  1. 6. Availability Analysis of Three Different Types of Combined Cycle Power Plants

    Författare :Javed S. Alvi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCC power plants; NOx reduction; IGCC power plants; Makrov process; repair policies; effectiveness; PFBC power plants; active redundancy; backup fuel reducition;

    Sammanfattning : The goal of power plants with higher efficiency and lower environmental risk than conventional power plants has produced three types of combined cycle power plants. These are: 1) the conventional combined cycle (CCC) power plant, 2) the pressurised fluidised bed combustion (PFBC) power plants, and 3) the integrated gasification combined cycle (IGCC) power plants.

  3. 7. Streams, Steams, and Steels : A Transnational History of Risk Regulation in Nuclear Power Plants (1850–1985)

    Författare :Siegfried Evens; Per Högselius; Kati Lindström; Anna Storm; Scott Knowles; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Nuclear; risk; water; steam; steel; regulation; safety; Nucléaire; risque; eau; vapeur; acier; sûreté; réglementation; Kärnkraft; risk; vatten; ånga; stål; säkerhet; History of Science; Technology and Environment; Historiska studier av teknik; vetenskap och miljö;

    Sammanfattning : Water is essential to produce nuclear energy and prevent nuclear disasters. As light water reactors are increasingly seen as a solution to achieving a sustainable energy transition and battling the climate crisis, it is more important than ever to investigate the risks of using water for nuclear power production.

  4. 8. Developing Humidified Gas Turbine Cycles

    Författare :Michael Bartlett; KTH; []
    Nyckelord :advanced gas turbine cycles; evaporative; humidified; power; heat and power;

    Sammanfattning : As a result of their unique heat recovery properties,Humidified Gas Turbine (HGT) cycles have the potential todeliver resource-effective energy to society. The EvaporativeGas Turbine (EvGT) Consortium in Sweden has been studying thesetypes of cycles for nearly a decade, but now stands at acrossroads, with commercial demonstration remaining. LÄS MER

  5. 9. Steam Turbine Thermal Modeling for Improved Transient Operation

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

    Sammanfattning : 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. LÄS MER

  7. 10. Advanced power cycles with mixture as the working fluid

    Författare :Maria Jonsson; KTH; []
    Nyckelord :power cycle; mixture working fluid; Kalina cycle; ammonia-water mixture; reciprocating internal combustion engine; bottoming cycle; gas turbine; evaporative gas turbine; air-water mixture; exergy;

    Sammanfattning : The world demand for electrical power increasescontinuously, requiring efficient and low-cost methods forpower generation. This thesis investigates two advanced powercycles with mixtures as the working fluid: the Kalina cycle,alternatively called the ammonia-water cycle, and theevaporative gas turbine cycle. LÄS MER
