Heat transfer between a surface and an infiltrated bed of solid particles

Energy-efficient fluidized bed drying of low-rank coal

“…(13) The drying was performed under atmospheric conditions, with the assumption of no heat loss from the drying system to the surroundings. (14) The LRC particles size was assumed to be constant during the drying process. The pressure loss in the fluidized bed includes the pressure drops across the bed, Δp bed, and bubble cap distributor, Δp d , respectively.…”

“…The heat transfer coefficient relative to the horizontal heat exchange tubes immersed in the fluidized bed, a t , was calculated using [13,14] Nu t ¼ 0:74 Ar 0:1 ρ s ρ g ! 0:14 C ps C pg 0:24 υ s 2 = 3 þ 0:46 Re Pr…”
