  2. 1. CFD Modelling of Hydrogen Rich Biomass Syngas Combustion

    Author : Nikolaos Papafilippou; Rikard Gebart; Kentaro Umeki; Muhammad Aqib Chishty; Christophe Duwig; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; RANS; LES; FGM; Turbulent Combustion; Numerical Combustion; Swirling Flows; Gas Turbines; Biomass Syngas; Hydrogen; Energiteknik; Energy Engineering;

    Abstract : The loss of biodiversity, due to pollution and global warming, is more important and relevant now than it has ever been. Man made climate warming has its roots in the huge amount of CH4 and CO2 emissions, which have increased by 47% and 156% respectively since 1750. READ MORE

  4. 2. Combustion of gasified biomass: : Experimental investigation on laminar flame speed, lean blowoff limit and emission levels

    Author : Nur Farizan Binti Munajat; Torsten Fransson; Catharina Erlich; Jens Klingmann; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass gasification; gasified biomass; laminar flame speed; blowoff; emissions;

    Abstract : Biomass is among the primary alternative energy sources that supplements the fossil fuels to meet today’s energy demand. Gasification is an efficient and environmental friendly technology for converting the energy content in the biomass into a combustible gas mixture, which can be used in various applications.

  5. 3. Catalytic combustion of gasified waste

    Author : Henrik Kusar; KTH; []
    Keywords : Catalytic combustion; Gasified waste; LHV-fuel; RDF; Biomass; Selective catalytic oxidation; NH3; NOX; Palladium; Platinum; Hexaaluminate; Garnet; Spinel; Deactivation; Sulphur; Poisoning;

    Abstract : This thesis concerns catalytic combustion for gas turbineapplication using a low heating-value (LHV) gas, derived fromgasified waste. The main research in catalytic combustionfocuses on methane as fuel, but an increasing interest isdirected towards catalytic combustion of LHV fuels. READ MORE

  6. 4. Design and Operation of a Chemical-Looping Reformer for Catalytic Upgrading of Biomass-Derived Gas
