  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. Phasing out identities? Narratives of coal workers’ struggles in Lusatia’s energy transition process

    University essay from Lunds universitet/Humanekologi; Lunds universitet/Kulturgeografi och ekonomisk geografi

    Author : Nele Buchholz; [2021]
    Keywords : coal phase-out; workers’ rights; political ecology; just transition; social dimensions of energy transitions; energy epistemics; energy landscapes; energy justice; energy identity; narrative research; Germany; Lusatia; Social Sciences;

    Abstract : In 2020, the German government introduced a legislation to phase-out coal mining and combustion by 2038. Expert reports state that this is too late for Germany to meet its obligations from the Paris Agreement. For many people in Lusatia, one of the three coal mining areas in Germany, even the 2038 coal-exit is happening too fast. READ MORE

  4. 3. Knock model evaluation - Gas engine

    University essay from KTH/Förbränningsmotorteknik

    Author : Nishchay Sharma; [2018]
    Keywords : Knocking; Spark-Ignited; Internal Combustion Engine; Spark-Knock; Empirical Correlation Models; BOOST; Combustion Phasing; Spark-advance; Combustion Duration; Knock Prediction Parameter.; Knack; Otto-förbränning; Förbränningsmotor; Empiriska korrelationsmodeller; BOOST; Förbränningsfasning; Tändvinkel; Förbränningsduration; Knackprediktering;

    Abstract : Knack i en förbränningsmotor är en typ av onormal förbränning. Det är ett komplicerat fenomen som beror på flera fysiska faktorer och resulterar i högfrekventa tryckoscillationer inuti förbränningskammaren. Dessa oscillationer kan skada motorn och fenomenet hämmar motorns effektivitet. READ MORE

  5. 4. Estimation of Air Mass Flow in Engines with Variable Valve Timing

    University essay from Linköpings universitet/Reglerteknik

    Author : Elina Fantenberg; [2018]
    Keywords : Diesel Engine; Variable Valve Timing; Air Mass Flow;

    Abstract : To control the combustion in an engine, an accurate estimation of the air mass flow is required. Due to strict emission legislation and high demands on fuel consumption from customers, a technology called variable valve timing is investigated. READ MORE

  6. 5. Knock Model Evaluation – Gas Engine

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : Nishchay Sharma; [2018]
    Keywords : Knocking; Spark-Ignited; Internal Combustion Engine; Spark-Knock; Empirical Correlation Models; BOOST; Combustion Phasing; Spark-advance; Combustion Duration; Knock Prediction Parameter.; Knack; Otto-förbränning; Förbränningsmotor; Empiriska korrelationsmodeller; BOOST; Förbränningsfasning; Tändvinkel; Förbränningsduration; Knackprediktering.;

    Abstract : Knocking is a type of abnormal combustion which depends on several physical factors and results in high frequency pressure oscillations inside the combustion chamber of a spark-ignited internal combustion engine (ICE). These oscillations can damage the engine and hamper its efficiency, which is why it is important for automakers to understand the knocking behavior so that it can be avoided during engine operation.
