Abstract: A cement kiln burner device includes a powdered-solid-fuel flow channel, a first air flow channel placed inside the powdered-solid-fuel flow channel to be adjacent to the powdered-solid-fuel flow channel, having means for swirling an air flow, an outer air flow-channel group placed concentrically in an outermost side outside the powdered-solid-fuel flow channel, having three or more second air flow channels adapted to form means for straightly forwarding an air flow, and a combustible-solid-waste flow channel placed inside the first air flow channel. The second air flow channels are placed proximally to each other in a radial direction within a range where air flows ejected from the respective second air flow channels are merged to form a single air flow, and are configured to control flow rates of the air flow ejected from the respective second air flow channels, independently for each second air flow channel.

The second air flow channel includes an opening portion forming a port for injecting an air flow, and a closed portion covered for preventing an air flow from passing therethrough. The opening portion and the closed portion are alternately arranged in a circumferential direction.
