1. Chemical Properties of FBC Ashes
Abstract : In this thesis several aspects of ash chemistry are discussed. An issue of primary concern for boiler operators is the formation of ash deposits. New biomass fuels are introduced, many of which have unfavourable ash melting behaviour due to high levels of alkali metal species and chlorine. READ MORE

2. Leaching, filtration and displacement washing in a treatment process for MSW combustion fly ash - laboratory scale and plant studies
Abstract : Municipal Solid Waste combustion, as one of the waste management tools, starts to play an important role nowadays in heat and energy generation. However, MSW combustion leads to generation of other wastes - combustion residues, including ashes, which require a proper management. READ MORE

3. Metals in MSWI fly ash - problems or opportunities?
Abstract : Incineration of municipal solid waste is a commonly used management method to take care of our waste. However, the residues produced are a problem. They often contain large amounts of potentially toxic metal compounds and soluble salts, which can cause harm to the environment and human health if released from the ash. READ MORE

4. Unsaturated Phase Environmental Processes in MSWI Bottom Ash
Abstract : Every year, Sweden produces 1.5 million tons of incineration residues from waste to energy plants. Among these residues bottom ash(BA) due to its large volume and good geotechnical quality can be reused as an alternative construction material. READ MORE

5. Choice of bed material: a critical parameter in the optimization of dual fluidized bed systems
Abstract : Dual Fluidized Bed (DFB) gasification is a promising alternative method for the production of biofuels. In the DFB gasification process, the bed material, which is a crucial component of the process, has two possible roles: 1) to provide the heat needed for the gasification reaction; and 2) if it has catalytic properties, to improve the quality of the produced gas.
