coal drying by steam coil

  • Lignite dryingKraftwerk Forschung

    Pre-drying of raw coal has the potential to increase efficiencies by up to 10 for plants that burn moist lignite with a water content of over 45 . Two processes for external coal drying are currently being developed. The first is a mechanical-thermal drying process that mechanically dries raw coal that has been heated to around 140 to 200 °C.
