  2. 2. Renewable Energy in Energy-Efficient, Low-Pollution Systems

    University dissertation from Department of Environmental and Energy Systems Studies, Lund university

    Author : Bengt Johansson; Lund University.; Lunds universitet.; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; ethanol; methanol; rape methyl ester; biomass; renewable energy; cogeneration; energy efficiency; scenarios; air pollution; carbon dioxide; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : Energy use accounts for the dominating fraction of total sulphur dioxide (SO2), nitrogen oxide (NOx), volatile organic compounds (VOCs) and carbon dioxide (CO2) emissions. In this thesis, different strategies for reducing these emissions are evaluated, using a bottom-up approach. The thesis is divided in two parts. READ MORE

  3. 3. Air Pollution Dependency on Climate Variability and Source Region : Past, Current and Future Air Pollution Scenarios over Europe

    University dissertation from Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Abstract : BackgroundAir quality in Africa has remained a relatively under-researched field. Most of the African population is dependent on biomass for cooking and heating, with most of the combustion happening in low efficiency stoves in unvented kitchens. READ MORE

  5. 5. Flamelet modelling of soot formation in diffusion flames

    University dissertation from Fire Safety Engineering

    Author : Anne Simone Dederichs; Lund University.; Lunds universitet.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Emissions; Pollution; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : In this work the steady and unsteady flamelet models have been applied to soot formation in laminar and turbulent diffusion flames. The aim was to study how different model parameters affect soot formation in diffusion flames. It was shown that certain assumptions are more crucial in laminar diffusion flames than in turbulent ones. READ MORE
