Overview and Status of Thermophotovoltaic Systems

Abstract

In the last decade thermophotovoltaic (TPV) generator has gained an increasing attention as cogeneration system for the distributed generation sector. Nevertheless, these systems are not fully developed and studied: several aspects need to be further investigated and completely understood.\ud The aim of this study is to give a complete overview and the status of the art of thermophotovoltaic generation considering both the research developments and the experiences field. More in details, in this study, the characteristics of a TPV generator are analyzed with a particular attention to the physical relationships which govern the behavior of its main components. Moreover, the current technologies regarding the combustor, the emitter, the optical filter and the photovoltaic cells are investigated by taking into account both the role of each component and also their integration in the whole system. Finally, a critical review of the realized prototypes is presented and discussed

EAF Heat Recovery from Incident Radiation on Water‐Cooled Panels Using a Thermophotovoltaic System: A Conceptual Study

“…Maximum required power density for implementation to the EAF is predicted to be 70 . Although the power density is high, according to the literature, such TPVs are available. Figure b shows the electrical energy generated by the TPV.…”

Engineering design of direct contact counter current moving bed heat exchangers

“…Examples of solid cooling include coke dry quenching (direct gas contact) of the incandescent coke after coke ovens and prior to use in the blast furnace to raise steam, electricity or preheat wet coking coal (Bisio and Rubatto, 2000;Johansson and Söderström, 2011), production of hot water using heat exchange from cooling beds in steel production (Johansson and Söderström, 2011), cooling of cast slabs after hot ingot rolling to generate steam using radiant heat pipes (Horio et al, 1982), calcined sinter coolers using air as coolant, with heat recovery in a waste heat boiler or for feed preheat (Leong et al, 2009), air cooling of clinkers in the cement industry using grate coolers (Madlool et al, 2011) with potential to generate electricity via an organic Rankine cycle (Legmann, 2002), and multistage fluidised bed direct preheating of alumina calciner feed air by cooling of the hot calcine (Klett et al, 2010). Heat could also be recovered, in the form of electricity, from the walls of reactors, furnaces and hot transfer lines by utilising thermophotovoltaic devices (Ferrari et al, 2014) or thermoelectric devices (Zhao and Tan, 2014). This paper will focus on heat exchange between solid particles and gas in a moving bed arrangement.…”

A Metamaterial‐Plasmonic Scheme Based on a Random Metallic Network for Controlling Thermal Emission

“…High efficiency thermal photovoltaic (TPV) devices rely on shaping the emission spectrum of the employed absorber‐emitter, to match the spectral response of a photovoltaic (PV) detector . This can be most efficiently achieved with photonic crystals and metamaterials .…”
