1. Modelling of Biomass Combustion in Furnaces
Sammanfattning : Biomass combustion in grate fired furnaces is an important approach to convert renewable biomass fuel to heat and electricity. It is not only used in the Swedish energy industry but also by a great number of Swedish households for domestic heating. Burning biomass has the advantage of being CO2 neutral. LÄS MER
2. Design of advanced industrial furnaces using numerical modeling method
Sammanfattning : This doctoral thesis describes the fundamentals ofmathematical modeling for the industrial furnaces and boilersand presents the results from the numerical simulations of sometypical applications in advanced industrial furnaces andboilers. The main objective of this thesis work is to employcomputational fluid dynamics (CFD) technology as an effectivecomputer simulation tool to study and develop the newcombustion concepts, phenomena and processes in advancedindustrial furnaces and boilers.

3. Ash Behavior in Fluidized-Bed Combustion and Gasification of Biomass and Waste Fuels : Experimental and Modeling Approach
Sammanfattning : Over the past few decades, a growing interest in the thermal conversion of alternative fuels such as biomass and waste-derived fuels has been observed among the energy-producing companies. Apart from meeting the increasing demand for sustainable heat and power production, other advantages such as reducing global warming and ameliorating landfilling issues have been identified. LÄS MER
4. High temperature corrosion during waste incineration : characterisation, causes and prevention of chlorine-induced corrosion
Sammanfattning : Waste-fired boilers suffer severely from corrosion of critical components such as superheater tubes. In this work the high temperature corrosion of candidate superheater alloys have been investigated by detailed laboratory studies and controlled field exposures in full-scale boilers. LÄS MER
5. Particles from biomass combustion -Characteristics and influence of additives
Sammanfattning : AbstractHigh particle concentration in the air is a health risk, and particles from domestic biomass combustion are a significant particle source. In larger boilers, particles are an important element in the build-up of deposits on heat transfer surfaces, causing increased operation and maintenance costs. LÄS MER
