  1. 1. Steam Drying of Porous Media

    Författare :Jörgen Hager; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport coefficients; experimental; heat and mass transfer; sorption isobar; packed bed; porous particles; hybrid model; volume average; porous media; superheated steam; steam drying; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : The present study concerns heat and mass transfer in porous media dried by superheated steam. Specifically, the steam drying process of a packed bed of porous particles was studied in order to obtain design data for a band drier. LÄS MER

  3. 2. Superheated Steam Drying of Wood Chips in Pneumatic Conveying Dryers

    Författare :Christian Fyhr; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; superheated steam; drying; pneumatic conveying; convective; non-spherical particles; wood; heat transfer;

    Sammanfattning : This thesis contains a fundamental investigation of a pneumatic conveying dryer. The model presented can be used both for design and rating purposes and, although the main emphasis is put on the drying of wood chips in superheated steam, the results can be used for other systems as well.
