1. 26. Experimental Study of Using Butanol or Octanol Blends as Alternative Fuels in Diesel Engines

   Författare :Tankai Zhang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : With the increased travel demand, the consumption of fossil fuels, as the main energy source for transportation, has risen sharply over the last few decades. Fossil fuels are considered a non-renewable resource. In addition, burning them in internal combustion engines can generate a large amount of greenhouse gas (GHG) emissions. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

5. 29. Chemical Transformation of Inorganic Species in Thermochemical Conversion of Waste-Derived Fuels - The Role of Oxygen Carriers

   Författare :Ivana Stanicic; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxygen carriers; Waste-derived fuels; thermodynamic equilibrium calculations; heavy metals; chemical looping;

   Sammanfattning : Waste-derived fuels are used increasingly in heat and power production systems in Sweden. Thermal conversion of waste-derived and biomass fuels offers the possibility of achieving carbon dioxide-neutral or even negative emissions. To limit global warming, it is essential to integrate these systems with carbon capture and storage. LÄS MER

7. 30. Thorium fuels for light water reactors - steps towards commercialization

   Författare :Klara L Insulander Björk; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Halden research reactor; light water reactors; fuel performance; plutonium; Thorium; neutronic simulations;

   Sammanfattning : Thorium-containing nuclear fuel is proposed as a means of gaining a number of benefits in the operation of light water reactors, some related to the nuclear properties of thorium and some related to the material properties of thorium dioxide. This thesis aims to investigate some of these benefits and to widen the knowledge base on thorium fuel behaviour, in order to pave the way for its commercial use. LÄS MER
