1. 11. Study of possibilities and some problems of using cane residues as fuel in a gas turbine for power generation in the sugar industry

   Författare :Mohamed Gabra; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Sammanfattning : The potential of cane residuals as a source of energy could help many developing countries to improve their balance of payments by decreasing fossil fuels imports and increasing the electrical power production. A substantial increase of the electricity output in the sugar industry could be achieved by using a combined gas turbine/steam turbine integrated with gasifier supplying combustible gas to the gas turbine combustor.

4. 13. Numerical modeling of coupled thermo-hydro-mechanical processes in geological porous media

   Författare :Fuguo Tong; Lanru Jing; Chin-Fu Tsang; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermo-hydro-mechanical processes; Porous geologicalmedia; Numerical modeling; FEM; Multiphase flow; Effective thermal conductivity; Water retention curve; Radioactive waste repositories; Bentonite; ; Geoengineering; Geoteknik;

   Sammanfattning : Coupled Thermo-Hydro-Mechanical (THM) behavior in geological porous media has been a subject of great interest in many geoengineering disciplines. Many attempts have been made to develop numerical prediction capabilities associated with topics such as the movement of pollutant plumes, gas injection, energy storage, geothermal energy extraction, and safety assessment of repositories for radioactive waste and spent nuclear fuel.

5. 14. Material migration in tokamaks : Erosion-deposition patterns and transport processes

   Författare :Armin Weckmann; Marek Rubel; Rudolf Neu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEXTOR; fusion; plasma physics; transport; migration; tracers; tokamak; limiter; divertor; high-Z; ion beam analysis; Rutherford backscattering; Nuclear reaction analysis; Elastic recoil detection analysis; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Controlled thermonuclear fusion may become an attractive future electrical power source. The most promising of all fusion machine concepts is called a tokamak. The fuel, a plasma made of deuterium and tritium, must be confined to enable the fusion process. It is also necessary to protect the wall of tokamaks from erosion by the hot plasma. LÄS MER

7. 15. Determining the Fate and Operational Implications of Alkalis in Chemical Looping Combustion of Biomass

   Författare :Ivan Gogolev; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass; alkali release; chemical looping combustion; carbon capture;

   Sammanfattning : Chemical looping combustion (CLC) of biomass is a promising thermal conversion technology with integrated carbon capture. As with other fluidized bed fuel conversion processes, biomass CLC may be susceptible to issues of agglomeration, fouling and corrosion stemming from the release of alkalis during fuel conversion.
