6. Gårdsbaserad uppgradering av biogas med askfilter
L3-uppsats, SLU/Dept. of Energy and TechnologySammanfattning : Most of the biogas produced in small scale biogas plants in Sweden today is used for combined heat and power production. With the price of electricity being relatively low, the small biogas plants are hardly profitable. LÄS MER
7. Design of a rotary valve for pressurised steam
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : Denna rapport är gjord på ett examensarbete som var utfört på uppdrag av det svenska företaget Ranotor AB. Syftet var att utveckla en konceptuell lösning för en rotationsventil som skall fungera i en miljö med hög temperatur och högt tryck. Ventilen skall arbeta under höga rotationshastigheter, vilket kräver korta öppettider. LÄS MER
8. Isothermal Oxidation Study of Gd2Zr2O7/YSZ Multi-Layered Thermal Barrier Coatings
Magister-uppsats, Högskolan Väst/Avd för tillverkningsprocesserSammanfattning : Conventional yttria stabilized zirconia (YSZ) are widely used in the gas turbine to protect the substrate material from high temperature. But the common YSZ top coatings have limitations at higher temperature (above 1200 ℃) due to significant phase transformation and intensified sintering effect. LÄS MER
9. CFD INVESTIGATION OF THE PURGE AIR INFLUENCE ON THE FLOW STRUCTURE AND BEHAVIOUR OF GAS TURBINE STAGE AND ROTOR-STATOR DISC CAVITY SYSTEM
Master-uppsats, KTH/Kraft- och värmeteknologiSammanfattning : Gas turbines operate with medium of very high temperatures, which requires using advanced materials for vanes and blades and sophisticated methods of their cooling. Other parts of the turbine have to be protected from contact with hot gases. Discs that hold vanes and blades are especially exposed to this danger. LÄS MER
10. Energy analysis of a fruit drying plant in Adeiso, Ghana
L3-uppsats, SLU/Dept. of Energy and TechnologySammanfattning : The purpose of the project has been to work out recommendations that reduce the energy-related costs and environmental impact of HPW Fresh & Dry Ltd., a fruit drying factory in Ghana. The factory produces electricity with diesel and biogas but also purchases electricity from the national electricity company. LÄS MER
