  4. 7. High-Temperature Fatigue in a Steam Turbine Steel : Modelling of Cyclic Deformation and Crack Closure

    Author : Ahmed Azeez; Robert Eriksson; Kjell Simonsson; Daniel Leidermark; Magnus Hörnqvist Colliander; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Existing conventional thermal power plants are retrofitted for flexible operations to assist the transition toward more renewable energies. The deployment of many renewable energy power plants is necessary to achieve a clean environment with less pollution. READ MORE

  5. 8. Climate change mitigation through CDM : bioenergy technology and energy efficiency in the steel industry

    Author : Chuan Wang; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Abstract : Climate change is one of the most significant challenges to sustainable development facing the international community. Increased attention has been given by industries and governments from both industrialized and developing countries to reduce greenhouse gas (GHG) emissions through the clean development mechanism (CDM), one of the Kyoto Protocol's (KP) flexible mechanisms.

  6. 9. Coated Ferritic Stainless Steels as Interconnects in Solid Oxide Fuel Cells

    Author : Jan Gustav Grolig; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless Steel; Interconnect; SOFC; Chromium volatilization;

    Abstract : Solid oxide fuel cells (SOFCs) have gained increased research interest as they arepromising devices for a decentralized and clean electricity and heat production. Severalmaterial challenges have to be solved to reach sufficient efficiencies and life times. READ MORE

  7. 10. Heat transfer,inclusion characteristics and fluid flow phenomena during up-hill teeming

    Author : Robert Eriksson; KTH; []
    Keywords : Laser flash method; thermal diffusivity; slags; inclusions; water model; ingot casting; up-hill teeming;

    Abstract : Clean steel production requires good control of the sizedistribution and the composition of the inclusions at allstages of the steel making process. So far, there exists verylittle information on the behavior of the inclusion populationduring ingot casting of steel. READ MORE
