Combined use of an electronic antifouling technology and brush punching for scale removal in a water-cooled plain tube

摘要

The objective of the present study was to investigate the benefit of the combined use of an electronic antifouling (EAF) technology and brush punching for scale removal in a shell-and-tube heat exchanger. Two fouling experiments were conducted with new plain tubes: one without an EAF treatment and the other with it. Scale inside the two tubes was produced in a recirculation-flow system with an artificially hardened water of 7.5 mol/m~3.
