1. 1. 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.

3. 2. Multivariable control of a pneumatic conveying system

   Författare :Wolfgang Birk; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Sammanfattning : This licentiate thesis deals with a multivariable controller of a pneumatic conveying system. The industrial process used to illustrate design, analysis and implementation of a multivariable controller is the injection of fine coal into a blast furnace. LÄS MER

4. 3. Heat and Mass Transfer Effects in a U-Bend in Pneumatic Drying

   Författare :Muslikhin Hidayat; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Pneumatic conveying drying is a widely used process in many engineering applications. Due to the high velocity of the drying medium and the limited conveying distance, the drying times of theses dryers are typically short, in the order of seconds. LÄS MER
