Abstract

See full text

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.
