… the selection of electricity mix in the production of district heating, biomass fuel in single-family houses and efficiency in boilers and burners are practically insignificant in the final result.
… kvalitet på ensilaget, samt att jämföra variationen i näringsvärde och mängd biomassa inom och mellan olika fält. Arbetet är baserat på dels egna praktiska moment, där provklippningar har genomförts före första skörd på åtta fält på Ersmarksgården AB, Skellefteå Kommun. Före …
- med fokus på Organisk RankineCykel (ORC)
… combined heat and power techniques, based on combustion of solid moist biomass, which are suitable to small-scale applications. The technique must be able to produce between 2 and 10 MW thermal and the heat demand is a Swedish district-heating system. When already published …
… production was compared to the effects of refined starch addition. The bulk biomass fuel raw material, to which the additive was added, was a blend of spruce and pine sawdust. An experimental design in the factors cassava/starch content, moisture content and material temperature …
… It is, however, possible that there will be an increased competition for biomass in the long run, because of new and expanded application areas for biomass, such as transportation fuel, bio plastic material, etc. The district heating sector is completely dependent on …
… oil has been extracted from the algae, biogas is produced from the residual biomass by anaerobic digestion and then the electricity that can be produced is supplied to the production of biodiesel. When the oil is converted into biodiesel it also produces glycerine that has …
Summary Today energy prices are rising. As a result biomass fuel is getting more and more interesting. Wood chips is very popular, but also straw from grain production is on the table. Lunds Energi AB project a combined power and heating plant in Örtofta out of Lund. Wood chips …
beskrivning av övergödningsproblematiken samt optimering av en reningsmetod genom skörd av vattenväxter
… production. The amount of nutrients that can be removed by harvesting the biomass depends on the amounts of biomass and the nutrient content of it, which in turn is strongly dependent on the nutrient concentration of the surrounding water. Vegetation suggested in the study for …
… Borkh. ”Rubinola”) were used in the experiments in which shoot production and biomass production were studied at different concentrations of cytokinin, auxin and gibberelin. The results were compared with results from the same plant types grown on solid agar-based medium. The …
Ethanol produced from lignocellulosic biomass has the potential to become a promisingalternative to gasoline. In this work the simultaneous saccharification and fermentation (SSF)technology was applied for ethanol production from hardwood with focus on cell growth,ethanol …
… that can be produced. New functions have been developed that estimate the biomass of branches and needles from stand variables. The new functions have been applied on a selection from Sveaskog´s inventory together with a model that estimates the amount of fuel collected in …
… done in five stands. In one of the stands a time study and a measure of stump biomass and moisture content was done. A Hyundai excavator (23.5 ton) with a Pallari stump-head was used for the stump lifting and a Timberjack 1710 was used for the extraction of stumps. Time needed …
… cm). Mean plant depth was not correlated with wave exposure or epiphytic biomass suggesting that local sediment factors were more important in this lake. Furthermore, a comparison with 7 randomly located sites without Elatine showed the water content of the surface sediment was …
… grödeproduktionen och djurhållningen. Tidsserier med klimat, nederbörd och biomassa blir här viktiga metoder för uppskattning av Afrikas naturesurser. Nu finns omfattande organisation kring uppbyggande och användande av bl a nederbörds- och satellitbildsdata. Fjärranalysmetoder …
… was fed for 10 hours. The pain level was measured as feed intake in percent of biomass, since feed intake is a very good indicator of the well-being of the fish. Before vaccination the fish was sedated with benzocain, the routine sedative at vaccination. The vaccine used was …
