  2. 21. Modelling elements in conversion of solid fuels - fixed bed combustion and gaseous radiation

    Author : Robert Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combustion; fixed bed; modelling; solid fuels; gas radiation;

    Abstract : For a long heat and power production by combustion of solid fuels has time been an established technique. Environmental concern of emissions for NOx, SOx and other harmful species has caused an increasingly stricter legislation on the emission levels of the boilers. READ MORE

  4. 22. Axial Mixing of Large Solids in Fluidised Beds – Modelling and Experiments

    Author : Anna Köhler; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid-dynamic down-scaling; fluidised beds; magnetic particle tracking; solids mixing; semi-empirical modelling;

    Abstract : Fluidisation is a technology commonly found wherever particulate solids are to be transported, mixed and/or reacted with a gas. At present, it is a widespread technology with applications ranging from the production of carbon nanotubes in the manufacturing industry to the conversion of solid fuels in the heat and power sector.

  5. 23. Fluidized bed combustion - modeling and mixing

    Author : David Pallarès; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluidized bed combustion; Mixing; Modeling;

    Abstract : First demonstrated on industrial scale in 1976, fluidized bed combustion (FBC) rapidly became an established technology for solid fuel combustion with a currentinstalled capacity of about 30 GWe and power plants ranging from 10 to 460 MWe.The widespread use of the FBC technology both under so-called circulating and bubbling conditions (i.e. READ MORE

  6. 24. Modeling of Combustion, Mixing and Heat Transfer in Oxy-Fuel CFB Power Plants

    Author : Sadegh Seddighi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : An important contribution to anthropogenic emissions of CO2 is from electricity generation, i.e. emissions from large fossil fuelled power plants. Carbon Capture and Storage technologies offer the possibility for continued use of fossil fuels while almost eliminating the CO2 emissions. READ MORE

  7. 25. Short- and long-term variability in future electricity systems – Ensuring the flexibility to manage the grid frequency and inter-annual variations

    Author : Jonathan Ullmark; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inter-annual variability; flexibility; frequency control; battery storage; Electricity systems modelling; capacity expansion planning;

    Abstract : To achieve climate mitigation targets, the net climate impact from electricity generation must be drastically reduced in the near future, and eventually eliminated. The level of generation must also be increased to accommodate the increasing demand as the transport and industry sectors undergo electrification. READ MORE
