11. Advanced Laser-based Multi-scalar Imaging for Flame Structure Visualization towards a Deepened Understanding of Premixed Turbulent Combustion
Sammanfattning : The work presented in the thesis concerns the developments of laser-based diagnostics and its application to the study of turbulent premixed combustion. The diagnostic developments, mainly concerned with planar laser-induced fluorescence (PLIF), are intended to provide instantaneous visualization of the key species originating from the combustion processes involved in the burning of hydrocarbons and nitrogen-containing fuels under turbulent conditions.

12. 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
13. Wall Related Lean Premixed Combustion Modeled with Complex Chemistry
Sammanfattning : Increased knowledge into the physics and chemistrycontrolling emissions from flame-surface interactions shouldhelp in the design of combustion engines featuring improvedfuel economy and reduced emissions. The overall aim of this work has been to obtain afundamental understanding of wall-related, premixed combustionusing numerical modeling with detailed chemical kinetics. LÄS MER
14. Characterization of the Combustion of Light Alcohols in CI Engines : Performance, Combustion Characteristics and Emissions
Sammanfattning : Alternative fuels for combustion engines are becoming increasingly popular as society is pushing to phase out fossil energy to reduce CO2 emissions. The compression ignition (CI) engine has a high overall efficiency which makes it a valuable option for the transport fleet, despite the well known NOx and soot pollutants it emits. LÄS MER
15. Characterization of conversion zones in a reciprocating grate furnace firing wet woody biomass
Sammanfattning : Grate-firing systems are a common and popular combustion technology for burning biomass. However, combustion of biomass in these furnaces may emit a large amount of pollutants in the form of CO, CH4, PAH, NOx, and particles. LÄS MER
