Abstract

L'invention concerne un système de suivi de chaleur électrique d'un réservoir de stockage de cendres volantes (1) pour l'incinération de déchets domestiques, lequel système comprend le réservoir de stockage de cendres volantes (1) et un dispositif de chauffage disposé sur une paroi externe du réservoir. Une partie supérieure du réservoir de stockage de cendres volantes (1) a une structure cylindrique (2), et une partie inférieure de celui-ci a une structure en entonnoir (3). Le dispositif de chauffage est constitué par des blocs chauffants (4) disposés à proximité, attachés et fixés sur la paroi externe du réservoir et ayant une fonction de chauffage indépendante, les blocs chauffants (4) ayant chacun une face chauffante et la face chauffante étant étroitement attachée à la paroi externe du réservoir. La paroi externe du réservoir de stockage de cendres volantes (1) comporte de plus un élément de mesure de température (5), et une boîte de dérivation de câble électrique et une armoire de commande de température sont disposées sur la paroi externe du réservoir de stockage de cendres volantes (1). L'armoire de commande de température commande les blocs chauffants (4) à l'aide de la boîte de dérivation de câble électrique, résolvant le problème de l'état antérieur de la technique selon lequel une chemise chauffante doit être remplacée dans son ensemble.
