  1. 1. Experimental study of a Volatiles Distributor for Improving the Cross-sectional Gas Distribution in Fluidized Beds

    Författare :Xiaoyun Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel reactor; Fluidization regimes; Gas-solid contacting; Biomass; Chemical looping combustion; Volatiles distributor; Internal baffles; CO2 removal;

    Sammanfattning : Chemical looping combustion (CLC) is a promising carbon capture technology due to its inherent CO2 separation. Significant progress has been made in CLC of solid fuels in recent years. LÄS MER

  3. 2. Fluid Dynamics of the Bottom Bed of Circulating Fluidized Bed Boilers

    Författare :Anders Svensson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluidized beds; circulating fluidized bed boilers; fluctuations; fluidization regimes; bottom bed; bed porosity; fluid dynamics; bubbling beds; circulating fluidized beds; non-slugging; bed expansion; particle concentration;

    Sammanfattning : The fluid dynamic conditions in the furnace of a fluidized bed boiler influence the combustion and the production of harmful emissions. A substantial amount of the bed material in a circulating fluidized bed (CFB) boiler is present as a dense bubbling bottom bed. LÄS MER
