This invention concerns a nozzle for blowing secondary air into a combustion chamber having a rectangular-section box (6) consisting of four walls opposite one another two by two called the first walls (6A) and second walls (6B) and capable of being turned by a control device on an axis known as axis of rotation (7) traversing the said first walls (6A), the box being open on two opposite sides (6C, 6D), the one being the air inlet side (6D) and the other being the outlet side (6C) for this air for the combustion chamber. An assembly (12) with louvres perpendicular to the second walls (6B) is located in the box (6), each louvre (12A, 12B) capable of being turned by an actuating system on respectively an axis (13) perpendicular to the axis of rotation and cutting across it.
La présente invention concerne une busette de soufflage d'air secondaire dans un foyer de combustion comportant un caisson (6) de section rectangulaire constitué de quatre parois en vis à vis deux à deux dites premières parois (6A) et secondes parois (6B) et pouvant être tourné au moyen d'un organe de commande selon un axe dit axe de rotation (7) traversant lesdites premières parois (6A), le caisson étant ouvert sur deux faces opposées (6C, 6D), l'une étant la face d'entrée (6D) de l'air et l'autre la face de sortie (6C) de cet air dans le foyer. Une structure (12) de volets perpendiculaires aux secondes parois (6B) est disposée dans le caisson (6), chacun des volets (12A, 12B) pouvant être tourné grâce à un agencement d'actionnement selon respectivement un axe (13) perpendiculaire à l'axe de rotation et coupant celui-ci.
