    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

  2. 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

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

    Author : Chao Zheng; Monica Ek; Dongfang Li; Lennart Salmén; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; 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.

  4. 4. Wood Fungi and Forest Fire

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

    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

  5. 5. Phenolic Antioxidants in Wood Smoke

    Author : Jennica Kjällstrand; Chalmers University of Technology; []
    Keywords : smoke; benzene; methoxyphenols; antioxidants; wood; lignin; combustion; biomass;

    Abstract : Smoke from residential wood burning constitutes a complex mixture of organic compounds with varying environmental and health effects. This thesis focuses on antioxidants and aromatic hydrocarbons emitted from small-scale burning. READ MORE
