Problems with pH meters in wet flue gas desulfurization
Thread Content
May I ask everyone, for pH meters used in wet flue gas desulfurization, which manufacturer is better? We’re using ABB’s, and some people say it’s not very useful; while others don’t report any issues? Useful and good, please give some recommendations
Most of those I’ve seen are from E+H, and they’re quite good
1# ivysmile If it’s the plant owner, it depends on which manufacturer’s thermal control equipment is used throughout the plant; it’s best to use the same brand as that used elsewhere in the plant, to facilitate maintenance and other tasks. If it’s a bidder, it depends on the requirements in the tender documents. Recommend whatever the owner likes, Bey.
Both Honeywell and ABB are good options; the key is the installation method and location
The pH meters in the absorption tower are generally installed on the pipeline from the absorption tower to the swirl station, where they suffer significant wear and tear. For the convenience of maintenance and replacement, we use online plug-and-play ball valves. As mentioned by *a1974163*, the E+H models are said to be good, but we have not used them nor seen any power plants using them. Anyway, thank you all!
Under such operating conditions, specially designed electrodes and installation methods must be used. If it’s a regular product purchased through bidding, where a low-price bid wins the deal, it’s only natural that it won’t work well. Yokogawa’s PH meters for special applications cost at least 30,000 RMB per unit, and they come equipped with an automatic cleaning function ； The cost of DKK might be even higher.
I want to use it too; who can recommend some good manufacturers?
E+H: It hasn’t been used yet; it broke already during installation
