  1. 36. Chemical-Looping Combustion with Solid Fuels

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

    Sammanfattning : 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. LÄS MER

  3. 37. Protective Tribofilms on Combustion Engine Valves

    Författare :Robin Elo; Staffan Jacobson; Mikael Åstrand; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internal combustion engine; valve; sealing surface; tribofilm; oil residue; test rig; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : Inside the complex machinery of modern heavy-duty engines, the sealing surfaces of the valve and valve seat insert have to endure. Right next to the combustion, temperatures are high and high pressure deforms the components, causing a small relative motion in the interface. LÄS MER

  4. 38. Laser-Induced Phosphor Thermometry - Feasibility and Precision in Combustion Applications

    Författare :Johannes Lindén; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser-Induced Phosphorescence; Laser Combustion Diagnostics; Non-linearity; Image Intensifier; Two-color Ratio; Lifetime Decay; Precision; Thermographic Phosphors; Temperature measurements; Fysicumarkivet A:2012:Lindén;

    Sammanfattning : Temperature is one of the most fundamental parameters to be measured in many research disciplines. In combustion science, a thorough knowledge of temperature is essential for improving and optimizing combustion processes. LÄS MER

  5. 39. Oxygen-carrier materials for chemical-looping combustion

    Författare :Paul In-Young Cho; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbon Dioxide Capture; and Defluidization.; Carbon Formation; Chemical-Looping Combustion; Oxygen Carrier; CO2 Separation;

    Sammanfattning : For combustion with CO2 capture, chemical-looping combustion (CLC) with inherent separation of CO2 is a promising technology. Two interconnected fluidized beds are used as reactors. In the fuel reactor, a gaseous fuel is oxidized by an oxygen carrier, e.g. LÄS MER

  7. 40. Innovative Oxygen Carriers for Chemical-looping Combustion

    Författare :Dazheng Jing; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical-looping with oxygen uncoupling; Combined manganese oxides; Chemical-looping combustion; CuO-based oxygen carrier; Oxygen carrier;

    Sammanfattning : Chemical-looping combustion (CLC) and chemical-looping with oxygen uncoupling (CLOU) are combustion technologies where carbon dioxide is inherently obtained in pure form without any gas separation step. In the processes, fuel is introduced to the fuel reactor and combustion air is introduced to the air reactor. LÄS MER
