Poppy and the Steam Forum and Power Forum

Welcome to the steam and power forum, a bulletin board dedicated to questions and answers to Steam Plants and Power Generation Plants for steam boilers, turbine generator and heating problems. Dedicated to power plants, power generation, supercritical, and heating plants as well as steam boilers, steam turbine generators, gas turbines or combustion turbines, hrsg, steam heating, pressure vessels, steam line, including ASME questions and more.

Cationic conductivity

Tuesday, September 18, 2018   By: BOUZEBRADZ [1076] 1 Stars
I consider a high cationic conductivity of low pressure steam if it exceeds the value 0.2 micro S / CM. current value is 0.5 micro S / CM. what are the factors that make increase cationic conductivity..the values of cationic conductivity of MP AND HP are in standards.
thanks.

I would consider the limit of cation conductivity of feedwater to be 0.5 mS/cm and that is micros. If you are already in your combined cycle LP section then I think you are doing great, for the more metal ionic molecules that are added to treat the boiler water the more we boost the conductivity.

Specific conductivity of boiler water ions is in the range 1.7 to 2.4 approx.
The exception is Hydrogen ion and OH ion which are about 5
Thus you can say TDS is about half the conductivity if you can get OH ions out it. This is why you neutralise boiler waterwater to do a TDS
Doing a cationic conductity does the oposite as it exchanges any cation and replaces them with hydrogen ions. This has the effect of converting things like ammonia hydroxide to water eg NH4OH becomes HOH
The benefit in measuring steam is that the intended volatile contaminates are removed and the carryover solids are made to have a much higher conductivity.

A conductivity of 0.5 mS/cm2 is around 0.2 ppm of solids.
I am not amazed at how high it is but how low it is.

If you have seen it lower it means you have a higher drum level now allowing more carryover or a higher TDS allowing more foaming.

PS I should have added that if the cation resin is exhausted the conductivity will rise because you will be measuring volatiles.

High Sulfite Residual
By: Ross. [390]

First, I want to say that large amounts of Sodium Sulfite NaSO3 becomes a contaminate because it will produce foaming and other problems, but foaming is the primary problem.

Your 500-psi Water Tube Boiler is seems to have reasonable level of residual Sodium Sulfite NaSO3 remaining in the boiler water. Nice pH too.

Your 300-psi Waste Heat Recovery Boiler has twice what I would expect for Sodium Sulfite NaSO3 at ranging 80-ppm to 100-ppm. pH is good so you are getting a good yield.
