CORROSION CONTROL METHOD FOR HEAT EXCHANGER AND CORROSION CONTROL STRUCTURE FOR HEAT EXCHANGER

摘要

A corrosion control method for a heat exchanger equipped with heat transfer pipes which exchange heat with a gas flowing in a flow path on the inside of heat transfer pipe securing members, wherein a configuration is adopted whereby the heat transfer pipes are equipped with cylindrical sleeves inserted or fitted around the outside of the heat transfer pipes, and the heat transfer pipes and/or the sleeves are moved relative to the heat transfer pipe securing members.
