… and facilities warm. Steam is exclusively used in the heat pretreatment. Thermal energy consumption was as following: Keeping the biogas digester warm consumed close to 20 % of the total heating demand, corresponding to 40,8 kWh/ton.Heat pretreatment accounted for 62 % of the …
… energy efficiency. From the energy aspect, the facade is afflicted with poor thermal insulation which is a big problem. To address this problem adding insulation is a good alternative to reduce overall energy consumption of a building. The windows on these buildings are also a …
… seven fields; nature, noise, color, wayfinding, safe environment, daylight and thermal comfort which has been assessed to be applicable on housing. In order to obtain a comprehensive overview of the different fields, four different subjects were chosen to investigate further …
Ett examensarbete om akustik- och brandkrav samt en jämförelse av energi- och fuktaspekter
… some assumptions have been made in cases when data are lacking. U-values and thermal bridges were calculated in the simulation software Comsol. The hand calculated U-values are consistent with the data calculated in Comsol. The results show that the concrete wall has a higher …
En studie av ureasönderfall under kvävgasatmosfär
… heavy trucks. In my experimental setup with TGA-DSC-FTIR (a combination of two thermal analysis methods and a method for gas phase detection), an FTIR method for urea in the gas phase was developed for the qualitative and quantitative determination of urea and its decomposition …
… as a guide for the Stockholm Arena to reduce theconsumption of purchased thermal energy, with the aim of producing its own energy.This is reported from a technical perspective, focusing at the design of a propersystem. Heat energy is today planned to be brought from district …
… a preference for south-facing slopes, where they could take advantage of thermal updrafts for flying. The results show that a landscape mosaic of open areas and older pine forest could be favourable for the juvenile eagles and that south-facing slopes should be excluded from …
… in factories needed to be monitored. Since Salmonella pathogenesis is complex, thermal process and pelleting may not be enough meth-ods to eliminate the Salmonella completely from feed. Recontamination may be occurring during cooling or transportation. The future perspective of …
… materials. There an object was located in the ground had importance for if thermal alteration occurred and how great the alteration was. The biggest risk for damage was on material in the peat and where was some alteration on material just beneath the surface of the sand …
… such as biocides. If the problems of Legionella growths are not repeated, the thermal disinfection is a good alternative. If the problem however is repeated and a general increase in temperature in the system does not stop the bacteria growths, then biocides should be used.
