1. Analysis of the cold flow field in a rotary kiln
Abstract : The pelletizing process where the crude ore from the mine is upgraded to pellets is a process which includes several stages involving complex fluid dynamics. In this thesis, focus is on the grate-kiln pelletizing process and especially on the rotary kiln, with the objective to get a deeper understanding of the aerodynamics and its influence on the combustion process.

2. Modeling Aspects of Chemical-Looping Combustion for Solid Fuels
Abstract : Chemical-looping combustion is a novel technology for combustion of fossil fuel. By using a circulating bed material to transfer oxygen to the fuel, a pure stream of carbon dioxide can be obtained from the flue gas, undiluted by nitrogen. READ MORE

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

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

5. Solids flows in circulating fluidized beds: explorations of phenomena with applications to boilers
Abstract : The circulating fluidized bed (CFB), which is a technology that is commonly used in the heat and power sector, efficiently converts renewable and/or and low-grade solid fuels, such as biomass and biogenic waste fractions. CFB units serve also as a technological platform for carbon capture processes (combustion by oxy-firing or chemical looping), which are foreseen to play a key role in the transition of the energy system towards decreased atmospheric CO2 emissions.
