1. Thermal stresses in load-bearing glass-timber components
Abstract : Thermal stresses can arise in glass used in architectonic realisations in buildings as a result of solar irradiation: that is, sunlight. The magnitude of these thermal stresses depends on the temperature conditions in the glass in terms of the temperature differences between warm and cold areas. READ MORE

2. Modeling of Pulverised Wood Flames
Abstract : The aim of the current work was at development and validation of modeling tools for simulation of pulverised wood flames in furnaces and study how different factors influence on such flames. The numerical model involves different sub-models for the physo-chemical processes, such as, two-phase flow motion, drying, devolatilization and shrinkage of particles, the formation and oxidation of volatile, tar and char, turbulence-chemistry interaction, turbulence-radiation interaction, etc. READ MORE

3. Acid-catalyzed Liquefaction of Industrial Side-streams for Producing Wood Adhesives and Particleboard
Abstract : Big quantities of residues and side-streams are generated annually from forest-based and agricultural industries all around the world and present a relatively unexplored renewable resource. Due to the absence of a regularly updated and systematic database of supply, industrial residues and side-streams usually end up in landfill disposal, are used for energy generation, or remain at the production sites.

4. Properties of solid wood : responses to drying and heat treatment
Abstract : The hygro-thermal processes that wood is exposed to during drying and heat treatment lead to different reactions or responses in the wood material. The objective of this thesis has been to study the impact of different drying and heat-treatment strategies on various responses, such as strength, sorption/desorption behaviour, dimensional stability and colour changes.

5. Drying and Pyrolysis of Logs of 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
