Dimensionering av pelletspanna : Ångkartläggning och dimensionering av en ny pelletspanna hos Fresenius Kabi i Kungsängen

Sammanfattning: The current boilers at the Brunna plant were installed in 1979 using oil and solvents to produce steam for the production and heating of the plant. To reduce the carbon dioxide emissions in compliance with Fresenius Kabi strategy a new biofuel boiler is about to be installed. Since the steam demand has been reduced during the years and it’s expensive to install a new boiler this study has been performed to calculate the actual steam demand for the plant at different scenarios. A smaller boiler requires a lower investment, achieves higher efficency and contributes to reduced carbon dioxide emissions. This report is intended to supply the management with information so that a decision regarding investments and employees can be made. The result is presented as different possible scenarios that are of great importance when deciding which boiler effect that is needed. Destillation, heating and the production have a major impact and must be considered when installing a new boiler. The results show that a boiler should be between 2-4 MW net effect depending on which scenario that is most likely to occur.
