BURNER APPARATUS FOR CEMENT KILN AND METHOD FOR OPERATING SAME

摘要

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 swirling means; a first air flow path that is disposed outside 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 outside the first air flow path and adjacent thereto and provided with an air flow straight-forwarding means; a third air flow path that is disposed inside the solid power fuel flow path and adjacent thereto and provided with an air flow swirling means; and a combustible solid waste flow path disposed inside the third air flow path. The second air flow path has openings that form air flow outlets, and closed parts that are blocked so that the air flow cannot flow therethrough, and the openings and the closed parts are arranged alternately in the circumferential direction.
