1. Radiative Properties and Combustion Chemistry in Oxy-Fuel Flames – Experiments and Modelling Elements
Abstract : The current understanding of global warming translates into an urgent need to reduce anthropogenic CO2 emissions. Carbon capture and storage is a measure to reduce CO2 emissions and oxy-fuel combustion is emerging as one possible CO2 capture process. READ MORE

2. Pyrolysis of biomass in fluidized-beds: in-situ formation of products and their applications for ironmaking
Abstract : The iron and steel industry emitted 8 % of all CO2 emissions in Sweden, 2011. Investigating alternative energy carriers is the purpose of this thesis. By pyrolyzing biomass, an energetic solid, gaseous and liquid (bio oil) fraction is obtained. READ MORE

3. Oxy-coal combustion and its integration with power systems for CO2 capture
Abstract : Oxy-fuel combustion is one of the technologies for carbon dioxide (CO2) capture and storage (CCS) in fossil fuel based power systems to mitigate global greenhouse gases (GHGs) emissions. When introducing oxy-fuel combustion into the power systems, energy penalty for CCS has significant impacts on the system performance. READ MORE

4. Detecting, Modelling and Measuring Disturbances in Fixed-bed Combustion
Abstract : Combustion of fixed fuel beds in grate furnaces is one of the most common techniques within production of heat and power from solid fuels. The grate furnace used to be a working horse for combustion of hard coal, while today the incitement of using renewable fuel sources has turned biomass and municipal waste into dominating fuel types.

5. CFD Simulation of Jet in Asymmetric Co-flows in a Down-scaled Rotary Kiln Model
Abstract : Rotary kilns are industrial furnaces that have been widely used in limestone calcination, cement industry and hazardous waste incineration for centuries. In this work a rotary kiln used for the iron ore pellet sintering process in the grate-kiln pelletizing system has been studied. READ MORE
