Drying of coal in steam offers, besides reduction of ยฎre and explosion hazards, improved thermal efยฎciency. In addition, steam-dried coals appear to be less prone to spontaneous combustion. In a previous paper, a mathematical model was developed for the drying of a single porous particle in steam. I

a sludge, onto coal surface. Treatment of coal may also be carried out by oxidation of Fe*+ in the wastewater to Fe3+ prior to addition of the crushed coal, followed by increase of pH to 2-5 for deposition of Fe (III) compound onto coal surface. Gas oil is obtained at high yield in gasification of coal, manufacture of tar, char, etc.

## Abstract A model is developed to determine an optimum apparatus geometry and, for given apparatus dimensions, a financially optimal fluidized bed height. The parameters that effect the operating costs are the bed mass, the apparatus diameter and the gas mass flow rate. To implement such cost opt

The results of drying tests in a fluidized bed and a tray dryer are reported for typical tablet granulations. The data are analyzed to give estimates of total drying times, rates of dryin and overall heat transfer coefficients in each unit. It is concluded that fluidized f e d drying of tablet granu
