“…As a result, the porous quartz glass is used both as an optical filter and a heat storage medium in the super-adiabatic combustion TPV system, which is an advantage over conventional combustion-driven TPV systems. (17)(18)(19) In our previous work, (20) the parameters of the porous quartz media and the operative conditions were optimized by numerical analysis, so that a theoretical conversion efficiency from combustion heat into spectrally-controlled radiation of 56% was achieved using a broad band emitter. The total efficiency of the TPV system is therefore expected to be 17% when the conversion efficiency of the TPV cell is 30%.…”

A prototype thermophotovoltaic (TPV) generation system based on super-adiabatic combustion with reciprocating flow in porous media was developed experimentally. Stacked porous quartz glass plates in the system were used as an optical filter and for heat storage. The distributions of temperature and spectral radiation indicated that both energy recirculation and spectral control were realized with the quartz glass plates. In addition, electric power was obtained by introducing the spectral controlled radiation into GaSb cells. The measured output power was in close agreement with that estimated using a parallel ray-tracing model. Application of a one-dimensional configuration to this system is expected to result in a total fuel to electricity conversion efficiency that would reach 10%. Consequently, a spherical super-adiabatic combustion TPV system is proposed as an idealized one-dimensional system to achieve this.

“…The radiation on the cell is segregated into two parts, one part which can be converted into electrical power and the other part includes the absorbed and reflected radiation. The reflected radiation is depicted via line number (5) and the absorbed radiation heats up the cell itself. Consequently, the cell temperature rises and considerably exceeds the ambient temperature which leads to heat loss and is denoted by line number (6).…”

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.

Investigation of the entropy generation and efficiency of a solar thermophotovoltaic system

Based on the second law of thermodynamics, a theoretical model is established for efficiency analysis and optimization of a solar thermophotovoltaic (STPV) system. The entropy generation in the photo-electricity conversion process is numerically calculated and analyzed for the component modules involved in the whole system assembly. The effects of the emitter temperature, concentration ratio, energy bandgap, cell temperature and the transmissivity of the filter on the entropy and the efficiency are investigated. Meanwhile, the conversion efficiencies of the modules are discussed. The following results are obtained: at first the entropy generation of the system reduces but then increases with the rise of the emitter temperature. When the concentration ratio improves, the entropy generation of the system falls. The increase of the bandgap value and chemical potential of the cell also causes the reduction of the entropy generation. Along with the increase of the cell temperature, the entropy generation increases and the conversion efficiency of the STPV system decreases.
