  2. 1. Drying and Pyrolysis of Logs of Wood

    Author : Jenny Larfeldt; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; structural changes; heat transfer properties; pyrolysis; drying; single particle; wood;

    Abstract : This work concerns log firing in small-scale boilers for house heating, which in Sweden meets a heat demand of 12 TWh a year. In boilers used for domestic central heating in the sizes of 10 to 30 kW the predominant combustion technique is grate firing. READ MORE

    Abstract : The trends in waste electrical and electronic equipment (WEEE) generation shows that their volume constantly increases, while the current waste management technologies have proven to be insufficient in order to meet the strict criteria and the new legislations of the European Union. Pyrolysis and thermal treatment in general could be a valuable solution for closing the loop of materials and could contribute to the energy demands of modern society. READ MORE
