I need an expert’s help: what are the conductivity control parameters for boiler water at 4.2 MPa?
Thread Content
The pressure in our factory’s boilers is 4.2 MPA, and the conductivity has always been measured according to
Neither GB/T1576-2018 nor GB12145-2016 specifies this 150 microsi value; please check your operating procedures
The standards specified in the regulations are higher, so they aren’t very useful as a reference; I just want to know if raising the conductivity to 60-80 will have a significant impact
You’re referring to the electrical conductivity of the furnace water, right? In GBT 12145-2016, this parameter isn’t specified either for furnaces operating at 3.8–5.8 Mpa; it’s not specified even for those operating at higher pressures
The relevant specifications and standards do not include such a high value for conductivity; it is recommended to contact the furnace manufacturer or the original design institute for confirmation.
There is a typo here; it should be the boiler manufacturer.
The steam parameters are fine; I haven’t paid much attention to them lately
It’s likely there’s no major problem, after reading this post. We tested the conductivity of the water in our boiler, and it was also over 60. I inspected one unit last week and found no impact from water quality.
