Thermokinetics of Brown Coal during a Fluidized Drying Process

The drying of brown coal in a fluidized bed installation is a typical example of a non-stationary process. In a fluidized bed, the solid particles of coal are exposed to air at a given temperature. Then, the moisture contained in it is discharged into the heating air. This process lasts as long as the moisture content of the material is in balance with the temperature and moisture content of ...

Thermal Coal Drying and Beneficiation Systems

Vibrating fluid bed thermal dryers are typically used for coals with a larger size fraction (such as run-of-mine coal). Vibration significantly assists in the fluidization of sticky and/or wet coals, and helps convey larger particles that may not fluidize well and tend to settle to the bottom of the bed.

Fluidized bed - Wikipedia

Fluidized beds are also used for efficient bulk drying of materials. Fluidized bed technology in dryers increases efficiency by allowing for the entire surface of the drying material to be suspended and therefore exposed to the air. This process can also be combined with heating or cooling, if necessary, according to the specifications of the application. History. In 1922, Fritz Winkler made ...
