1. 6. Externally fired gas turbine cycle based on biomass gasification gas as fuel

   Författare :Fabiola Baina Veizaga; Torsten Fransson; Lasse Rosendhal; KTH; []
   Nyckelord :Externally fired micro gas turbine; heat transfer; combustion of biomass derived gas; micro combined heat and power; Energiteknik; Energy Technology;

   Sammanfattning : Energy services are essential for the development of societies, reduce poverty, and improve the living standards of inhabitants. The conventional routes to provide energy services employ fossil fuels. However, this involves environmental and availability concerns. LÄS MER

3. 7. Combustion of gasified biomass: : Experimental investigation on laminar flame speed, lean blowoff limit and emission levels

   Författare :Nur Farizan Binti Munajat; Torsten Fransson; Catharina Erlich; Jens Klingmann; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass gasification; gasified biomass; laminar flame speed; blowoff; emissions;

   Sammanfattning : Biomass is among the primary alternative energy sources that supplements the fossil fuels to meet today’s energy demand. Gasification is an efficient and environmental friendly technology for converting the energy content in the biomass into a combustible gas mixture, which can be used in various applications. LÄS MER

4. 8. Comparative study of residue pellets from cane sugar and palm-oil industries with commercial wood pellets, applied in downdraft gasification

   Författare :Catharina Erlich; Torsten Fransson; Björn Zethraeus; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy engineering; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

   Sammanfattning : While biomass utilization for energy conversion in the industrialized nations is being largely developed, highly efficient and environmentally friendly, many tropical countries still use biomass at low efficiencies and high emission levels. The main reasons for these gaps are both political and technological: the energy markets are different, the Gross National Product (GDP) differs widely, and the feedstock differs in form and conversion behaviour.

5. 9. Development and characterization of functional composite materials for advanced energy conversion technologies

   Författare :Liangdong Fan; Bin Zhu; Torsten Fransson; Mahmut D. MAT; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low temperature ceramic fuel cell; Ceria-carbonate composite; Electrolysis; Transition metal oxide; Symmetrical fuel cells; All-nanocomposite fuel cell; Electrolyte-free fuel cell; Solar cell; ion conductor and semiconductor; SRA - Energy; SRA - Energi;

   Sammanfattning : The solid oxide fuel cell (SOFC) is a potential high efficient electrochemical device for vehicles, auxiliary power units and large-scale stationary power plants combined heat and power application. The main challenges of this technology for market acceptance are associated with cost and lifetime due to the high temperature (700-1000 oC) operation and complex cell structure, i. LÄS MER

7. 10. Educational evaluation of an interactive multimedia learning platform : computerized educational platform in heat and power technology

   Författare :Vitali Fedulov; Torsten Fransson; Ambjörn Naeve; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; e-learning; computerized education; knowledge management; pedagogy; technology enhanced learning; Education; Pedagogik;

   Sammanfattning : Learning materials have multiple forms, such as books, overhead slides, computer files, blackboard notes by teachers, narration to the notes, video/audio tapes etc. Since the forms are highly inhomogeneous, it becomes difficult to collect and practically use them by a particular learner for individual study at home.
