<p>The method for charging a shaft furnace with bulk material of different defined size, comprises supplying the bulk materials in different positions related to horizontal cross-section of the interior of the shaft furnace to obtain a uniform distribution of the bulk material related to the cross section of interior of shaft furnace. The supplying of the bulk material is carried by a conveyor belt (11). The conveyor belt is moved from a resting position (A) to a final processing position (C) over a middle processing position (B). The method for charging a shaft furnace with bulk material of different defined size, comprises supplying the bulk materials in different positions related to horizontal cross-section of the interior of the shaft furnace to obtain a uniform distribution of the bulk material related to the cross section of interior of shaft furnace. The supplying of the bulk material is carried by a conveyor belt (11). The conveyor belt is moved from a resting position (A) to a final processing position (C) over a middle processing position (B). The conveyor belt is present in the resting position external of the horizontal cross-section of the shaft furnace. A part of the conveyor belt is located in the middle processing position within the horizontal cross-section of the interior of the shaft furnace. The conveyor belt does not intersect the vertical central axis of the shaft furnace. The conveyor belt is present in the final processing position within the horizontal cross-section of the shaft interior and does not intersect the vertical central axis of the shaft furnace. The conveyor belt is horizontally shifted. The supplying of the bulk materials is carried out at different positions during the conveyor belt is moved between the middle operating position and the final operating position. The relation such as N/2= P is fulfilled by the method, where N is a distance between the central axis of the shaft furnace and the position, in which the conveyor belt is crossed when moving from the resting position to the final processing position of the horizontal cross-section of the shaft furnace interior and P is a distance between the middle processing position and the final operating position. The shaft furnace contains a feed line (8) through which the bulk material is supplied into the shaft furnace via the conveyor belt. The conveyor belt is in operation during opening the feed line. The shaft furnace has a rectangular horizontal cross-section. An independent claim is included for a device for charging a shaft furnace.</p> |
