Pulverized coal blade feeders “PPL5S” The direct current electric motors with changeable rotation frequency from 1500 to 300 rpm are applied for the output regulation of the feeder The design of pulverized coal feeder provides the even feeding of the pulverized coal over the whole regulation range of output the direct proportion dependence of output from rotation frequency of the blade wheel
For maximum fuel efficiency and low emissions levels you need a precise and consistent coal feed The PFISTER SCF delivers Thanks to the integrated dosing electronics this smart coal feeder provides highly accurate and reliable gravimetric feeding of pulverized fuels to the burning process including coal dust lignite dust and petcoke
Feeders Crushing McLanahan specializes in a variety of crushing solutions to reduce ROM coal to a transportable and marketable top size McLanahan crushers can take the coal producer through all stages of crushing process from initial reduction in the primary stage to further reduction and refinement in the secondary and tertiary stages all while minimizing the generation of dust and fines
The pulverised coal from a mill is transferred through alternative flue gas to the cyclone separator where the coal is separated and flue gas is sent back to the mill The coal is then supplied to the burner feeder from where it is mixed with primary air and supplied to the burner for the combustion
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 Schenck Process LLC ’s gravimetric feeders have become the industry standard in coal fired power
For this reason when raw biomass is fed through the coal feeder for pulverization in a mill designed for coal the output of the mill reduces accordingly If the plant has spare mill capacity it can maintain the thermal input in the furnace but at the expense of additional energy consumption by the mills
