Comparing air to steam fluidized bed drying, the relative drying ratios for a similar conditions (such as 130170 °C) remains consistent, with the exception of particle size. The resultant 130 °C dried coal was used to analyze the moisture readsorption properties of the coals. The data show that steam fluidized-bed dried coals readsorb less
