| abstract | PROBLEM TO BE SOLVED: To provide a performance recovery method and a performance recovery device for recovering the performance of a heat exchanger by removing low heat conductive materials such as acidic ammonium sulfate deposited on the heat exchanger while continuing the operation of the heat exchanger. SOLUTION: When ammonium sulfate or acidic ammonium sulfate precipitates and adheres to the inside of a heat exchanger 1, the supply of water to a heat transfer tube of a selected gas passage cell in the heat exchanger is stopped, and the selected gas passage A step of discharging water in the heat transfer pipe of the cell, a step of heating the heat transfer pipe from which water has been discharged with hot gas, and decomposing these salts by setting the tube wall temperature to a temperature higher than the decomposition temperature such as ammonium sulfate, Alternatively, the step of cleaning the heat transfer tube after the decomposition of the acidic ammonium sulfate and the step of restarting the supply of water to the heat transfer tube are sequentially performed on the gas passage cell provided in the heat exchanger 1.
