Teoretisk analys och praktisk försök
The thesis describes a completely new biofuel system to generate particle-free heat from combustion of ash-containing biofuel particles at high temperatures. The suggested system gives opportunities to introduce biofuels in new areas. Main components in the suggested system is a …
… the economic feasibility of replacingForsmark’s 3rd nuclear reactor with a bio fueled power plant, and find out how this could bedone.The power generation that has to be replaced is equal to 1170 MWe. To replace this, 6 largescaleCFB-boilers, each providing over 200 MWe, were …
… combination with solar energy; Geothermal heating, long- distance heating and bio energy heating. The result of text study shows that the design of the heating system should be installed with an accumulation tank as a central component for distribution of heat. The positioning …
en jämförelse med en minskning av svinnet
… The amount of energy that can be generated through optical sorting and biogas production via anaerobic digestion in downtown Stockholm is 29-44 TJ/year, compared to 118 TJ/year saved by completely eliminating food waste. The generated biogas can replace fossil fuels, but the …

… an environmental perspective. Sack-paper is a very strong paper, that with a bio- degradable coating can be made completely waterproof. The project was made in collaboration with the paper pro- ducer Billerud, which has provided access to materials and knowledge of the subject …
… was used to collect data. The results have been analyzed in Wufi Bio which showed that the moisture content should be somewhere between 12.5 to 18.5%, depending on how the wall is built. The conclusions are that windbreaks vapor resistivity is essential for what is a reasonable …
soil carbon and yield modelling for crop rotations with rye
… in four different cultivation scenarios ? Straw left on the field, biogas digestate added as fertilizer. Labelled ”+straw+BD”. ? Straw left on the field, only synthetic fertilizer. Labelled ”+straw-BD”. ? Straw harvested, biogas digestate added as fertilizer. Labelled …
etanol som fordonsbränsle
According to the EC fuel regulations 2 % bio fuel has to be blended in all fuel by the year 2005, and 5.75 % by the year 2010, which means ethanol for gasoline driven vehicles, so there will be a substantial demand for ethanol. Brazil already has an established industry for …
… treatment processes. One of the aerobic treatment processes includes enhanced biological phosphorus removal (EBPR or Bio-P) as the method for the removal of phosphorus. In biological phosphorus removal the wastewater is alternately being exposed to anaerobic and aerobic …
… to a mix of different power sources. Examples of these commodities are pure bio electricity, pure hydro electricity, pure wind electricity and gray electricity. Gray electricity is an unspecified mix of different power sources where origin does not matter. The aim of this thesis …
… for estimation of air quality in regions with small-scale combustion of bio fuel has been developed by Swedish Meteorological and Hydrological Institute with financing from Swedish Energy Agency and Swedish Environmental Protection Agency. The model contains user interface and a …
… where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient …
Mediumstor bulkförvaringslösning
… thesis was done for a company called BRUKS which is active in woodprocessing, bio-energy and bulk material handling industry. The idea for the master thesis was to develop a new reclaiming method for silos where wood chips are being stored. A medium segment of between 1000 ? …
Future support to biogas production in Sweden
… och utökad produktion, distribution samt användning av förnybara gaser såsom biogas. Myndigheten har samtidigt fått i uppdrag att utveckla en sektorsövergripande biogasstrategi och föreslå åtgärder som på kort och lång sikt kan bidra till ökad användning av biogas. Denna …
… power and heating plant and about 99, 5 percent of their fuel consisted of bio energy in year 2009 (ENA Energi, 2011, länk A). The main purpose with this report is to look at three questions: 1. How does the supply chain look today? From forest to industry. 2. Identify …
