(JA) セメントクリンカーの製造方法
Abstract: front page image
(EN)The present invention provides a cement clinker manufacturing method capable of effectively suppressing the concentration of dioxins in the exhaust gas without significantly changing the process. The cement clinker manufacturing method comprises a step of producing a modified cement clinker raw material mixture by adding slaked lime having a terminal settling velocity from 0.5 to 10 cm/sec to a cement clinker raw material mixture, and a step of introducing the modified cement clinker raw material mixture to the pre-heater of a cement clinker production facility equipped with a pre-heater and a kiln.
(FR)La présente invention concerne un procédé de fabrication de scories de ciment capable de supprimer efficacement la concentration de dioxines dans le gaz d'échappement sans modifier significativement le procédé. Le procédé de fabrication de scories de ciment comprend une étape de fabrication d'un mélange de matières premières de scories de ciment modifié par ajout de chaux hydratée ayant une vitesse de sédimentation terminale de 0,5 à 10 cm/s à un mélange de matières premières de scories de ciment, et une étape d'introduction du mélange de matières premières de scories de ciment modifié dans le préchauffeur d'une unité de fabrication de scories de ciment équipée d'un préchauffeur et d'un four.
(JA) 本発明は大幅なプロセスの変更をせずに、排ガス中のダイオキシン類の濃度を効果的に抑制することのできるセメントクリンカーの製造方法を提供する。セメントクリンカー調合原料中に、終末沈降速度が0.5~10cm/secである消石灰を添加することで改質されたセメントクリンカー調合原料を作製する工程と、プレヒーター及びキルンを備えたセメントクリンカー製造設備のプレヒーターに当該改質されたセメントクリンカー調合原料を投入する工程を含むセメントクリンカー製造方法。
