  1. 1. Parametric investigation of a theoretical organic rankine cycle

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Jim Wernersson; [2023]
    Keywords : ;

    Abstract : The energy resource waste heat or low-grade thermal energy is available in vast quantities. Tapping into this resource and converting it to electrical energy would not only reduce energy waste but also has the potential to eliminate greenhouse gas emissions. READ MORE

  3. 2. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

    University essay from KTH/Materialvetenskap

    Author : Hagen Christian Hagens; [2022]
    Keywords : Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

    Abstract : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. READ MORE

  4. 3. Review and Design Adaptations of a SrCl2-NH3 bench-scale Thermochemical Heat Storage system

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

    Author : Hjörtur Brynjarsson; [2021]

    Abstract : Thermochemical heat storage (TCS) is a thermal energy storage (TES) technology used to store thermal energy for later use. TCS can provide heating or cooling services from intermittently available thermal energy, often low grade waste heat. READ MORE

  5. 4. High Resolution Mapping and Spatial Analysis of Carbon Free Heat Sources for District Heating : A Case Study of Helsinki

    University essay from KTH/Energiteknik

    Author : Filip Norrman; Mattias Persson; [2021]
    Keywords : High-­Resolution Mapping; Carbon-­Free Heat Sources; 4th Generation District Heating; GIS; Hög­upplöst kartläggning; Koldoixidfria värmekällor; 4e generationen Fjärrvärme; GIS;

    Abstract : Heat production together with electricity production stands for 31% of the global CO2 emissions. The production is as of today still highly dependent on fossil fuels, with a global district energy mix share of fossil fuels of 90%. READ MORE

  6. 5. ORC systems for small scale energy production : Improving the prediction of electricity production of ORC turbines under varying loads

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Kristina Pettersson; [2021]
    Keywords : ;

    Abstract : In order to have a sustainable, resource-efficient energy system and no net emissions of greenhouse gases by 2050, energy efficiency is one important aspect to reach this goal and develop a long-term sustainable energy system. As part of a solution to increase energy efficiency in society, Organic Rankine Cycle (ORC) systems can have a far reaching effect by utilizing low-grade heat to produce electricity. READ MORE
