  1. 1. Household waste collection : factors and variations

    Author : Lisa Dahlén; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : Ambitious household waste recycling programs have been introduced in Sweden and several other countries during recent decades. Many different waste- sorting and collection schemes have been developed, but the evaluation and comparison of the results is made difficult by the lack of comparable data. READ MORE

  2. 2. Contamination in Swedich waste wood : environmental implications, sources and waste management strategies

    Author : Joakim Krook; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Today, bulk materials, e.g. wood, plastic, steel, and concrete, are contaminated by hazardous substances such as heavy metals, causing environmental and resource problems during waste management. READ MORE

  3. 3. Superheater corrosion in biomass and waste fired boilers : Characterisation, causes and prevention of chlorine-induced corrosion

    Author : Peter Viklund; Christofer Leygraf; John Nicholls; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high temperature corrosion; waste; biomass; superheater tubes; steel; alkali; chlorine; sulphur;

    Abstract : Biomass and waste fired boilers suffer severely from corrosion of critical components such as superheater tubes. In this work high temperature corrosion of superheater alloys, and methods to mitigate the problem, have been investigated by laboratory studies and controlled field exposures in commercial boilers.

  4. 4. The Corrosive Effect of Chlorine Containing Species on Waterwalls and Superheater Materials in Waste and Biomass-Fired Power Plants

    Author : Erik Larsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; Sulfur recirculation; Superheater corrosion; Heavy metal chlorides; Waterwalls; Alkali-induced corrosion; Biomass; Waste;

    Abstract : To increase power generation from waste- and biomass-fired boilers, it is necessary to increase the temperature and pressure of the steam generated. This implies an increase in the temperature both of the waterwalls and of the steam superheaters in the boiler. READ MORE

  5. 5. Catalytic combustion of gasified waste

    Author : Henrik Kusar; KTH; []
    Keywords : Catalytic combustion; Gasified waste; LHV-fuel; RDF; Biomass; Selective catalytic oxidation; NH3; NOX; Palladium; Platinum; Hexaaluminate; Garnet; Spinel; Deactivation; Sulphur; Poisoning;

    Abstract : This thesis concerns catalytic combustion for gas turbineapplication using a low heating-value (LHV) gas, derived fromgasified waste. The main research in catalytic combustionfocuses on methane as fuel, but an increasing interest isdirected towards catalytic combustion of LHV fuels. READ MORE
