  1. 1. An analytical method for quickly evaluating the performances of refractory alloys in sCO2 Brayton cycle applications

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Jiaqi Yang; [2023]
    Nyckelord :;

    Sammanfattning : A rapid and effective analytical method has been developed to assess the performance of structural materials in sCO2 power cycle applications. This method combines a conjugate heat transfer model, considering constant heat flux boundary conditions, with a corresponding mechanical model. LÄS MER

  3. 2. Testing of AblativeMaterials as a Protective Coating for Rocket Launch Pads

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Gioele Daka; [2023]
    Nyckelord :Ablative Materials; Protective Coating; Rocket Launchpad; Refractory Materials; Oxyacetylene Torch; Slug Calorimeter; Ablativa material; Skyddande beläggning; Raketstartplatta; eldfast material; acetylensyrebrännare; kopparkalorimeter;

    Sammanfattning : As the space market grows, demand for sites to host rocket tests and to launch satellites to orbit is expected to increase. During these activities, the launch infrastructure needs to withstand the extreme thermal and mechanical loads associated with the exhaust of a rocket engine. LÄS MER

  4. 3. Improving Availability of the Pelletization Process

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Emil Andreasson; Pontus Åhman; [2022]
    Nyckelord :Availability; Predictive Maintenance; Pelletization; Statistical Process Control; Refractory Material; DMAIC;

    Sammanfattning : The Grate-Kiln-Cooler process is a commonly used method of sintering during iron ore pelletization, where the pellets are formed, dried, and hardened. The pellets are oxidized in the rotating Kiln, turning magnetite (Fe3O4) to hematite (Fe2O3), making the pellets attain suitable metallurgical attributes for further processing. LÄS MER

  5. 4. The Impact of Water Addition on the Fracture Toughness of Pre-cast Refractory Materials

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Paulina Lindblad; [2022]
    Nyckelord :refractory materials; pre-cast elements; ceramics; fracture toughness; water addition; porosity; ceramic vortex finder;

    Sammanfattning : A ceramic vortex finder (CVF) is the central pipe (gas outlet) of a gas cyclone, which is an important structural component within gas cyclone separation. Its main application is within high temperature processes, within the energy and cement industry where the atmosphere is highly abrasive and corrosive. LÄS MER
