  1. 1. Gasification and Pyrolysis Characterization and Heat Transfer Phenomena During Thermal Conversion of Municipal Solid Waste

    Author : Chunguang Zhou; Weihong Yang; Wlodzimierz Blasiak; Petr Stehlik; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; municipal solid waste; pyrolysis; gasification; heat transfer; CaO; CO2; reforming; numerical model; Energiteknik; Energy Technology; Chemical Engineering; Kemiteknik;

    Abstract : The significant generation of municipal solid waste (MSW) has become a controversial global issue. Pyrolysis and gasification technologies for treating rejects from solid waste disposal sites (SWDSs), for which over 50 % of MSW is attributed to combustible species, have attracted considerable attention.

  2. 2. Mathematical modeling of municipal solid waste plasma gasification in a fixed-bed melting reactor

    Author : Qinglin Zhang; Weihong Yang; Wlodzimierz Blasiak; Halina Kruczek; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mathematical modeling; plasma gasification; municipal solid waste; fixed-bed;

    Abstract : The increasing yield of municipal solid waste (MSW) is one of the main by-products of modern society. Among various MSW treatment methods, plasma gasification in a fixed-bed melting reactor (PGM) is a new technology, which may provide an efficient and environmental friendly solution for problems related to MSW disposals.

    Abstract : Waste-management systems have progressed from landfilling and dumping to waste prevention, recycling and resource recovery. In state-of-the-art waste-management industries, waste is separated into various fractions and treated with suitable processes. READ MORE

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

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

    Abstract : 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).

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

    Author : Eboh Francis Chinweuba; Simon Harvey; Högskolan i Borås; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    Abstract : 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. READ MORE
