Abstract:
Provided is a cement kiln burner device that can freely form a desired combustion state according to the fuel used during an operation. The present invention relates to a cement kiln burner device including a plurality of flow channels partitioned by a plurality of concentric cylindrical members, the cement kiln burner device comprising: a solid powder fuel flow channel; an outer air flow channel group that includes a first air flow channel disposed adjacent to and inside the solid powder fuel flow channel and including a swirling means for airflow, and three or more second air flow channels concentrically arranged in the outermost shell outside the solid powder fuel flow channel and forming a straight flow means for airflow; and a flammable solid waste flow channel that is disposed inside the first air flow channel. The three or more second air flow channels constituting the outer air flow channel group are arranged radially close to each other within a range in which the airflows ejected from the respective second air flow channels can be joined to each other to constitute one airflow, and are configured to be able to control the flow rates of the airflows ejected from the respective second air flow channels independently of the second air flow channels.
