1. Co-firing complex biomass in a CFB boiler : ash transformation, corrosion control and materials selection
Sammanfattning : The effects of greenhouse gas net emissions on global warming, stricter legislation on waste handling, and the pursuit of ever cheaper heat- and power production are all important factors driving the introduction of complex fuels in incineration plants. However - without fundamental knowledge regarding ash transformation, corrosion control, and materials selection – this introduction of potentially economically and environmentally beneficial fuels, might instead cause economic loss and environmentally adverse effects.

2. Methods to Generate Size- and Composition Controlled Aerosol Nanoparticles
Sammanfattning : This thesis describes experiments performed using different methods to produce aerosol nanoparticles with control over size and composition. The process included differential mobility analyzers (DMAs) as size-selecting instruments and tube furnaces for particle synthesis. LÄS MER
3. Aluminium alloy property data in engineering design
Sammanfattning : The vast amount of materials existing today and the fastdevelopment of new and modified ones make it favourable to haveaccess to computerised materials property data. The advantagesare fast access and the possibility to process datainstantaneous. LÄS MER
4. Decarbonising the Stainless Steelmaking through Alloy Solutions
Sammanfattning : To reach the goal of the Paris Agreement, the reduction of greenhouse gas emissions (GHG)is becoming one of the most pressing issues in the world today. Unlike most other sectors, thestainless steel industry has a significantly higher burden from upstream emissions comparedto operational emissions. LÄS MER
5. Electron beam-powder bed fusion of Alloy 718 : Effect of process parameters on microstructure evolution
Sammanfattning : Additive manufacturing (AM) is the technology of building 3D parts through layer-by-layer addition of material. Of the different types of AM techniques, electron beam-powder bed fusion (EB-PBF) has been used in this study. EB-PBF can build parts by melting metallic powders using an electron beam as the energy source. LÄS MER
