  • WTA technology for drying of lignite coal – IspatGuru

     · Grain size of the raw lignite coal. WTA drying process has been developed for two input grain sizes namely (i) the coarse grain size (0 mm to 6 mm), and (ii) the fine grain size (0 mm to 2 mm). The coarse grain size alternative is used if the downstream process needs dry lignite coal of a minimum grain size, such as gasifiion in the high temperature Winkler .
