Investigation of a Gas-Solid Fluidized Bed for Lump Coal Separation

Abstract:

The influences of operating parameters (bed height, air flow rate, and separation time) on the separation effect for lump coal were experimentally studied. The results show that shallow bed takes less time to reach steady separation state comparing with the deep bed. Increasing separation time at low air flow rate and decreasing separation time at high air flow rate could improve the separation effect. Separation effect could get the optimal under the condensation of bed height at 90mm, air flow rate at 8m³/h and separation time at 60s.
