  2. 1. 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

  4. 2. Steam Turbine Thermal Modeling for Improved Transient Operation

    Author : Monika Topel; Björn Laumert; Konstantinos Kyprianidis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steam turbines; transients; start-up; finite element model; heat transfer; Energy Technology; Energiteknik;

    Abstract : The growing shares of renewable energy sources in the market and solar thermal power applications have set higher requirements on steam turbine operation.These requirements are related to flexibility during transients. A key aspect sought of such flexibility is the capability for fast starts. READ MORE

    Abstract : Gas turbines, in simple and combined cycle, are common and economically profitable on the power generating market today. Several new cycles have been proposed as future competing technologies, but all studies about these cycles have, so far, been paperwork. READ MORE

  6. 4. Improving Concentrating Solar Power Plant Performance through Steam Turbine Flexibility

    Author : Monika Topel; Björn Laumert; Markus Jöcker; Magnus Genrup; Tony Arts; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concentrating Solar Power; Steam Turbines; Transients; Start-up; Energy Technology; Energiteknik;

    Abstract : The amount of incoming solar energy to earth is greater than any other source. Among existing technologies to harness solar energy there is concentrating solar power (CSP). One advantage of CSP is that is dispatchable, meaning that it can provide power even when the sun is not shining. READ MORE

  7. 5. Humidification Processes in Gas Turbine Cycles

    Author : Marcus Thern; Kraftverksteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied thermodynamics; Thermal engineering; Energiforskning; Energy research; HAT; Biomass; Biofuel; Humidification; Evaporation; Evaporative gas turbine ; Humid air turbine ; Termisk teknik; termodynamik;

    Abstract : The global climate change caused by emissions of greenhouse gases from combustion processes has been recognized as a continuously growing problem and much research focuses on improving the environmental performance of gas turbines. The potential of improving gas turbine component efficiencies has become smaller each decade and therefore, thermodynamic cycles have become more interesting for power producing units. READ MORE
