  • Coal-Water-Slurries - an overview | ScienceDirect Topics

    The coal-water slurry (CWS) is a potential new form of fuel for application in power boilers and industrial furnaces. The single suspended coal-water slurry droplets have been burned in hot gas streams to reveal their basic nature of evaporation and heating processes. Temperature measurement and microscopic observation are performed.
