Summary:PROBLEM TO BE SOLVED: To air-purge cell holes of a stationary honeycomb heat storage body to remove dust, scale or the like in the cell holes, without causing increase of pressure loss or requiring arrangement of mechanical drive mechanisms in an air feed and exhaust flow passage.SOLUTION: A cleaning device of a honeycomb heat storage body (1) includes: a high pressure gas feed pipe (3) connected to a high pressure feed source (2); an ejection tube (5) connected to the high pressure gas feed pipe through a rotary joint (4); and a bearing (6) rotatably supporting the ejection tube. The rotary joint, the bearing and the ejection tube are arranged inside the air feed and exhaust flow passage (P) of a combustion system. The ejection tube includes: jetting apertures (7) for cleaning which blow an opened end face (Ha) of the heat storage body with jets of high pressure gas; and jetting apertures (8) for driving which blow jets for driving substantially parallel to the opened end face. The ejection tube is rotated by thrust forces acting on the ejection tube as reaction of the jets for driving.
