摘要： There are provided a cement kiln burner device capable of intensively bringing a combustible solid waste into a floating state within a cement kiln and easily causing ignition of the combustible solid waste in the floating state, and a method for operating the same. According to the present invention, there are provided: a powdered-solid-fuel flow channel including means for swirling a powdered-solid-fuel flow; a first air flow channel placed inside the powdered-solid-fuel flow channel to be adjacent to the powdered-solid-fuel flow channel, the first air flow channel including means for swirling an air flow; a second air flow channel placed in an outermost side outside the powdered-solid-fuel flow channel, the second air flow channel including 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 channel is divided in a circumferential direction into four or more opening portions adapted to form ports for injecting air flows, and is configured to control flow rates of the air flows ejected from the opening portions, independently for each opening portion.

摘要： There is provided a combustible waste injection device and a method for operating the same which can suppress a landing combustion of a combustible waste and suppress excessive change of a flame state from a cement kiln burner even if a rate of using the combustible waste fluctuates. The combustible waste injection device according to the present invention is provided with a combustible waste flow channel which is arranged in an inner side of the air flow channel in an innermost shell, is installed in parallel to an axial direction of the cement kiln burner device and is provided for flow feeding a combustible waste flow, and an assist air inflow port which can flow an assist air flow into the combustible waste flow channel toward an axis center of the combustible waste flow channel in the vicinity of an injection port of the combustible waste flow channel, and the assist air inflow port is arranged at a plurality of positions in relation to a circumferential direction.

摘要： A cement kiln burner includes a plurality of columnar or cylindrical flow channels. Outlets of the respective flow channels are disposed on substantially the same plane. A wind velocity adjusting member capable of changing a cross-sectional area at an outlet-side tip-end portion of the flow channel by moving along an axial direction of the flow channel in a state of being in contact with any one of an inner peripheral wall and an outer peripheral wall of the flow channel and not in contact with the other is provided inside at least one of the flow channels.

摘要： 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.

摘要： 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.
