  2. 1. Thermodynamic aspects and heat transfer characteristics of HiTAC furnaces with regenerators

    Author : Nabil Rafidi; Wlodzimierz Blasiak; John Witton; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; flameless; oxy-fuel; heat-recirculation; gas-recirculation; heat transfer; furnace; radiant-tube; regenerative burner; honeycomb; fixed-bed; Thermal energy engineering; Termisk energiteknik;

    Abstract : Oxygen-diluted Combustion (OdC) technology has evolved from the concept of Excess Enthalpy Combustion and is characterized by reactants of low oxygen concentration and high temperature. Recent advances in this technology have demonstrated significant energy savings, high and uniform thermal field, low pollution, and the possibility for downsizing the equipment for a range of furnace applications.

  4. 2. Modelling and Experimental Investigations on Thermal Radiation in Combustion Environments

    Author : Henrik Hofgren; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal radiation; Property model; SNB; WSGG; LBL; Planck; particle; fly-ash; soot; grate; furnace; combustion;

    Abstract : Thermal radiation is an important physical phenomenon in combustion environments. For the understanding of existing- and the design of new combustion environments computational modelling is a useful tool as it can describe the different transport phenomena. READ MORE

  5. 3. 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.

  6. 4. Sustainable Energy Conversion from Biomass Waste Combustion - Experimental and Multiscale Modelling Studies

    Author : Maulana Nugraha; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stefan flow; particulate matter; biomass; combustion; soot; furnace; orthogonal collocation; CFD simulation;

    Abstract : The development of sustainable energy conversion via residual biomass combustion is one of the scientific and industrial community focus today to fulfilling the global net zero emission commitment in 2050. Despite its potency due to the abundant stock of biomass, hazardous particulate matter (PM) emission from residual biomass combustion remains a big challenge to increase the contribution of biomass combustion as a main renewable energy source.
