Milling and drying experiments of low quality lignite containing high moisture and ash content in IFK´s fan beater mill facility Small (20 kW th ) and large (500 kW th ) technical scale co-firing tests of pre-dried lignite & hard coal in different thermal shares to assess emission behavior, slagging and fouling, burnout and fly ash quality.
Mill air flow variations result in changes in mill outlet temperature and fineness as well as capacity. Ball tube mill. Ball tube mills are either pressurized or suction type. In the pressurized type, the hot primary air is used for drying the coal and to transport the milled coal …
Therefore, lignite needs to be dried be-fore being ignited to ensure a good ignition and burnout behavior in pulverized coal-fired units. The drying is combined with the grinding process in special milling equipment, the beater wheel mill. But, the drying process cost extra energy and reduce the efficiency of lignite-fired power generation units.
