  4. 2. Sustainable Energy Conversion from Biomass Waste Combustion

    Author : Maulana Nugraha; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particle modelling; furnace; particulate matter; Stefan flow; computational fluid dynamics CFD ; orthogonal collocation; biomass waste combustion;

    Abstract : Various biomass-type conversions into sustainable heat and power, from dedicated crops to solid biomass waste via the combustion process, are at the center of scientific and industrial focus today. However, biomass combustion contribution to global particulate matter (PM) emission has become one of the biggest challenges that remain in the development of sustainable biomass combustion systems.

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical modelling; particle model; bed model; CFD simulation; biomass; pyrolysis; ; combustion; gasification; potassium release; alkali;

    Abstract : The use of biomass as a renewable source of energy has been increasing over the past few decades, and biomass is regarded as a promising replacement for fossil fuels. Thermochemical conversion of biomass is a common approach for biomass utilization with a relatively short conversion time. READ MORE

  6. 4. 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

  7. 5. Effect of chemical and physical properties on combustion of biomass particle

    Author : Amit Biswas; Fabrizio Scala; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Biomass combustion is an interesting alternative to fossil fuel. Modeling and simulation is used for design optimization of biomass boilers and furnace. It is difficult to develop a sufficiently accurate and computationally efficient model because the combustion system is highly complicated multi-scale, multi-phase and multi-physics problem. READ MORE
