Fluidized bed coal drying system

The gas temperature in the fluidized bed was between 110 and 150 C, while the exhaust gas were released with about 100 C. Dry coal samples were taken for analysis at regular time periods. Analyzing the graph from fig. 2, it can be noticed that the water and volatile matter content from the dry coal are lower than in the raw coal, and depend on
