  1. 21. Thermoeconomic Analysis and Optimisation of Air-Based Bottoming Cycles for Water-Free Hybrid Solar Gas-Turbine Power Plants

    University essay from KTH/Kraft- och värmeteknologi

    Author : Raphael Sandoz; [2012]
    Keywords : ;

    Abstract : The growing worldwide energy demand and the impacts of climate change due to anthropogenic greenhouse gases emissions are among the major issues facing humanity. The global energy system, responsible for most of the greenhouse gases emissions, is therefore at the heart of global concerns. READ MORE

  3. 22. Energy and cost analysis of household electricity efficiency improvements in a rental apartment building

    University essay from Institutionen för teknik och hållbar utveckling

    Author : Manaswita Panigrahi; [2012]
    Keywords : household electricity; energy efficiency; cost analysis; CO2 emissions;

    Abstract : In this thesis potential for (final and primary) energy and CO2 emission reductions and cost effectiveness of replacing existing household electric appliances and light bulbs with most popular or most energy efficient appliances in a multifamily apartment building in Växjö city is studied. The results showed that there is significant potential to reduce electricity demand and thereby to reduce primary energy use and CO2 emissions. READ MORE

    Abstract : The development in the steam turbine business is heading for applications with much higher steam parameters since this enables a raised efficiency. Steam parameters refer to the pressure and the temperature of the steam. READ MORE

  6. 25. Thermodynamic modelling of biomass based power production

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Emil Bjäreborn; Fredrik Åkerman; [2010]
    Keywords : biomass fuels gas turbine steam cycle; Technology and Engineering;

    Abstract : With today’s growing awareness of human caused climate changes there is a big interest to replace fossil fuels with renewable fuel sources, such as biomass fuels. For power production biomass are traditionally combusted in small scale facilities which uses a steam cycle. The electrical efficiencies for such facilities are relatively low. READ MORE
