1. Formation of Nitrogen Oxides during Combustion
Sammanfattning : The formation of nitrogen oxides during combustion of coal is a complex process involving both homogeneous and heterogeneous reaction step. In this thesis HCN and NH3 are used as model compunds for the nitrogen containing pyrolysis products... LÄS MER
2. Nutrient recovery from waste streams through struvite formation
Sammanfattning : Eutrophication or the nutrient enrichment of water bodies, typically by nitrogen and phosphorus has adversely affected the aquatic life and the quality of water. Governments have been forced to take actions in order to reduce the release of these nutrients into the environment. 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. Microstructure and properties of welds in the lean duplex stainless steel LDX 2101
Sammanfattning : Duplex stainless steels can be very attractive alternatives to austenitic grades due to their almost double strength at equal pitting corrosion resistance. When welding, the duplex alloys normally require addition of filler metal, while the commodity austenitic grades can often be welded autogenously. LÄS MER
5. Welds in the lean duplex stainless steel LDX 2101 : effect of microstructure and weld oxides on corrosion properties
Sammanfattning : Duplex stainless steels are a very attractive alternative to austenitic grades due to their higher strength and good corrosion performance. The austenitic grades can often be welded autogenously, while the duplex grades normally require addition of filler metal. LÄS MER
