Experiments were conducted in a test heat exchanger system to evaluate 10 nonchemical scale and corrosion control devices. These devices may perform either by electrostatic, magnetic, electronic, or catalytic mechanisms. Chemical tests also compared results with nonchemical systems to insure the test conditions were not so severe that scale prevention was impossible. Water from a single deep well known to cause calcium carbonate scale when heated was used in all tests. The test heat exchanger was a two-tube shell and tube with steam applied to the shell side. Water flow was either in series or parallel through the two tubes, depending on the desired test conditions. No device tested significantly reduced the amount of scale formed, compared to the controls. Proprietary chemicals containing phosphorus reduced scale formation almost completely.
