Abstract: Taking applying air, nitrogen and steam as the fluidizing medium, the optimal drying process parameters of low rank coal fluidized bed were investigated on the basis of drying characteristics, chemical structure change and energy consumption of low rank coal. Combined with microwave drying technology and microwave-assisted fluidized bed technology, a microwave-assisted fluidized bed drying technology was proposed based the low rank coal large-scale upgrading technology. The results show that the microwave-assisted fluidized bed dryer will be available for industrial use. Large scale of microwave cavity design and fluidized bed drying equipment will be taken into account in the future.

Keywords: low rank coal; dry engineering; fluidized bed
