicated separate bunkers, was mixed with bituminous coal just before the coal mills. Computational fluid dynamic CFD simulation of a cofiring scenario of lignite with hard coal was also performed.
