There is provided a combustible waste injection device and a method for operating the same which can suppress a landing combustion of a combustible waste and suppress excessive change of a flame state from a cement kiln burner even if a rate of using the combustible waste fluctuates. A combustible waste injection device according to the present invention has a combustible waste flow channel which is arranged in an inner side of the air flow channel in an innermost shell, is installed in parallel to an axial direction of the cement kiln burner device and is provided for flow feeding a combustible waste flow, and the combustible waste flow channel has an inclined surface having a rising slope toward the injection port near the injection port in such a manner that a flow channel width in a vertical direction is narrowed toward the injection port.
