a b s t r a c tThe potential for using Thermophotovoltaic (TPV) generators as an alternative for recovering energy losses in steel production industry is assessed. A mathematical model for the assessment of the performance of TPV application in the iron and steel industry has been developed. In order to support the mathematical model, a sample TPV apparatus in laboratory scale based on an IR emitter has been designed and assembled. The key modeling parameters of TPV generator include: the open circuit voltage, the short circuit current density and fill factor of the TPV cell. These parameters have been considered in the model as functions of several variables such as: the emitter (hot steel slab) temperature, the cell temperature, the distance between the cells and emitter, the spectral response and the cell energy gap. The External Quantum Efficiency (EQE) as an important indicator of the cell's spectral response is included in the model. Moreover, the variation of the emitter temperature has been considered. Several tests have been carried out for different values of the cell-emitter gap. It has been found that when the GaSb cells are used for energy recovery, a minimum temperature of 873°C is required. The upper limit of the emitter temperature is usually determined in steel production process associated with hot rolling process which has a temperature around 1250°C. Finally, the total efficiency of the system was obtained to 4.12%, when GaSb cell with temperature of 27°C and slab emitters with temperature of 1257°C are used. The results of the simulation of the model in a casting process at the Mobarakeh Steel Complex have shown a potential of energy recovery of 26.987 MJ per year.

The theoretical potential for converting excess heat from the iron and steel sectors in Turkey into electricity by the use of thermophotovoltaic (TPV) systems is investigated and analyzed. The TPV usage in this industry is numerically investigated because this sector is in the leading position in terms of energy consumption in industrial sectors. Using the iron and steel industry waste heat energy data, it is shown that the energy conversion efficiencies of the TPV systems with the photovoltaic (PV) cell modules of In0.2Ga0.8As0.18Sb0.82 and GaSb are 7.31 % and 2.04 %, respectively. When using TPV systems in the Turkish iron and steel sectors for waste heat energy potential, it is calculated that 29.88 MJ per year can be generated with GaSb cells, and 1.076 PJ per year can be generated with In0.2Ga0.8As0.18Sb0.82 cells. Based on the results obtained from the numerical model in this study, some specific advice for the applicability and the development of the high efficiency TPV conversion systems is proposed.

“…The efficiency of the system is increased if the spectrum of the heat radiation and the PV diode cell characteristics are matched. [63][64][65][66] The most common TPV cell materials are gallium antimonide, silicon, and indium gallium arsenide [67]. Construction and analysis of systems where TPV is combined with ORC [68] or TEG [69] have been conducted and reported.…”

Industrial excess heat is a large untapped resource, for which there is potential for external use, which would create benefits for industry and society. Use of excess heat can provide a way to reduce the use of primary energy and to contribute to global CO 2 mitigation. The aim of this paper is to present different measures for the recovery and utilization of industrial excess heat and to investigate how the development of the future energy market can affect which heat utilization measure would contribute the most to global CO 2 emissions mitigation. Excess heat recovery is put into a context by applying some of the excess heat recovery measures to the untapped excess heat potential in Gävleborg County in Sweden. Two different cases for excess heat recovery are studied: heat delivery to a district heating system and heat-driven electricity generation. To investigate the impact of excess heat recovery on global CO 2 emissions, six consistent future energy market scenarios were used. Approximately 0.8 TWh/year of industrial excess heat in Gävleborg County is not used today. The results show that with the proposed recovery measures approximately 91 GWh/year of district heating, or 25 GWh/year of electricity, could be supplied from this heat. Electricity generation would result in reduced global CO 2 emissions in all of the analyzed scenarios, while heat delivery to a DH system based on combined heat and power production from biomass would result in increased global CO 2 emissions when the CO 2 emission charge is low.
