STEAM/HOT WATER DRYING OF LOW RANK COALS. Conference Paper uri icon

abstract

  • Steam and hot water drying of low-rank coals were carried out at saturated steam pressures between 230 and 330 degree C to study moisture reduction. Moisture reduction increased with temperature and the dried coals did not reabsorb moisture. The heating value was increased upon drying and the sodium content was greatly reduced. Hot water drying produced coal-water slurries that had reduced viscosity and were more stable than those prepared from the original coal. The spontaneous combustion characteristic of these coals was greatly reduced on steam drying.
