  1. 1. Modelling elements in conversion of solid fuels - fixed bed combustion and gaseous radiation

    Author : Robert Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combustion; fixed bed; modelling; solid fuels; gas radiation;

    Abstract : For a long heat and power production by combustion of solid fuels has time been an established technique. Environmental concern of emissions for NOx, SOx and other harmful species has caused an increasingly stricter legislation on the emission levels of the boilers. READ MORE

  2. 2. Combustion Chemistry Investigation of Liquid and Solid Fuels

    Author : Åsa Håkansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gasoline; flame; GC MS; heptane; combustion; pyrolysis; kinetics; emissions; wood; RME;

    Abstract : The aim of this work was to study the combustion of liquid and solid fuels with the emphasis on intermediates and products. Depending on the structure and the complexity of the fuel different reactors and methods were used. Small-scale laboratory reactors were built and chemical analysis and evaluation methods were developed. Heptane. READ MORE

  3. 3. Chemical-Looping Combustion with Solid Fuels

    Author : Henrik Leion; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; petroleum coke; fluidized bed; oxygen carrier; ilmenite; volatiles; gasification; sulphur dioxide; coal; iron oxide; chemical looping combustion; CLC;

    Abstract : In order to meet the global demand of CO2 neutral energy production, chemical-looping combustion could play an important role. With this technique it is possible to capture CO2 without an excessive energy penalty. READ MORE

  4. 4. Detecting, Modelling and Measuring Disturbances in Fixed-bed Combustion

    Author : Sven Hermansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD modelling; solid fuels; grate furnaces; moisture content; fixed bed; combustion;

    Abstract : Combustion of fixed fuel beds in grate furnaces is one of the most common techniques within production of heat and power from solid fuels. The grate furnace used to be a working horse for combustion of hard coal, while today the incitement of using renewable fuel sources has turned biomass and municipal waste into dominating fuel types.

  5. 5. Modeling Aspects of Chemical-Looping Combustion for Solid Fuels

    Author : Pontus Markström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold-flow model; Residence time; Chemical-looping combustion; Solid fuel; Scaling;

    Abstract : Chemical-looping combustion is a novel technology for combustion of fossil fuel. By using a circulating bed material to transfer oxygen to the fuel, a pure stream of carbon dioxide can be obtained from the flue gas, undiluted by nitrogen. READ MORE
