Energy Dissipation and Recovery in the Context of Silicon Production: Exergy Analysis and Thermoelectricity
Børset, Marit Takla (Doctoral thesis at NTNU;2015:315, Doctoral thesis, 2015)The metallurgical industry is power intensive and produces not only metals but also large amounts of excess heat. To increase the energy efficiency in this industry is thus of major interest, from both an environmental ... -
Exploring the potential for waste heat recovery during metal casting With thermoelectric generators: On-site experiments and mathematical modelling
Børset, Marit Takla; Wilhelmsen, Øivind; Kjelstrup, Signe; Burheim, Odne Stokke (Journal article; Peer reviewed, 2016)Thermoelectric power generators are scalable and simple systems for recovering waste-heat disposed by the industry. We combine on-site measurements and a mathematical model to study the potential for power generation with ... -
Harnessing thermoelectric power from transient heat sources: Waste heat recovery from silicon production
Savani, Isha; Waage, Magnus Heskestad; Børset, Marit Takla; Kjelstrup, Signe; Wilhelmsen, Øivind (Journal article; Peer reviewed, 2017)Thermoelectric generators (TEGs) are compact and robust devices for converting heat into electrical power. In this work, we investigate the response of a bismuth-telluride based TEG to the transient environment of a silicon ... -
Seebeck coefficients of cells with lithium carbonate and gas electrodes
Børset, Marit Takla; Kang, Xue; Burheim, Odne Stokke; Haarberg, Geir Martin; Xu, Q.; Kjelstrup, Signe (Journal article; Peer reviewed, 2015)The Seebeck coefficient is reported for thermoelectric cells with gas electrodes and a molten electrolyte of one salt, lithium carbonate, at an average temperature of 750 °C. We show that the coefficient, which is 0.88 mV ... -
Seebeck coefficients of cells with molten carbonates relevant for the metallurgical industry
Kang, X.; Børset, Marit Takla; Burheim, Odne Stokke; Haarberg, Geir Martin; Xu, Q.; Kjelstrup, Signe (Journal article; Peer reviewed, 2015)We report Seebeck coefficients of electrochemical cells with molten carbonate mixtures as electrolytes and carbon dioxide|oxygen electrodes. The system is relevant for use of waste heat and off-gases with concentration of ...
