  1. 6. Feasibility study for a 300kW pilot scale hydrogen production process from wood biomass : The case of Sandviksverket, Växjö

    University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Author : Derick Samjeila Ewang; [2020]
    Keywords : Hydrogen; Biomass; Pyrolysis; Gasification; Combustion.;

    Abstract : Historically, fossil fuel sources (coal, oil and natural gas) have played significant role in meet global energy demand. As global population continue to rise, more and more energy resources are needed and there is a continuous depletion of these energy resources. READ MORE

  3. 7. Performance evaluation of ground source heat pump heating systems in Stockholm

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

    Author : MARCUS BÖRJESSON; [2020]
    Keywords : Ground source heat pump system; GSHP system; vertical borehole; ground heat exchanger; BHE; EED; evaluation; COP; SPF; Ideal temperature dependent SPF; temperature dependent SPF efficiency; SEPEMO; Sweden; Bergvärmesystem; borrhål; kollektor; EED; utvärdering; COP; SPF; ideal temperaturberoende SPF; temperaturberoende SPF-verkningsgrad; SEPEMO; Sverige;

    Abstract : GSHP systems are common in Sweden but there are few evaluations quantifying the performance of the systems and highlighting problem that occurs during operations. The research project Annex 52 Long-term performance measurement of GSHP systems serving commercial, institutional and multifamily building part of IEA HPT TCP proves the need to systematically be able to evaluate GSHP systems.

  4. 8. Secondary Steel Metallurgy Slag Design and MgO-C Refractory Implications : Theoretical and Practical Considerations

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Hellgren Simon; [2019]
    Keywords : MgO-C; CaO-SiO2-Al2O3-MgO; Slag Design; Refractory Wear;

    Abstract : MgO-C based refractory materials, often used in secondary steel making, are exposed to variouswear mechanisms in its application. The wear could be divided into oxidative, chemical andabrasive categories, all behaving differently and all being influenced by different factors. READ MORE

  5. 9. Modelling heat recovery from urban wastewater systems - case study from Malmö

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Diego Reyes; [2019]
    Keywords : Heat; Recovery; Wastewater; City; Wide; Model; Urban; Sustainability; Sewer; System; Malmo; Temperature; Sweden; Water engineering; Environmental engineering; Vattenförsörjningsteknik; Avloppsteknik; Technology and Engineering;

    Abstract : The purpose of this thesis is to estimate how much heat can be recovered from the sewer system in Malmö, Sweden, and determine the best location for that heat recovery. In fulfilling that purpose, this thesis covers the process of modeling wastewater flows and temperature changes in the sewer system in Malmö, the results of those processes, and the estimated amount of heat that can be recovered from the sewer system.

  6. 10. Monitoring of a heat pump system using deep borehole heat exchangers

    University essay from KTH/Energiteknik

    Author : Baptiste Delattre; [2018]
    Keywords : ;

    Abstract : Sweden has been one of the first countries in the world to use ground-source heat pumps (GSHP) to supply heating and cooling to its buildings. Today, it is the leading country in Europe and new installations tend to have larger capacities. READ MORE
