Part I divides the TPV system into its five major components—combustor, emitter, radiant transfer system, photocell, and power conditioner. Using the best data available to the authors from experimental studies, plus theoretical analysis where useful, the probable upper bound of efficiency for each part of a practical TPV device is estimated. A probable overall TPV efficiency of 13% is obtained for a combustion flame temperature of 2000 °C and a fibrous ytterbium oxide emitter temperature of 2000 K. If a flame temperature of 2300 °C and emitter temperature of 2000 °C are possible, this efficiency may approach 22%. Experimental plus analytical studies of the combustor, emitter and radiant transfer system are recommended that should determine what the maximum TPV system efficiency is likely to be. These studies would also give the design data needed for building a practical TPV device. Part II is an analytical model of the radiant transfer system for a fibrous or solid emitter plus thermal and photocell shi... |
