1. 6. Retrofitting CHP Plant and Optimization of Regional Energy System

   Författare :Song Han; Jinyue Yan; Eva Thorin; Mats Westermark; Mälardalens högskola; []
   Nyckelord :annual performance; combined heat and power; drying; ethanol; integration; part-load.; årliga prestation; kraftvärme; torkning; etanol; integration; del-last.; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : The use of biomass-based combined heat and power (CHP) plants is considered by the EU administration to be an effective way to increase the use of renewables in the energy system, to reduce greenhouse gas emissions and to alleviate the dependency on imported fossil fuels. At present in Sweden, most of the CHP plants are operated in part-load mode because of variations in heat demand. LÄS MER

3. 7. On the value of land

   Författare :Stefan Hellstrand; Jinyue Yan; Pontus Cerin; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : The issue of sustainable development is once again moving the production factor land into the focus of economic theory and practise. There are three production factors, capital, labour and land. Land is a synonym to ecosystems. During the major part of the 20th century land in economic theory has been handled as a peripheral issue. LÄS MER

4. 8. CO2 capture from oxy-fuel combustion power plants

   Författare :Yukun Hu; Jinyue Yan; Erik Dahlquist; Mats Westermark; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; oxy-fuel combustion; flue gas recycle; evaporative gas turbine; techno- economic evaluation;

   Sammanfattning : To mitigate the global greenhouse gases (GHGs) emissions, carbon dioxide (CO2) capture and storage (CCS) has the potential to play a significant role for reaching mitigation target. Oxy-fuel combustion is a promising technology for CO2 capture in power plants. LÄS MER

5. 9. Oxy-coal combustion and its integration with power systems for CO2 capture

   Författare :Yukun Hu; Jinyue Yan; Roland Span; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxy-coal combustion; flue gas recycle; radiation; peak and off-peak operations; cryogenic CO2 purification;

   Sammanfattning : Oxy-fuel combustion is one of the technologies for carbon dioxide (CO2) capture and storage (CCS) in fossil fuel based power systems to mitigate global greenhouse gases (GHGs) emissions. When introducing oxy-fuel combustion into the power systems, energy penalty for CCS has significant impacts on the system performance. LÄS MER

7. 10. Thermodynamic properties of humid air and their application in advanced power generation cycles

   Författare :Xiaoyan Ji; Jinyue Yan; Umberto Desideri; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air-water mixture; humid air; properties; wet cycles; dry air; water; enthalpy; entropy; heat capacity; density; evaporative gas turbine; compressed air energy storage; Chemical engineering; Kemiteknik;

   Sammanfattning : Water or steam is added into the working fluid (often air) in gas turbines to improve the performance of gas turbine cycles. A typical application is the humidified gas turbine that has the potential to give high efficiencies, high specific power output, low emissions and low specific investment. LÄS MER
