  2. 1. Rapid measurements of the moisture content in biofuel

    Author : Jenny Nyström; Erik Dahlquist; Stefan Backa; Eva Thorin; Bo Franzon; Clarke Topp; Mälardalens högskola; []
    Keywords : radiofrequency measurement; moisture content measurement; fuel characterization; biofuel; time domain measurement; Bulk measurement; Multivariate data analysis;

    Abstract : An increasing number of power plants in Scandinavia are beginning to use biofuel instead of coal or oil. The material in the new fuel is a mixture of woodchips, mostly Pine, Spruce and Salix, bark, GROT (tops and branches from felling waste) and sawdust from sawmills. It is heterogeneous, having a moisture content varying from 15% up to 65%. READ MORE

  4. 2. Modelling the Moisture Content of Multi-Ply Paperboard in the Paper Machine Drying Section

    Author : Christelle Gaillemard; Anders Lindquist; ALf Isaksson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drying section modelling; multi-ply paperboard; moisture content; identification; grey-box modelling; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : This thesis presents a grey-box model of the temperature and moisture content for each layer of the multi-ply paperboard inside the drying section of a paper mill. The distribution of the moisture inside the board is an important variable for the board quality, but is unfortunately not measured on-line. READ MORE

  5. 3. Bioenergy from Swedish forests : A Study of extraction methods, quality and effects for forest owners

    Author : Daniel Nilsson; Johan Bergh; Peter Lerman; Gudmund Vollbrecht; Nasko Terziew; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; logging residues; forest fuels; moisture content; needles; nutrients; moisture content measurements; Norway spruce; dry-stacking; fresh-stacking; Forestry and Wood Technology; Skog och träteknik;

    Abstract : The forest constitutes a very important element of renewable natural resources and makes a significant contribution to the Swedish bioeconomy. Biofuels are Sweden’s largest source of energy; of all the energy we use, 32% comes from biofuels, and of this approximately 85% comes from the forest and the forestry sector. READ MORE

  6. 4. Moisture content measurement in the wood industry

    Author : Tommy Vikberg; Björn Källander; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Abstract : In the wood industry, determination of the moisture content (mc) with a highaccuracy is of great importance. The green mc is important for optimisation of thewood drying process at sawmills, whereas the mc of dried boards is of interest for thefurther processing and final use of the boards. READ MORE
