2. 1. Process-microstructure-corrosion interrelations for stainless steel

   Author : David Lindell; Rachel Pettersson; Rebecca L. Higginson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; processing; annealing; pickling; microstructure; corrosion; anisotropy; oxyfuel; Kemi; Chemistry;

   Abstract : Stainless steels were first developed in the early 20th century and have since then emerged as a very diverse class of engineering materials. Along with steels having new combinations of properties, there is a continuous development of new technologies allowing the material to be produced in a faster and more energy effcient manner.

4. 2. Opportunities and uncertainties in the early stages of development of CO2 capture and storage

   Author : Mårten Lind; Mats Westermark; Mohsen Assadi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acceptance; cement; CCS; CO2 capture and storage; early opportunities; enhanced oil recovery; expert opinions; hybrid power cycles; optimism; oxyfuel combustion; pressurised fluidised bed combustion; pilot plant; potassium carbonate; risk; Sargas; scenario studies; scientific uncertainty; stakeholder perceptions; Chemical process and manufacturing engineering; Kemisk process- och produktionsteknik;

   Abstract : The topic of this thesis is carbon dioxide (CO2) capture and storage (CCS), which is a technology that is currently being promoted by industries, scientists and governments, among others, in order to mitigate climate change despite a continued use of fossil fuels. Because of the complex nature of CCS and the risks it entails, it is controversial. READ MORE

5. 3. Sustainability measures in quicklime and cement clinker production

   Abstract : This thesis investigates sustainability measures for quicklime and cement clinker production. It is the aim of this thesis to contribute to the effort of creating a more sustainable modus of industrial production. READ MORE

6. 4. Fast devolatilization of biomass : An experimental study using high-speed imaging, relevant for suspension firing technologies

   Author : Angel David Garcia Llamas; Kentaro Umeki; Florian Schmidt; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

   Abstract : We have performed experiments using imaging techniques in a flame-assisted, drop-tube reactor with optical access, to extract information relevant to the improvement of multi-particle devolatilization models. These models could be of interest for different suspension firing techniques, such as entrained flow biomass gasification, (EFBG) and oxyfuel combustion. READ MORE

7. 5. Impacts of alternative combustion diluents and hydrogen addition on a swirl-stabilized flame related to gas turbine application

   Author : Mao Li; Kraftverksteknik; []
   Keywords : lean premixed combustion; Swirl-stabilized flame; Gas turbine combustion; Flame dilution; H2 addition; Lean blowout; CO emission; PVC; CH chemiluminescence; Inverse Abel transform; PIV; POD;

   Abstract : The global energy tendency leads to increasing attention on clean combustion technologies in order to eliminate adverse impacts on the environment. The utilization of oxyfuel combustion (CO2 acts as the only combustion dilution), flame diluents, and hydrogen fuel in gas turbine combustion provides a promising solution to reduce combustion pollutant emissions.
