Abstract

Dans une chaudière disposée afin qu'un gaz de combustion généré par un brûleur (101) s'écoule depuis un foyer (102) par un surchauffeur (SH)(104) et un groupe de tuyaux de vapeur (105), une plaque de blindage aval (11A) capable de coulisser dans la direction verticale du surchauffeur (104) est prévue sur le côté d'écoulement glissant du gaz de combustion au-dessus du surchauffeur (104) afin de réguler le débit du gaz de combustion qui pénètre dans l'espace supérieur A du surchauffeur (104). Le débit d'un gaz de dérivation (12) est régulé par la plaque de blindage aval (11A) et le débit d'un gaz d'écoulement principal (13) est régulé, régulant ainsi la température de la vapeur du surchauffeur (104).
