Abstract (en)
[origin: US4382777A] The present invention relates to a process for modifying the properties of a swelling coal, to an installation for carrying out the process and to a chamber for treatment by fluidization and crushing. A percussion-type crusher is installed in a fluidization chamber at about 1 meter above the zone of connection between a duct for conveying coal by pneumatic transport and the chamber. A combustion chamber produces gases for transport and fluidization, having an oxygen content of at least 10%.
