2. 1. Characterization of oxy-fuel flames - their composition, temperature and radiation

   Author : Klas Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; O2 CO2; NO formation; Radiation; Oxy-fuel; Flame properties;

   Abstract : Oxy-fuel combustion is receiving growing attention as one of the promising CO2 capture technologies in connection to power production. Yet, significant efforts are required in research and development of this combustion process in order to be able to design and optimize a full scale power plant. READ MORE

4. 2. Experimental and modelling studies of radiative heat transfer in flames

   Author : Daniel Bäckström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence-Radiation Interaction; Particle radiation; Radiative heat transfer;

   Abstract : Combustion of solid fuels is used extensively for electricity generation purposes. However, combustion of fossil fuels leads to CO2 emissions which enhance the greenhouse gas effect. Carbon capture and storage (CCS) is a proposed solution where the CO2 is captured and stored instead of being emitted to the atmosphere. READ MORE

5. 3. Experimental and modelling studies of particle radiation in flames

   Author : Daniel Bäckström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Combustion of solid fuels is an important part of many industrial and power generation processes. The global use of coal in these processes is vast and thus also the related emissions of CO2 to the atmosphere. It is not possible to continue on the path with continuously increasing emissions of CO2 if the global climate targets should be met. READ MORE

6. 4. Modeling of Pulverised Wood Flames

   Author : Ashraf Elfasakhany; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied thermodynamics; Thermal engineering; Energiforskning; Energy research; plasma; combustion; pulverised wood; two-phase flow; devolatilization; emissions; Gases; fluid dynamics; plasmas; fluiddynamik; Gaser; Termisk teknik; termodynamik;

   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

7. 5. Detailed Soot Modelling in Laminar and Turbulent Reacting Flows

   Author : Michael Balthasar; Förbränningsmotorer; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; soot; turbulent; flames; engines; turbines; carbon black; ionization; laminar; Physics; Fysik; Fysicumarkivet A:2000:Balthasar;

   Abstract : In the present work a detailed kinetic soot model is applied to study the formation and oxidation of soot particles in laminar premixed and turbulent non-premixed flames. The soot model used in this study is based on a detailed description of the chemical and physical processes involved in the formation of soot. READ MORE
