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 first 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.SELECTED DRAWING: Figure 2 |
