  1. 1. Phasing out peat from a co-fired 50 MWth circulating fluidized bed boiler : A theoretical sulfation potential study

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

    Author : Axel Bergstrand; [2022]
    Keywords : Peat; corrosion; fuel mixture; CFB; circulating fluidized bed; S; alkali chlorides; Sulfur; additives; combustion; fuel design; alkali related corrosion;

    Abstract : The chemical company Perstorp AB has a 50 MWth circulating fluidized bed to supply the production plant with process steam. The fuel mixture used shows a large variation with about 20 different fuel fractions that can be divided into the categories, residue wood chips, sludge, forest fuel, animal waste, industrial residues, and peat.

  3. 2. Corrosion protection of aluminum coated with a polymer matrix in presence and absence of conductive polymer

    University essay from KTH/Ytbehandlingsteknik

    Author : Mohamed Hassan Abdi; [2021]
    Keywords : Corrosion protection; Barrier coating; Conductive polymer; Electrochemical impedance spectroscopy; Atomic force microscopy; Korrosionsskydd; Barriär beläggning; Ledande polymer; Elektrokemisk impedans spektroskopi; Atomkraftmikroskopi;

    Abstract : Aluminium och aluminiumlegeringar har ganska bra korrosionsbeständighet, men dessa material kan fortfarande korrodera. Metallkorrosion är aldrig önskvärt och det kan leda till katastrofala resultat i olika branscher och applikationer. READ MORE

  4. 3. Design of passively loaded specimen for constant KI during crack growth

    University essay from KTH/Hållfasthetslära

    Author : Liisa Tofferi; [2021]
    Keywords : constant KI; passively loaded specimen; konstant KI; passivt belastad provstav;

    Abstract : Passive loading of a specimen is a relatively cheap method to use in fracture mechanical testing compared to an actively loaded specimen. For stress corrosion cracking testing it is easier to use a passively loaded specimen since the specimen easily can be placed in a specific corrosive environment. READ MORE

  5. 4. Corrosion of additively manufactured magnesium alloy WE43 : An investigation in microstructure and corrosion properties of as built samples manufactured with Powder Bed Fusion-Laser Beam

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Clarence Wahman; [2021]
    Keywords : Mangesium; WE43; corrosion; additive manufacturing; biodegradable implants; microstructure; surface roughness; Magnesium; WE43; korrosion; additiv tillverkning; resorberbara implantat; mikrostruktur; ytråhet;

    Abstract : The work presented in this thesis was conducted at Uppsala University and at Swerim AB. The study aims to broaden the knowledge about the corrosion of additively manufactured bioresorbable alloy WE43 in humanlike conditions for future applications. READ MORE

  6. 5. Design and development of an automated rat trap for sewage system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Vallabh Venkatachalam; [2021]
    Keywords : Rat trap; automated trap; sewage systems; mechanical rat trap; Råttfälla; automatiserad fälla; avloppssystem; mekanisk råttfälla;

    Abstract : This thesis report describes the design and development of an automated rat trap for sewage system. This rat trap has been designed to have a working duration of 2 months or approximately 15749 hits with trap dimensions length 535 mm, width 430 mm and a height range of 931 – 1151 mm with respect to different sewer pipe diameters.
