  2. 1. Corrosion-induced release of zinc and copper in marine environments

    Author : Jan Sandberg; Inger Odnevall Wallinder; Dan Persason; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; copper; zinc; marine environment; runoff rate; atmospheric corrosion; chloride deposition; anti-fouling paints; chemical speciation; bioavailability; cupric ions; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : This licentiate study was initiated by copper, zinc and galvanized steel producers in Europe, who felt a need to assess runoff rates of copper and zinc from the pure metals and commercial products at marine exposure conditions. Their motive was the increasing concern in various European countries and the on-going risk assessments of copper and zinc within the European commission. READ MORE

  4. 2. Fouling in biomass fired boilers

    Author : Jan Sandberg; Rebei Fdhila; Erik Dahlqvist; Alain Liné; Mälardalens högskola; []
    Keywords : Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : This thesis describes a detailed investigation into fouling in biomass fired boilers according to fuel mixture, combustion conditions, transportation of particles by the flue gas and the probability of particles impinging and sticking onto heat transfer tubes. The effects of fouling on overall boiler performance and the efficacy of soot blowing are also investigated. READ MORE

  5. 3. Fouling in biomass fired boilers

    Author : Jan Sandberg; Rebei Bel Fdhila; Erik Dahlqvist; Anders Nordin; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fouling; deposit; boiler; biomass; simulations; Thermal energy engineering; Termisk energiteknik; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : In order to reduce the discharge of the greenhouse gas CO2, the use of biomass is nowadays promoted as fuel in boilers. Compared to boilers fired with coal and oil the biomass-fired boilers have more complications related to both fouling and corrosion on the heat transfer surfaces. READ MORE

  7. 5. Process intensification in mechanical pulping : Reduced process complexity and improved energy efficiency

    Author : Christer Sandberg; Per Engstrand; Jan-Erik Berg; Göran Bengtsson; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This work shows that, for newsprint quality grades, the production processes for mechanical pulp can be simplified, and the specific electrical energy demand can be reduced with around 600 kWh/ton (30%). The purpose of the work is to demonstrate how the production cost for mechanical pulps can be decreased through increased energy efficiency and reduced number of unit operations. READ MORE
