A New Practical On-line Equipment to Monitor and Evaluate Fouling and Corrosion of Heat Exchanger

To adopt protective measure and guarantee safe and economic operation for heat exchanger, it´s necessary to accurate monitor and evaluate fouling and corrosion of heat exchanger. Point at the imperfection of present method to monitor fouling and corrosion of heat exchanger, A new practical online equipment was developed based on the soft-measure technology for fouling with easily measured parameters and the mental corrosion rate monitoring technology with the weak polarization method, and introduces mainly the measuring principle, the structure, the performance and the application of the monitoring equipment based on the above principle
