Measurement of the conductivity of boiler steam and condensate water
Thread Content
1. For the measurement of the conductivity of the condensate water generated by boiler steam, the temperature should be 160 degrees, with a range of 0–200 us/cm. A temperature and pressure reduction device is required; typically, the measurement is carried out at temperatures between 0–100 degrees. Can electrodes made of 316L stainless steel, equipped with PT1000 temperature compensation, be used? The required range can indeed be achieved! I need expert advice!
Question: What is the purpose of measuring the conductivity of the condensate water from this boiler?
It’s not clear; it might be the boiler’s condensate. By measuring the conductivity, one can determine whether it’s necessary to drain the water from the boiler
Monitoring the conductivity of condensate water is more reasonable than monitoring its hardness, as leaks in the condenser increase the salt content in the condensate. Even if the hardness level is within acceptable limits, other salts can still affect the parameters of steam and feedwater. Since conductivity reflects all conductive substances, monitoring the conductivity of condensate water provides a more sensitive indication. Using a conductivity meter for continuous monitoring of the conductivity of condensate water can overcome the delays associated with periodic testing, as well as the inability to detect changes in the quality of condensate water during the time between tests. Continuous monitoring prevents such issues and achieves the goal of ongoing surveillance.
