PROBLEM TO BE SOLVED: To prevent coal particle from accumulating on the bottom plate of a CWM storage tank. ;SOLUTION: CWM which is jetted out from a jetting port 20 is prevented from accumulating by stirring coal particles 17 being accumulated on a bottom plate 19 of a CWM storage tank, and is removed. CWM which is jetted out from an auxiliary jetting port 22 is prevented from accumulating by stirring the coal particles 17 being accumulated on the bottom plate 19 under a jetting pipe 13, and is removed. Since a downcomer 12 and the jetting pipe 13 rotate with the center of the CWM storage tank as the pivotal center, the coal particles 17 being accumulated under the jetting pipe 13 are removed extending to the total peripheral area of the CWM storage tank, and the coal particles 17 being accumulated under the jetting pipe 13 do not obstruct the rotation of the jetting pipe 13, and do not apply an excessive force to a running mechanism 18 and the downcomer 12, and a device can be safely operated without being damaged.;COPYRIGHT: (C)1997,JPO
