1. Fuel conversion and ash formation interactions : a thermochemical study on lignocellulosic biomass
Sammanfattning : Biomass is considered to be CO2 neutral, and to be able to reduce the dependency on fossil fuels the need for expanded and sustainable biomass feedstock is increasing. Ash-related problems are some of the most important aspects of this increasing use of new biomass assortments in thermal energy conversion systems. LÄS MER
2. Gardens in the Wasteland : Christian Formation in Three Swedish Church Plants
Sammanfattning : Gardens in the Wasteland is an ethnographic study of Christian formation within three Swedish church plants working against a backdrop of advanced secularisation. The thesis analyses the formative practices employed by these church plants with the intention of forming persons towards a lived Christian identity. LÄS MER
3. NOx Formation in Rotary Kilns for Iron Ore Pelletization
Sammanfattning : The production of iron ore pellets is often performed in the so-called Grate-Kiln process. The aim of the process is to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing. LÄS MER
4. NOx formation in iron ore rotary kilns
Sammanfattning : Iron ore pellets are often produced using the so-called Grate-Kiln process, which is designed to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing. The heat required for this process comes from the combustion of a pulverized fuel in a rotary kiln, involving the formation of a jet flame. LÄS MER
5. Phase chemistry in process models for cement clinker and lime production
Sammanfattning : The goal of the thesis is to evaluate if developed phase chemical process models for cement clinker and lime production processes are reliable to use as predictive tools in understanding the changes when introducing sustainability measures.The thesis describes the development of process simulation models in the application of sustainability measures as well as the evaluation of these models.
