  1. 1. Oxy-coal combustion and its integration with power systems for CO2 capture

    Författare :Yukun Hu; Jinyue Yan; Roland Span; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxy-coal combustion; flue gas recycle; radiation; peak and off-peak operations; cryogenic CO2 purification;

    Sammanfattning : Oxy-fuel combustion is one of the technologies for carbon dioxide (CO2) capture and storage (CCS) in fossil fuel based power systems to mitigate global greenhouse gases (GHGs) emissions. When introducing oxy-fuel combustion into the power systems, energy penalty for CCS has significant impacts on the system performance. LÄS MER

  3. 2. The Fate of Sulfur during Oxy-Fuel Combustion

    Författare :Daniel Fleig; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pulverized coal combustion; oxy-coal; SO3; Oxy-fuel; SO2; sulfur;

    Sammanfattning : Oxy-fuel combustion, where air is replaced by O2 and recycled flue-gas to enrich combustion products, is one of the main CO2 capture technologies suitable for large-scale coal-fired power plants. The changed combustion conditions in oxy-fuel combustion influences the sulfur chemistry, which has recently been the subject of increased attention due to the importance of sulfur species in corrosion and flue-gas cleaning issues.

  4. 3. Experimental and Modeling Studies of Sulfur-Based Reactions in Oxy-Fuel Combustion

    Författare :Daniel Fleig; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SO3; acid dew-point; coal combustion; oxy-fuel; sulfur; flue gas recycle; corrosion; Carbon capture and storage; H2SO4; SO2;

    Sammanfattning : Oxy-fuel combustion is a technology for CO2 capture that is suitable for large-scale, coal-fired power plants. In this system, the combustion air is replaced by a mixture of O2 and recycled flue gases, so as to enrich for CO2 in the flue gas. LÄS MER

  5. 4. Radiative Properties and Combustion Chemistry in Oxy-Fuel Flames – Experiments and Modelling Elements

    Författare :Stefan Hjärtstam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Numerical modelling; Oxy-fuel; Global mechanism; Combustion;

    Sammanfattning : The current understanding of global warming translates into an urgent need to reduce anthropogenic CO2 emissions. Carbon capture and storage is a measure to reduce CO2 emissions and oxy-fuel combustion is emerging as one possible CO2 capture process. LÄS MER
