2. 1. Fighting flameless fires : Initiating and extinguishing self-sustainedsmoldering fires in wood pellets

   Author : Ragni Fjellgaard Mikalsen; Vidar Frette; Bjarne C. Hagen; Ulrich Krause; Anne Steen-Hansen; Ulrich Krause; Nieves Fernandez-Anez; RISE; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel storage safety; Industrial fire; Biofuels; Smoldering; Extinguishment; Fire suppression; Fire growth; Fire spread; Heat transfer; Nonlinear dynamics; Complex systems; Combustion; Biomass energy; Synchronization; Oscillations; EMRIS;

   Abstract : Smoldering fires represent domestic, environmental and industrial hazards. This flameless form of combustion is more easily initiated than flaming, and is also more persistent and difficult to extinguish. The growing demand for non-fossil fuels has increased the use of solid biofuels such as biomass. READ MORE

4. 2. Reaction to fire performance of wood and other building products

   Author : Lazaros Tsantaridis; KTH; []
   Keywords : building products; charring of wood; cone calorimeter; fire retardant treated wood; fire tests; ignitability; mass loss; rate of heat release;

   Abstract : The theme of this thesis is the reaction to fire performanceof wood and other building products, andparticularly thematerial fire properties time to ignition, rate of heat releaseand smoke production. These properties have been measured by asmall-scale fire test method, the Cone Calorimeter, andpresented for different types of building products. READ MORE

5. 3. Cellulosic Thermal Insulation with Improved Water Resistance and Fire Retardancy

   Author : Chao Zheng; Monica Ek; Dongfang Li; Lennart Salmén; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Bio-based; Cellulosic; Fire retardant; Thermal insulation; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : Sweden is one of the largest countries by area in Europe, and almost 70% of it is covered by forest. These abundant forest resources benefit the Swedish bioeconomy, but the pulp and paper industry is facing the challenge of a decrease in the demand for printing paper due to a significant shift to electronic media; therefore, it is a priority to use pulp to produce alternative value-added products, such as thermal insulating materials in buildings.

6. 4. The effect of wood properties on oxidative isolation of cellulose nanofibrils and characterization of networks

   Author : Simon Jonasson; Kristiina Oksman; Lars Wågberg; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose nanofibrils; wood; TEMPO-oxidation; nanofibril network; lignin; tension wood; transgenic tree; Trä och bionanokompositer; Wood and Bionanocomposites;

   Abstract : Wood is a natural resource that has been an integral part of society for as long as humans have been on Earth. From serving as fuel for fire and construction material the applications of wood has been developed in modern times and only surged as a consequence of societal strive for sustainability and usage of green resources.

7. 5. Wood Fungi and Forest Fire

   Author : Fredrik Carlsson; Bengt-Gunnar Jonsson; Mattias Edman; Svante Holm; Jacob Heilmann-Clausen; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Forest fires have been the major stand-replacing/modifying disturbance in boreal forests. To adapt to fire disturbance, different strategies have evolved. This thesis focuses on wood fungi, and the effect of forest fire on this organism group. READ MORE
