The HT BTES plant in Emmaboda: Report from the first three years of operation 2010-2013
2014 (English)Report (Other academic)
The Emmaboda HT-BTES was taken into operation 2010. Since then ~10 GWh has been stored, only a fraction has been extracted, and a storage temperature of 40-45 oC has been reached. The purpose of the BTES is to utilize waste heat from the industrial processes. Heat sources have been added annually and in 2015 the predicted heat injection (3.6 GWh/year) will be reached. Performed simulations are based on actual heat injection and extraction. The simulation model can reasonably well predict the future operation of the BTES. Initial problems with circulating the heat carrier at a slight vacuum pressure have been solved by using vacuum pumps to degas the fluid. The BTES has reduced the amount of bought district heating by approximately 4 GWh/year. To improve the system further, and reduce heat losses, it is suggested that a heat pump should be installed for heat extraction.
