… NOx, the emissions of hydrocarbon increases with 60-80 kg and the emissions of particles remains the same. The increased content of easy available nitrogen is about 40 tons, it can replace about 5 % of the nitrogen supplied as synthetic fertilizer. The contribution to the …
… the model is described and a first study of air quality considering PM10 (particles with a diameter less than 10 µm) in two Swedish municipalities, Vänersborg and Gnosjö, is introduced. According to the result, there are areas with poor air quality even in smaller Swedish …
… is preceded by a scrubber and both energy exchange and separation of unburnt particles have been studied. The facility studied is connected to a wood stove at 30 kW. The tests would show that the effect from the stove never reached above 16 kW. This might be a result of the low …
… related and that carefulness should be applied not to inhale powders, nano-particles or fumes from the material. The waste products may be either come in the form of breaking away parts or emissions. Emissions should then be handled in the same way as emissions are managed …

Intresset för biobränsleproducerad energi har ökat i takt med att kunderna blivit mer miljömedvetna. På grund av detta har efterfrågan på briketter ökat samtidigt som träindustrin har haft det svårt i en sviktande konjunktur. Därför har ett examensarbete utförts i samarbete med …
… is estimated at 25 kg of CO2, 553 g of NO2, 67.5 g of SO2 and 2.5 g of dust particles. The average spot price for electricity would, based upon empirical data for the past two years, see an increase of 54%.The results of the study clearly shows that the production cost of …
… already occurred. Furthermore, try also to comminute the material (reduce the particle size) at the plant and as close in time to combustion as possible.
<em>Modell för jämförelse av vägöverbyggnader med eller utan geotextiler och/eller geonät</em>
… subgrade by usinggeogrid soil reinforcement, which occurs when road material particles wedge inthe geogrid’s mesh. Geotextiles act partly as a barrier that prevents the finermaterial in the below ground from being mixed with coarser upper material andalso act as a load …
skakförsök baserade på två svenska långliggande kalk- och fosforgödslingsförsök
… 44% of human emissions of phosphorus to lakes and rivers. Leaching occurs of particle bound phosphorus and of dissolved phosphate. The amount of phosphate in the soil solution that may be leached is partly due to the prevailing pH in the soil solution. The purpose of this study …
… increase in methane concentration from about 65 % to about 97 %. In addition, particles and contaminants must be sepa-rated from the upgraded biogas. There are various methods for upgrading and this report compares six different methods with respect to environment and economy …
