… (about 20 samples) and wet chemical analysis (about 20 samples + 2 fly-ash samples) was then performed on the samples. A sample from each boiler was sent for BETanalysis. The results from the analysis above were compared to earlier studies conducted on bio-fuel plants in order …
… between the growing site of bio fuel, the chemical composition of bio fuel ash and the deposit growth in a bio fuel fired boiler.” The purpose of this degree thesis was to avoid melted deposit growth in the bio fuel fired boiler at ENA Kraft in Enköping. Potassium and sodium are …
odlingsfaktorernas inverkan på havrens bränsleegenskaper
… a fuel. When compared with wood, cereals contain higher amounts of Cl, S and ash. The Cl and S content makes the gases from cereal combustion more corrosive than gases from wood combustion. The goal of this master thesis was to find out the variation of Cl, S and ash content for …
… for the individual deliveries and there is a risk for systematic mistakes. Ash content part varied with 5 % between the deliveries. Since the method for measuring ash content is statistical uncertain this parameter value for the parameter should be estimated by visuel …
Metoder för slurrytillverkning
… Norrköping. The report shows methods to manufacture slurry consisting of fly ash and water. The slurry shall be pumped into several former oil storage rock shelters that E.ON has put into operation for the specific purpose. The ash mixture also develops hydrogen gas in contact …
Askåterföringen på fastmark syftar till att återställa den långsiktiga näringsbalansen och motverka markförsurningen. Den är ett led i ett kretsloppstänkande där allt som tas ifrån marken också ska återföras.Ett ökat behov av skogsbiobränslen leder till att grenar och toppar …
effects of peeling and pearling on chemical composition, taste and colour
… of the grains have been used on common and durum wheat. The dietary fibre and ash content, as well as germination was analysed in untreated, peeled, pearled and polished grains. The decrease in dietary fibre and ash was higher in grains that had been pearled compared to those …
en sammanställning av spridningsbar aska i södra Sverige
I takt med ökande intresse för uttag av grot så ökar också intresset för återföring av aska tillbaka till skogen. I rapporten utreds hur mycket återföringsbar aska som produceras av förbränningsanläggningar. Arbetet begränsas genom att endast förbränningsanläggningar med större …
… provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too …
Eyjafjallajökull is made of textile, ash and pigment. Itis a publication which tells the story of the ash cloudthat stopped Europe. The primary goal of the projectwas to use textile as material and screen printing asmethod to present the story of Eyjafjallajökull. Theaim was to …
Teoretisk analys och praktisk försök
… 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 heat radiating combustion chamber …
… different haylage diets was calculated by using the amount of acid-insoluble ash in feed and faeces as an internal marker. The apparent DMd was different in the three haylage diets. June haylage had the highest apparent DMd and August the lowest. There was no difference in …
en utvärdering av effektivitet och avfallshantering ur ett miljöperspektiv
Filtermaterial av 75 % torv och 25 % kolaska har använts under 2 respektive 4 år för rening av avloppsvatten från två biltvättar. Jämförelse med Kristianstads kommuns riktvärden för avloppsvatten från fordonstvättar visar att filtren fungerat. För avfallsklassning krävs kunskap …
… characteristics that differ from normal biomass, such as high amount of ash and extractives. High ash content leads to secondary reactions in the reactor, which leads to lower yields of bio-oil. Because of this the knots are not an optimum raw material for fast pyrolysis. At the …
… reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass. The aim with this study was to decide whether wood ashes that been used for biogas upgrading with …
