PROBLEM TO BE SOLVED: To effectively prevent the contamination of a heat exchanger tube with deposit.;SOLUTION: In this method for preventing the contamination of the inner wall of the heat exchanger tube for passing a high-temperature waste gas with adhesion of an adhesive component contained in the waste gas, a high-pressure noncombustible fluid is intermittently injected into the tube from the discharge port side of the heat exchanger tube 141 by a high-pressure injection nozzle 25, and an air flow flowing back in the heat exchanger tube 141 is formed by the attracting force of the injected noncombustible fluid to blow off the deposit adhered to the tube inner wall.;COPYRIGHT: (C)2004,JPO
