  1. 1. Radiative Heat Transfer in Suspension-Fired Systems

    Författare :Adrian Gunnarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-firing; rotary kiln; combustion; Radiative heat transfer; soot volume fraction;

    Sammanfattning : Radiation is the dominating heat transfer mechanism in most furnaces, and the radiative properties of combustion products represent important aspects regarding its suitability as a heat source. However, fuel and energy markets are undergoing rapid changes due to increasing concerns related to the security of supply and increased global warming. LÄS MER

  3. 2. Experimental and modelling studies of radiative heat transfer in flames

    Författare :Daniel Bäckström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence-Radiation Interaction; Particle radiation; Radiative heat transfer;

    Sammanfattning : Combustion of solid fuels is used extensively for electricity generation purposes. However, combustion of fossil fuels leads to CO2 emissions which enhance the greenhouse gas effect. Carbon capture and storage (CCS) is a proposed solution where the CO2 is captured and stored instead of being emitted to the atmosphere. LÄS MER
