Abstract:
A cement kiln burner device includes a powdered-solid-fuel flow channel having means for swirling a powdered-solid-fuel flow; a first air flow channel placed outside the powdered-solid-fuel flow channel having means for swirling an air flow; a second air flow channel placed outside the first air flow channel having means for straightly forwarding an air flow; a third air flow channel placed inside the powdered-solid-fuel flow channel having means for swirling an air flow; and a combustible-solid-waste flow channel placed inside the third 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.
