Abstract

Abstract:

Coolants corrode the metals in the circulation system and decrease the service life of energy tower significantly. To ensure the long life service of the equipments in energy tower, the corrosion compatibility between the materials in the circulation system of energy tower and the coolants should be confirmed. Herein, the corrosion behavior of H65 copper alloy, 3003 aluminium alloy and 20# low carbon steel in six typical commercial coolants was studied. The alliances between H65 copper alloy and YH6830 coolant, 3003 aluminium alloy and BL3500 coolant, 20# low carbon steel and HG3500 or YH6830 coolants are found to be optimal for corrosion control. This is significant for prolonging the service life of energy tower equipment.

Key words: energy tower, coolant, corrosion
