Numerical results from the model, compared to data from a pilot scale lignite dryer located at Great River Energy's Coal Creek Station, show good agreement. The dryer model was used to perform parametric calculations on the effects of dryer design and operating conditions on dryer performance and required in-bed heat transfer.

Then, a trough solar collector is installed to generate thermal oil (140 °C) for lignite sufficient drying in the depth dryer, producing the final dried coal. The drying equipment employed is WTA dryer in which coal is fluidised by air, and the drying fluids release the heat inside the exchanger [15]. After two-stage drying, the coal flows ...

Methods of the drying of the lignite coals can be broadly divided into two groups. In the first group, the method of drying is known as evaporative drying. In the evaporative drying of the coal, the heat is provided to remove the water from the coal particle. The drying medium can be air, flue gas, or superheated steam.
