CEMENT RAW MATERIAL FIRING DEVICE AND MANUFACTURING METHOD OF CEMENT CLINKER
To provide a cement raw material firing device allowing stable operation by suppressing "coming off" of calcined raw material.SOLUTION: A cement raw material firing device comprises a cement kiln 20, a calcination furnace 12 and a rising duct 14 connecting a kiln tail 22 of the cement kiln 20 to the calcination furnace 12. The rising duct 14 of the cement raw material firing device has, on an inner wall surface 14A, a projected throttle part 50 throttling an exhaust gas passage from the cement kiln 20. In a vertical directional section view passing a center line CL1 of the rising duct 14 and a rotation axis CL2 of a body part 26 of the cement kiln, an angle between a downward surface 51 of the throttle part 50 and the inner wall surface 14A is less than 90°.SELECTED DRAWING: Figure 2
【課題】仮焼原料の「抜け落ち」を抑制し安定的に運転をすることが可能なセメント原料焼成装置を提供すること。【解決手段】セメント原料焼成装置は、セメントキルン２０と、仮焼炉１２と、セメントキルン２０の窯尻２２と仮焼炉１２とを接続するライジングダクト１４と、を備える。セメント原料焼成装置のライジングダクト１４は内壁面１４Ａにセメントキルン２０からの排ガスの流路を絞る突起状の絞り部５０を備え、ライジングダクト１４の中心線ＣＬ１及びセメントキルンの本体部２６の回転軸ＣＬ２を通る鉛直方向断面で見たときに、絞り部５０の下向き面５１と内壁面１４Ａとのなす角度が９０°未満である。【選択図】図２
