Abstract

Une chaudière à surchauffe comprend une chaudière principale disposée afin que les gaz de combustion générés par la combustion d'un brûleur s'écoulent depuis un foyer (102) par un surchauffeur et un groupe de tuyaux d'évaporation ; un foyer de surchauffe (108) muni d'un brûleur de surchauffe (107) sur le côté d'écoulement glissant du groupe de tuyaux d'évaporation ; et un surchauffeur (109) sur le côté supérieur du foyer de surchauffe (108), une partie d'alimentation en air de combustion (12) destinée à fournir une partie de l'air de combustion comme air de combustion (11b) étant prévue à un emplacement opposé au brûleur de surchauffe (107) dans le foyer de surchauffe (108). Le mélange du gaz de combustion (107a) et de l'air de combustion (11b) est accéléré par une contre-collision de ceux-ci afin de provoquer une variation de la configuration d'écoulement du gaz de combustion et, ainsi, un déséquilibre de température du gaz de combustion (107a) à réduire à la sortie du foyer de surchauffe (108).
