Abstract: In this study, a theoretical and experimental analysis are presented on thecompleteinterface problem between a solar concentration system and a high temperaturethermochemicalprocess in a rotary kiln. Radiative, conductive and convective heat transferbetween a freeboardof burden solid, the interior surfaces of a rotary kiln and the exterior mediumof a kiln areanalysed. The kiln operates in a cascade state and the hypothesis of well mixing isconsidered.The radiation flux density distribution in the receiver kiln, the solar and infraredbands radiationexchange and the useful heat transfer are all considered in the analysis. Theparameters such astemperature distribution in the kiln, as well as thermal efficiency aredeterminated in function formass flow rate of granular solids, the inclination angle and rotationalvelocity of the kiln and forincoming concentrated solar radiation.
