Abstract

Perfectionnement des fours, chaudières et autres appareils tubulaires de transfert de chaleur où ce transfert pour une part non négligeable par rayonnement. Il consiste essentiellement à mettre en rotation un ou plusieurs tubes de la zone de radiation et à installer des écrans protecteurs devant les tubes les plus chauds, au niveau où le flux thermique est le plus intense. L'invention peut être utilisée pour augmenter les taux de transfert moyens et donc pour réduire de manière importante les investissements.
