Drying Technologies of Lignite Coals IspatGuru

Fig 2 Schematic overview of the WTA lignite fine drying process. The raw coal is ground down to a size less than 2 mm in two hammer crushers directly connected in series. After the grinding, the coal is fed into the fluidized bed, in which the fluidizing medium is the vapour arising from the drying process. Evaporation of water occurs at 110 deg C under slight over-pressure by heat exchangers

INDIRECT THERMAL DRYING OF LIGNITE: DESIGN

The process aims at the production of dry lignite and clean steam as part of a gasification procedure. Both flighted and bare drum modes have been employed. Temperature profiles along the dryer length, the amount of evaporation (moisture conversion) and the solids residence time distribution (RTD) were measured. A non-isothermal model was tested under three different regimes of solids flow
