  1. 1. Polygeneration District Heating and Cooling Systems Based on Renewable Resources

    Författare :Natalia Kabalina; Mário Manuel Gonçalves Costa; Weihong Yang; Andrew Martin; Luis Barreiros Martins; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating and cooling systems; polygeneration; refuse derived fuel; municipal solid waste; gasification.; Energy Technology; Energiteknik;

    Sammanfattning : Traditional district heating (DH) and district heating and cooling (DHC) systems have to address two principal challenges: phase-out of fossil fuels in favor of renewables; and profit instability related to declines in heating and cooling demands along with electricity price fluctuations. These obstacles can be overcome at once through upgrading these systems to a polygeneration concept by means of a retrofitted air-steam gasifier and gas upgrading equipment, enabling the use of renewable feedstocks such as refuse derived fuel (RDF) and municipal solid waste (MSW).

  3. 2. Pyrolysis of mixed plastics and paper to produce fuels and other chemicals

    Författare :Nanta Sophonrat; Weihong Yang; Linda Sandström; Tobias Richards; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Mixed plastics and biomass; Cellulose; Refuse derived fuels RDF ; Paper rejects; Interactions; Stepwise pyrolysis; Calcium oxide CaO ; Chemical Engineering; Kemiteknik; Energy Technology; Energiteknik;

    Sammanfattning : As the world population and economy grow, higher consumption results in higher waste packaging, plastics and paper residues. Pyrolysis offers a way to recover fuels and other chemicals from this waste fraction. LÄS MER

  4. 3. Modelling Towards Control of Dynamic Systems : Applications on RDF Fired CFB Performance and DHN Distribution

    Författare :Nathan Zimmerman; Konstantinos Kyprianidis; Carl-Fredrik Lindberg; Erik Dahlquist; Natasa Nord; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat and Power; Circulating Fluidized Bed Boiler; District Heating; Model Predictive Control; Feed-Forward; CHP; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : The combination of global warming along with increasing energy demand necessitates the importance of improving processes pertaining to the production and consumption of energy in combined heat and power plants. This thesis brings to light transient factors currently burdening process performance for circulating fluidized bed boilers (CFBs) combusting refuse derived fuels (RDFs) and district heating networks (DHN).
