  2. 1. Some Aspects of Gas Turbine Fuel Preparation and Turbomachinery Response to LCV Fuels

    Author : Pontus Eriksson; Kraftverksteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PDA; LDA; PIV; atomization; spray; off-design; biogas; combustor; biofuel; turbine; Gas turbine; compressor;

    Abstract : This thesis gives some background information on environmental issues as the scientific community at large currently sees it. It tries to relate the plethora of current combustion technologies which may be used in gas turbines to those issues. Some basic principles on combustion design are given. READ MORE

  4. 2. Operational stability of lean premixed combustion in gas turbines : an experimental study on gaseous alternative fuels

    Author : Parisa Sayad; Kraftverksteknik; []
    Keywords : Premixed Combustion; Syngas; Swirl Stabilized; Chemical Kinetics; Flashback; Lean Blowout; Autoignition; OH*-chemiluminescence;

    Abstract : World electricity consumption is drastically increasing. One of the most common ways of producing electricity is to use the chemical energy of fossil fuels. This can be done in thermal power plants in which the chemical energy of fossil fuels such as natural gas is converted to mechanical energy and finally to electricity. READ MORE

  5. 3. Hydrogen in the European energy system - The cost dynamics and the value of time-shifting electricity generation

    Author : Simon Öberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost; energy systems modeling; Hydrogen; gas turbine; system dynamics; time-shifting;

    Abstract : If the European Union is to become climate-neutral by Year 2050, as envisioned in the European Green Deal, the European energy system must undergo an unprecedented transformation towards eliminating its carbon emissions. For this transition, renewable electricity plays a central role, not only in replacing the current fossil-based electricity generation, but also in promoting the electrification of other sectors, such as transport and industry, sectors which are currently based on fossil fuels.

  6. 4. Efficiency of heat and work in a regional energy system

    Author : Tommy Rosén; Louise Ödlund; Shahnaz Amiri; Erik Dotzauer; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : One of the largest flows of energy in Swedish municipalities is the fuel-energy flow through the regional combined heat and power (CHP) plant. The customer products from this flow are mainly electricity to the electricity grid and heat to the building sector. READ MORE

  7. 5. Functional nanocomposites for advanced fuel cell technology and polygeneration

    Author : Rizwan Raza; Bin Zhu; Torsten Fransson; Mahmut D. MAT; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polygeneration; advanced fuel cell; functional materials; ceria-carbonate nanocomposites; multi-fuelled; electrolyte free fuel cell; SRA - Energy; SRA - Energi;

    Abstract : In recent decades, the use of fossil fuels has increased exponentially with a corresponding sharp increase in the pollution of the environment. The need for clean and sustainable technologies for the generation of power with reduced or zero environment impact has become critical. READ MORE
