| Abstract: | The on line monitoring method was studied of the foul thermal resistance and corrosion rate in cooling water systems,an on line monitoring unit of the foul thermal resistance and corrosion rate in cooling water systems was developed that could simulate the cooling water flow and the condition of heat transfer,eliminate the self corrosion electric displacement and the solution IR drop,and the newly developed corresponding software realized the computerized automatic control for the whole measurement and data processing.The test result shows that the unit could truly reflect the scale and corrosion of heat exchangers. |
