  1. 1. Reduction of the N2O Emission from Fluidized Bed Combustion by Afterburning

    Författare :Lennart Gustavsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical modelling; fuel injection; nitrous oxide; fluidized bed combustion; fluidized beds; afterburning; homogeneous heterogeneous reactions; N2O reduction; fluidized bed boiler; N2O emissions;

    Sammanfattning : A method for reducing N2O emissions from fluidized bed combustion is presented and investigated. In contrast to flame combustion, fluidized bed combustion generates significant amounts of nitrous oxide (N2O) which are emitted to the atmosphere. LÄS MER

  3. 2. Post-Detonation Afterburning of High Explosives

    Författare :Katja Fedina; Strömningsteknik; []
    Nyckelord :Explosives; Combustion; LES; Finite rate chemistry; Explosives; Combustion; LES; Finite rate chemistry; Height of Burst;

    Sammanfattning : High performance of an explosive compound with respect to afterburning requires sufficient combustible properties of the explosive, and a careful determination of the most appropriate charge positioning to achieve the desired afterburning effect. Understanding the physical processes of post-detonation afterburning and how these are affected by the surroundings, e. LÄS MER

  4. 3. Automatic Reduction Procedures for Chemical Mechanisms in Reactive Systems

    Författare :Terese Lövås; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mechanism Reduction; Combustion; Physics; Emissions; Fysik; Fysicumarkivet A:2002:Lövås;

    Sammanfattning : To deal with complex physical and chemical processes in reactive systems, such as combustion processes, it is necessary to find methods that simplify modelling in such a way that it becomes both more comprehensible and practically useful. In the work reported here a method for automatically reducing chemical reaction mechanisms has been developed for use in computer simulations of various combustion systems. LÄS MER
