Retrofitting lignite plants: considering the options ...

Jun 11, 2016  Lignite beneficiation has been extensively investigated and, currently, fluidised bed pre-drying utilising low-grade heat streams is the most promising technique. Established plants in Germany (RWE/WTA) and the USA (GRE/DryFiningTM) show efficiency gains of several percent dependent on the degree of dryer integration.
