COMBUSTIBLE FUEL FEEDING SYSTEM AND COMBUSTIBLE FUEL FEEDING METHOD
PROBLEM TO BE SOLVED: To provide a combustible fuel feeding system and a combustible fuel feeding method capable of efficiently feeding a combustible fuel having high combustibility and a combustible fuel having low combustibility to a calcination furnace.SOLUTION: There is provided a combustible fuel feeding system 10 which comprises a calcination furnace 60. a rotary kiln 40, an air quenching cooler 80, a clinker raw material feeding part 70, a bleed duct 20, a first combustible fuel feeding inlet 21 and a second combustible fuel feeding inlet 22. The combustible fuel feeding inlet 21 is formed in the bleed duct 20. The second combustible fuel feeding inlet 22 is formed in the bleed duct 20 or the calcination furnace 60. A first calcination furnace arrival distance a between the first combustible fuel feeding inlet 21 and the calcination furnace 60 is longer than a second calcination furnace arrival distance b between the second combustible fuel feeding inlet 22 and the calcination furnace 60. The average value of the moisture content of a combustible fuel g1 fed from the first combustible fuel feeding inlet 21 is larger than the average value of the moisture content of a combustible fuel g2 fed from the second combustible fuel feeding inlet 22.SELECTED DRAWING: Figure 2
【課題】燃焼性の高い可燃性燃料と燃焼性の低い可燃性燃料とを効率よく仮焼炉に投入することができる可燃性燃料投入システム及び可燃性燃料投入方法を提供すること。【解決手段】可燃性燃料投入システム１０は、仮焼炉６０と、ロータリーキルン４０と、エアクエンチングクーラ８０と、クリンカ原料投入部７０と、抽気ダクト２０と、第１可燃性燃料投入口２１と、第２可燃性燃料投入口２２とを備える。第１可燃性燃料投入口２１は抽気ダクト２０に形成されている。第２可燃性燃料投入口２２は抽気ダクト２０又は仮焼炉６０に形成されている。第１可燃性燃料投入口２１と仮焼炉６０との間の第１仮焼炉到達距離ａは、第２可燃性燃料投入口２２と仮焼炉６０との間の第２仮焼炉到達距離ｂより長い。第１可燃性燃料投入口２１から投入される可燃性燃料ｇ１の含水分率の平均値は、第２可燃性燃料投入口２２から投入される可燃性燃料ｇ２の含水分率の平均値より大きい。【選択図】図２
