Turning Eureka into Results EPRI Journal

Turning Eureka into Results EPRI Journal

Nov 09, 2015 路 With DryFining, lignite coal is dried by power plant waste heat and moved by enclosed conveyor belts. It鈥檚 a fluidized bed drying process: the solid lignite particles are percolated through a dryer using heated air to vaporize some of the fuel moisture. This produces a higher quality fuel with increased energy density and fewer contaminants.
