  1. 1. Techno-Economic Analysis of Organic Rankine Cycles for a Boiler Station : Energy system modeling and simulation optimization

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Jamel Hudson; [2019]
    Nyckelord :Organic Rankine cycle; ORC; Working fluids; Boiler station; District heating system; Simulation model;

    Sammanfattning : The Organic Rankine Cycle (ORC) may be the superior cycle for power generation using low temperature and low power heat sources due to the utilization of high molecular mass fluids with low boiling points. They are flexible, simple, easy to operate and maintain, and offer many possible areas of applications including waste heat recovery and power generation from biomass, geothermal and even solar energy.

  3. 3. Perspectives for Power Generation fromIndustrial Waste Heat Recovery

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

    Författare :Fanny Blanquart; [2017]
    Nyckelord :;

    Sammanfattning : This thesis work was carried out at Siemens in Germany in the department of Steam Turbines, and aims to raise awareness of the potential for broader deployment of waste heat recovery (WHR) from industrial processes for power generation. Technologies available to recover heat are presented and sorted out according to the features of the heat source. LÄS MER

  4. 4. Rankine Cycles, Modeling and Control

    Master-uppsats, Lunds universitet/Institutionen för Energivetenskaper

    Författare :Ylva Teleman; [2016]
    Nyckelord :dynamic; modeling; organic rankine cycles; Modelica; simulation; Dymola.; Rankine cycles; Technology and Engineering;

    Sammanfattning : As the demand for decreased use of energy increases, new ways of using energy sources are investigated. One of these ways is to be able to use low temperature heat sources, which can be done with a rankine or organic rankine cycle. LÄS MER

  5. 5. Elproduktion från lågvärdig spillvärme med ny teknik; ECT-processen : Modellering och jämförelse med Organic Rankine Cycle


    Författare :Sarah Larsson; Tamara Dragic; [2016]
    Nyckelord :;

    Sammanfattning : The constantly growing population in the world is putting more and more pressure on the earth and its natural resources. Meanwhile, the use of fossil fuels keeps creating carbon dioxide emissions that accelerates the global warming. LÄS MER
