ABSTRACT:
A self-sampling corrosion monitor is structurally adapted to be connected to the blowdown system or other piping systems external to a steam generator. The monitor includes a pump for providing positive solvent flow through the monitor, and a regenerative heat exchanger using recovered heat at the outlet. Magnetite is also added to a sludge cup within the corrosion monitor vessel to simulate real time measurement of short-lived corrosion conditions in the steam generator. In addition, the available corrosion monitoring equipment is modified to provide automatic microprocessor-controlled range selection. Still further, data acquisition, storage, and display techniques are modified.
