Minimum fluidization velocities of wet coal particles

Minimum fluidization velocities of wet lignite coal beds were measured. The experiments were carried out in an 8.5 x 10/sup -2/ m i.d. column with particles of average size ranging from 0.15 x 10/sup -3/ to 4.25 x 10/sup -3/m, using air as a fluidizing gas. The experimental results were compared to the values predicted by commonly used correlations. On the basis of data obtained, a simple correction factor was derived. The factor makes it possible to calculate the minimum fluidization velocities of wet coal from equations, originally developed for dry beds if relative moisture content of the bed and average particle diameter are known. Good agreement with experimental data has been found in all cases.
