1. 6. Efficiency Improvements in Waste-to-Energy Combustion Processes : Method Development and Evaluation

   Författare :Eboh Francis Chinweuba; Simon Harvey; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid waste; exergy; entropy; higher heating value; improvement potential; waste-to-energy plant; efficiency improvement; cost evaluation; simulation; modelling; Resource Recovery; Resursåtervinning;

   Sammanfattning : is the energy recovery method. The electrical efficiency of this technology, however, is generally low when compared with other solid fuel-fired combustion plants as a result of low steam properties. Furthermore, there is lack of efficient methods to evaluate the performance of this system. LÄS MER

   Sammanfattning : Industrial energy efficiency improves the profit and competitive advantage of companies. The pulp and paper industry (PPI)being one of the five most energy-intensive industries uses 5.6% of global industrial energy, according to the InternationalEnergy Agency. LÄS MER

4. 8. Industrial energy efficiency improvement – the role of policy and evaluation

   Författare :Christian Stenqvist; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement.; Pulp and paper; Decarbonisation; EU ETS; Energy management; Voluntary Agreement; Evaluation; Policy; Industrial energy efficiency;

   Sammanfattning : At EU and to a varying degree at Member State (MS) level, industrial energy efficiency improvement (EEI) is considered an attractive means for reaching political objectives of different dimensions, not least environmental. For energy-intensive manufacturing industry in particular, EEI can lead to cost reductions, improved profitability and competitiveness. LÄS MER

5. 9. Low temperature deicing of road infrastructure using renewable energy

   Författare :Josef Johnsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; borehole thermal energy storage; renewable energy; BTES; numerical simulations; Pavement solar collector; Hydronic heated pavements;

   Sammanfattning : Winter road maintenance is costly but it is inevitable since it is necessary to keep roads accessible and safe during winter. Current winter road maintenance methods use annually 600 000 tons of salt, in the Nordic countries. The salt ends up in the environment along the roads and results in environmental challenges.
