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. Ash chemistry and fuel design focusing on combustion of phosphorus-rich biomass
Abstract : Biomass is increasingly used as a feedstock in global energy production. This may present operational challenges in energy conversion processes which are related to the inorganic content of these biomasses. As a larger variety of biomass is used the need for a basic understanding of ash transformation reactions becomes increasingly important. READ MORE

3. Co-firing animal waste, sludge, residue wood, peat and forest fuels in a 50MWth CFB boiler : ash transformation, availability and process improvements
Abstract : The direct variable costs for heat and electricity production based on solid biomass fuel combustion is approximately 3-5 times lower than the costs in a fossil fuel-oil based boiler in Sweden. In addition waste derived biomass fuels are typically much cheaper than biomass not classified as waste. READ MORE

4. Application of fuel design to mitigate ash-related problems during combustion of biomass
Abstract : The energy supply of today is, through the use of fossil energy carriers,contributing to increased net emissions of greenhouse gases. This hasseveral negative effects on our environment and our climate. In order toreduce the impact of this, and possibly to reverse some of the effects, allrenewable energy sources must be used.

5. Ash transformation during thermochemical conversion of agricultural biomass in entrained flow conditions
Abstract : Agricultural biomass is considered a prospective renewable feedstock in the energy conversion units. Despite its widespread availability, agricultural biomass is often underutilized in the thermochemical processes due to its high ash content. READ MORE
