Provided is a burner apparatus for a cement kiln, which strongly forms a floating state of combustible solid waste in the cement kiln, and easily ignites the combustible solid waste in a floating state; provided also is a method for operating the burner apparatus. The burner apparatus of the present invention comprises: a solid powder fuel flow path provided with a solid powder fuel flow swirlingmeans; a first air flow path that is disposed inside the solid powder fuel flow path and adjacent thereto and provided with an air flow swirling means; a second air flow path that is disposed on the outermost shell outside the solid powder fuel flow path and provided with an air flow straight-forwarding means; and a combustible solid waste flow path disposed inside the first air flow path. In thesecond air flow path, an opening constituting an air flow outlet is divided into four or more openings in the circumferential direction, and the flow rate of the air flow ejected from the openings canbe controlled independentl
