Abstract

Provided is a corrosion control method for a heat exchanger including heat transfer pipes that perform heat exchange with gas flowing through a flow path located closer to an inner side of heat transfer pipe fixing members. A configuration including tubular sleeves fitted around or inserted into the heat transfer pipes is adopted, and at least one of the heat transfer pipes and the sleeves is moved with respect to the heat transfer pipe fixing members.
