DEVICE FOR PREVENTING ATTACHMENT OF DUST TO EXHAUST GAS FLOW CHANNEL INNER WALL FACE AND BRUSHING OFF ATTACHED DUST

摘要

PROBLEM TO BE SOLVED: To prevent the attachment of dust to an inner wall face of a gas flow channel such as an exhaust gas duct and a gas cooling tower in a combustion system, and to brush off the attached dust before growing.;SOLUTION: A plurality of blind-shaped members 28 are mounted along an inner wall face at an upper position of the gas cooling tower 6, and each blind-shaped member 28 is suspended down and supported from a driving device 36 through a suspension line-shaped member 35. The blind-shaped member 28 is moved up and down by the driving device 36, thus the dust in the exhaust gas 2 is prevented from attached to the inner wall face of the gas cooling tower 6, and the dust 14 attached to the inner wall face of the gas cooling tower 6 is brushed off when the blind-shaped member 28 is moved down. The dust 14 attached to the blind-shaped member 28 is also shaken off.;COPYRIGHT: (C)2006,JPO&NCIPI
