  1. 21. Co-combustion of Industrial Biosludge and other Residual Streams in a Bubbling Fluidized Bed : Focusing on reduction of operating and technical problems by analyzing the ash transformation chemistry

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Christian Öberg; [2016]
    Keywords : Co-combustion; biosludge; fluidized bed reactor; corrosion; nutrient recovery;

    Abstract : Today the use of resources in the industry are not complete to be considered as sustainable from the perspective of nutrient recovery. In the Swedish pulp and paper industry residual streams such as bark, fiber reject and sludge are returned for more sustainable use more frequently. READ MORE

  3. 22. A comparative study on twostandardised electrochemicalmethods with emphasis the effectof microstructure and inclusionson pitting corrosion on duplexstainless steel

    University essay from KTH/Materialvetenskap

    Author : Khadijeh Jafari; [2016]
    Keywords : Duplex stainless steel; pitting corrosion; electrochemical test; potentiostatic; potentiodynamic ASTM; inclusion; microstructure; sigma phase; phase arrangement;

    Abstract : Duplex stainless steel (DSS) that developed in the 1930’s is a type of steel that consists of bothaustenite and ferrite phases in an almost equal proportion. It inherits properties of both ferriticand austenitic stainless steel and so it has good mechanical and corrosion resistance propertiesthat makes it suitable material in different industries with aggressive environment.

  5. 24. High temperature corrosion on heat exchanger material exposed to alkali salt deposits

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Kajsa Persson; [2015]
    Keywords : high temperature corrosion; alkali salt; deposits; heat exchanger;

    Abstract : Power generation through decentralized small scale CHP would facilitate the use of biomass as an energy source, with the externally fired gas turbine (EFGT) being a promising technology due to its high electrical efficiency. In an EFGT hot flue gases are heat-exchanged with an air cycle, driving the turbine. READ MORE

  6. 25. Wear of Grate Plates

    University essay from KTH/Materialvetenskap

    Author : Johan Martinsson; [2014]
    Keywords : Grate; plate; wear;

    Abstract : This report describe the wear of the protruding areas on the sides of the grate plates in the grate-kiln process in the hematite pellet production in LKAB, Kiruna. The steel plates are exposed to a hostile environment with heat cycles and corrosive atmosphere. READ MORE
