  2. 1. Recycling of Blast Furnace Sludge within the Integrated Steel Plant : Potential for Complete Recycling and Influence on Operation

    Author : Anton Andersson; Lena Sundqvist Ökvist; Hesham Ahmed; Caisa Samuelsson; Yongxiang Yang; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : Ore-based steelmaking generates various residues including dust, sludges, scales and slags. Internal and external recycling has allowed for 68-90 % of the dust, sludges and scales to be recycled. However, several residues are landfilled despite containing elements valuable as raw material in the production of steel. READ MORE

  4. 2. Steam Turbine Optimisation for Solar Thermal Power Plant Operation

    Author : James Spelling; Andrew Martin; Magnus Genrup; KTH; []
    Keywords : solar thermal power; steam-turbine; start-up; cool-down; dispatchability increase; koncentrerad solenergi; ångturbin; uppstart; nedkylning; ökad flexibilitet;

    Abstract : The provision of a sustainable energy supply is one of the most important issues facing humanity at the current time, given the strong dependence of social and economic prosperity on the availability of affordable energy and the growing environmental concerns about its production. Solar thermal power has established itself as a viable source of renewable power, capable of generating electricity at some of the most economically attractive rates. READ MORE

  5. 3. Measures and method characteristics for early evaluation of safe operation in nuclear power plant control room systems

    Author : Eva Simonsen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control room; early development; human factors engineering; safe operation; resilience engineering; evaluation methods; nuclear power;

    Abstract : Safe operation is a central objective for high-risk industries such as nuclear power plants. Operation of the plant is managed from a central control room, which is a complex socio-technical system of physical and organisational structures such as operators, procedures, routines, and operator interfaces.

  6. 4. The Oxy-Fuel Process - Towards high efficient operation

    Author : Fredrik Normann; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oxy-fuel O2 CO2 Combustion NOx Thermal-NO Co-production;

    Abstract : The power generation system is facing large changes to meet the demands on reduced emissions of carbon dioxide (CO2). Oxy-fuel combustion with capture of CO2 is a promising option to meet those demands. READ MORE

  7. 5. Hydropower plants and power systems : Dynamic processes and control for stable and efficient operation

    Author : Weijia Yang; Per Norrlund; Urban Lundin; Christophe Nicolet; Uppsala universitet; []
    Keywords : ;

    Abstract : As the largest global renewable source, hydropower shoulders a large portion of the regulation duty in many power systems. New challenges are emerging from variable renewable energy (VRE) sources, the increasing scale and complexity of hydropower plants (HPPs) and power grid. READ MORE
