2. 1. Investigation of Emission Characteristics for Diluted Flames and Renewable Fuels in Gas Turbine Combustors

   Author : Fredrik Hermann; Kraftverksteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; framdrivningssystem; Motorer; termodynamik; Motors and propulsion systems; Termisk teknik; applied thermodynamics; Thermal engineering; combustor rig experiments; combustor reactor models; synthetic fuel; liquid fuel; gaseous fuel; UHC; CO; NOx; emission measurements; CO2 enriched; humidified combustion; diluted combustion; premixed combustion; Gas turbine; combustion chamber; Energiforskning; Energy research;

   Abstract : Gas turbines have served as economically profitable and reliable generators of power for the past few decades, and have mainly been used in simple and combined cycles. The increased restrictions on hazardous emissions and the increased demand for profitability have created new prospects for innovative power cycles. READ MORE

4. 2. Turbulent Swirl Flow Modeling for Combustor Applications

   Author : Andrej V. Smirnov; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Numerical simulations of three-dimensional confined swirl flows in a combustion chamber geometry are carried out with improved turbulence and combustion models. In the first part of the work a comparative study of six turbulence models is done in application to swirl flow. READ MORE

5. 3. Fluidized-Bed Reactor Systems for Chemical-Looping Combustion with Inherent Separation of CO2

   Author : Eva Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical-Looping Combustion; Interconnected Fluidized Beds; Carbon Dioxide Capture;

   Abstract : In chemical-looping combustion (CLC) a gaseous fuel can be burnt with inherent separation of carbon dioxide. The system consists of two reactors, a fuel reactor and an air reactor and an oxygen-carrier in the form of metal oxide particles that transports oxygen from the air to the fuel. READ MORE

6. 4. Design, modelling and operation of a 100 kW chemical-looping combustor for solid fuels

   Author : Pontus Markström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; Fluidised beds; Chemical-looping combustion; Modelling; Carbon capture and storage; Oxygen carriers;

   Abstract : With the increasing threat of global warming, technologies for efficient capture and storage of the greenhouse gas CO2 are sought after. Chemical-looping combustion is a novel CO2 capture technology that can be applied when burning gaseous, liquid or solid fuels. READ MORE

7. 5. Automatic Analysis and Reduction of Reaction Mechanisms for Complex Fuel Combustion

   Author : Daniel Nilsson; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydraulik; Complex fuel combustion; Reduced kinetic models; skeletal mechanism; QSSA; hydraulics; Mechanical engineering; vacuum technology; Maskinteknik; vibration and acoustic engineering; vakuumteknik; vibrationer; akustik; Physics; Fysik; Chemistry; Kemi; Fysicumarkivet A:2001:Nilsson;

   Abstract : This work concentrates on automatic procedures for simplifying chemical models for realistic fuels using skeletal mechanism construction and Quasi Steady-State Approximation (QSSA) applied to detailed reaction mechanisms. To automate the selection of species for removal or approximation, different indices for species ranking have thus been proposed. READ MORE
