Does anybody understand how anti-foam works? Have been using it for a few months about 1 quart per barrel of sulfite.
I think the active ingredient is polyethylene glycol. Does it change surface tension or is it acting in some other way.
Before our condensate conductivity often ran over 1000 uS, at times it was the same as boiler water.
Now condensate runs 20-50 uS.
