  5. 3. Characterization of conversion zones in a reciprocating grate furnace firing wet woody biomass

    Author : Narges Razmjoo; Strand Michael; Chungen Yin; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass combustion; Grate firing; Fuel bed; Moisture; Gas phase; Conversion zone; Experimental; Temperature distribution; Gas analysis; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Abstract : 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. READ MORE

  6. 4. Advanced power cycles with mixture as the working fluid

    Author : Maria Jonsson; KTH; []
    Keywords : power cycle; mixture working fluid; Kalina cycle; ammonia-water mixture; reciprocating internal combustion engine; bottoming cycle; gas turbine; evaporative gas turbine; air-water mixture; exergy;

    Abstract : The world demand for electrical power increasescontinuously, requiring efficient and low-cost methods forpower generation. This thesis investigates two advanced powercycles with mixtures as the working fluid: the Kalina cycle,alternatively called the ammonia-water cycle, and theevaporative gas turbine cycle. READ MORE

  7. 5. Tailoring of Transition Metal Silicides as Protective Thin Films on Austenitic Stainless Steel

    Author : Eric Tam; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Rockwell-C adhesion test; X-ray diffractrometry XRD ; Pretorius’ effective heat of formation EHF model; Ion-beam sputter deposition IBSD ; Reciprocating sliding wear test; Corrosion; Stainless steels; Thin films; Tribology; Transition metal silicides; X-ray photoelectron spectroscopy XPS ; Potentiodynamic polarisation measurements;

    Abstract : The objective of this study is to make use of transition metal silicides in a novel way as protective thin films on engineering metals. It can then be possible to take advantage of the potentially good corrosion resistance of metal silicides while compensating for their brittle nature by the ductile bulk material. READ MORE
