In case of thermal power plant, the flue gas from FGD (Fuel Gas Desulfurization) process goes through the cooler, then the gas is desulfurized at the absorption tower. During this process the gas temperature gets cooler while it is going through the absorption tower and leads to white smog in the stack. GGH Reheater, object of this study, is a device that reheats clean gas by using the absorbed heat from cooler in order to reduce the white smog. In general, the problems of the conventional GGH Reheater are, firstly, the attachments on the tube get bigger by time goes, and this condition reduces heat-transfer performance by interfering the gas flow inside tubes. And secondly, managing cost is very high since the device cannot be repaired, and the whole device needs to be discarded once the closure rate of the tube reaches 10%. And lastly, as well as the tube, the suspension (exterior frame), which supports tube bundles, once the connecting parts gets corroded or fractured, the damaged part cannot be repaired or maintained.
