Energieffektivisering av Forsbacka oljesystem
Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
Skellefteå Kraft owns and operates the district heating network in the town of Lycksele. For this they have two sites, Skogsbacka CHP plant and Forsbacka heating plant. Forsbacka is the smaller plant with four boilers, two wood chip boilers and two that are oil-fired. The Forsbacka plant is mainly used during summer and at peak loads. For storage and supply of oil to the oil-fired boilers there are two 100 m3 cisterns. The oil system is old and built for heavy oil, which means that the oil has to be kept at minimum temperature of 35°C
The aim of this report is to examine possible measures to make the storage and handling of the oil more energy and cost efficient.
The results show that it would be a good idea to change to light oil and thus be able to lower the oil temperature to at least 20°C. This would halve the cost for keeping the oil warm, whereas an increased insulation of the cisterns would not be cost efficient. Another recommended measure for energy saving would be to install frequency converter for speed regulation of the oil pumps, which would reduce the energy use to halve.
