1. 21. Biomass gasification in fluidized bed gasifiers : Modeling and simulation

   Författare :Guilnaz Mirmoshtaghi; Erik Dahlquist; Jan Brandin; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Using woody biomass as a resource for production of biofuel, heat and power through gasification has been studied for years. In order to reduce the cost of operating and to design the full-scale gasification plant developing a general model to be applicable for different ranges of input data with acceptable level of accuracy, is needed.

3. 22. Energy Efficiency in the Residential, Service and Energy Sectors : Barriers, Drivers and System Studies

   Författare :Stefan Blomqvist; Louise Ödlund; Patrik Rohdin; Erik Dahlquist; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Efficiency; Barriers; Drivers; System Studies;

   Sammanfattning : Increased energy efficiency is a prerequisite for achieving the national energy and climate goals, the goals set by the European Union, and the Sustainable Development Goals adopted by the United Nations. Close to 40% of Sweden’s total energy use and approximately 20% of domestic greenhouse gas emissions are allocated to the residential and service sector. LÄS MER

   Sammanfattning : Today’s biomass-fired combined heat and power (CHP) plants have surplus heat production capacity during warmer times of the year. In order to allow them to increase their electricity production, it is essential to find a use for the surplus heat. LÄS MER

7. 25. Conceptual Thermodynamic Cycle and Aerodynamic Gas Turbine Design - on an Oxy-fuel Combined Cycle

   Författare :ADRIAN NILSSON DAHLQVIST; Kraftverksteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas turbine; combined cycle; conceptual design; aerodynamic; mid-span design; through-flow design; oxy-fuel; SCOC-CC; OCC; gas turbine; Combined cycle; conceptual design; aerodynamic; mid-span design; Through-flow design; Oxy-fuel; SCOC-CC; OCC;

   Sammanfattning : The world is today facing a serious problem with global warming, which is heading towards an appallingly high temperature level. The greater part of the overall climate science community agree that global warming is caused by the greenhouse effect, which depends largely on emitted CO2 emissions from the combustion of fossil fuel.
