Types Of Pulverised Coal Firing System Brainkart

pulverised coal firing is done by two systems: unit system or direct system. ii) bin or central system unit system: In this system, the raw coal from the coal bunker drops on to the feeder. hot air is passed through coal in the factor to dry the coal. the coal is then transferred to the pulverising mill where it is pulverised.

the gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. this ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.
