Provided is a combustible waste blowing device and an operation method therefor that can suppress landing combustion of combustible waste, as well as an excessive change in the state of a flame generated in a cement kiln burner even when the use ratio of combustible waste varies. This combustible waste blowing device comprises a combustible waste flow path that is disposed inside an air flow path in the innermost shell, is arranged so as to be parallel with the axial direction of a cement kiln burner device, and allows the flow of combustible waste to pass therethrough. The combustible waste flow path has a slanted surface in the vicinity of a suction port, said slanted surface being slanted upward toward the suction port such that the flow-path width in the vertical direction becomes narrower with increasing proximity to the suction port.
