description The invention relates to a cleaning method for inner tube scab dissolved by a fused salt heat exchanging segment. The method is characterized by comprising the following cleaning processes: clearly discharging inner tube material dissolved by the fused salt heat exchanging segment, continuously heating the fused salt heat exchanging segment, and damaging scab by interactional stress of tube and scab according to different heated expansion coefficients of the two to remove scab by self stripping of scab. The method of the invention effectively reduces the temperature of the outlet of a fused salt furnace of a device, prolongs cleaning period, lowers maintenance cost, effectively reduces system differential pressure, reduces high-pressure operation time of the device in the cleaning period, and is easy to implement, promote and apply industrially.
