Title
(EN) CONDUIT OF A CALCINER IN A CEMENT CLINKER PLANT
(FR) CONDUIT D'UN FOUR DE CALCINATION DANS UNE INSTALLATION DE SCORIES DE CIMENT
Abstract
(EN)
A conduit for a calciner (10) of a cement clinker plant, having an enclosed reaction space (20) being enclosed by a side wall defining an inlet (12) in and an outlet (13) of the enclosed reaction space (20), enabling a flow (3) of a fluid via the enclosed reaction space (20) along a trajectory (2) from the inlet (12) to the outlet (13) provides an improved fuel economy and an enhanced homogeneity of the fluid if the conduit has a first section (30) with at least one first surface portion (31) being inclined towards the trajectory (2) and a second surface portion (32) being inclined away from the trajectory (2).
(FR)
La présente invention concerne un conduit pour un four de calcination (10) d'une installation de scories de ciment présentant un espace de réaction fermé (20) étant entouré par une paroi latérale définissant une entrée (12) et une sortie (13) de l'espace de réaction fermé (20), ce qui permet un écoulement (3) d'un fluide par l'intermédiaire de l'espace de réaction fermé (20) le long d'une trajectoire (2) s'étendant de l'entrée (12) à la sortie (13), fournit une économie de carburant améliorée et une homogénéité améliorée du fluide si le conduit a une première section (30) ayant au moins une première partie de surface (31) inclinée vers la trajectoire (2) et une seconde partie de surface (32) inclinée à l'opposé de la trajectoire (2).
