The user’s original high-sulfur area uses other brands of zirconia probes, and the service life is generally 3 months, and a new probe needs to be replaced in 3 months, and the use cost is extremely high.After on-site inspection by our company’s engineers, it was found that after the sulfur dioxide (SO2) in the pipeline flue gas was partially converted into sulfur trioxide (SO3), it formed sulfuric acid (H2SO4) with the moisture in the flue gas and condensed on the front end of the probe, resulting in zirconia. The probe is damaged by corrosion.
After replacing our company’s Nernst zirconia probe, because the Nernst zirconia probe can be purged directly without shutting down, it is equipped with an automatic purge box, and the oxygen analyzer is set to automatically purge the probe regularly, so that the sulfuric acid solution is formed as soon as it is formed. Purging and cleaning, the service life of the probe is more than one year. The user was very satisfied and purchased 2 additional sets.
