“…There are many recent reports describing the deposition of ZrC films by a variety of physical vapor deposition (PVD) or chemical vapor deposition (CVD) based techniques [5][6][7][8][9]. It appears that is rather difficult to obtain high quality ZrC films, because the same properties that make ZrC very attractive for applications, such as high melting point (T m = 3445 8C), low sputtering or evaporation rates, together with Zr high affinity for oxygen [5,7,10,11] are rendering the deposition of thin films difficult.…”

“…Pascale et al examined the integration of TPV and generator of Organic Rankine Cycle and were able to reduce the intensity of the input energy [10]. Cockeram and Hollenbeck used an emitter surface that was coated with substances of high emissivity which led to the development of efficient systems [11]. They showed that an alternative approach would be to use cells that have an energy band gap proportional to the spectrum of the emitter resulting in the enhanced efficiency of a TPV system.…”

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.

“…Gas turbine, solar energy and thermophotovoltaic radiator applications are also concerned with YSZ coatings [2,7,8]. In all these applications, it is very important to account for the radiative behaviour of the system.…”

“…Some studies on the radiative properties of YSZ thermal barrier coatings are found in the literature [2][3][4][5][6][7][8]11,12]. The measurements on plasma-sprayed thermal barrier coatings (PS-TBCs) [2] and on EB-PVD thermal barrier coatings (EB-PVD-TBCs) [3,4] show that the YSZ TBC is spectrally selective, and the emissivity decreases as the ceramic coating thickness increases.…”
