Floating balls on boiler feed water? Ever heard of that?

I was reading a book from Spirax Sarco and it recommended using floating balls in the boiler feed unit to limit the oxygen during long off times like you would see in a brewery. The balls act like a blanket system. It said it will limit the O2 scavenger needed in system. Never heard that before and wanted to see if you ever did.
Thanks

    I've heard of it, @RayWohlfarth , but never seen it. No good reason why it wouldn't help, at least a bit. Also cut down on evaporation from the feed tank, if it's hot.

    They do that in the reservoirs in the LA area. Not super pertinent, but interesting nonetheless.

    Could not the floating balls potentially block the boiler feed tank vent or overflow?

    @jsavage I heard they work great to lower the odors
    @EBEBRATT-Ed Good point never thought about that

    Interesting video. The math suggests they paid $32,000,000 for the balls though. Seems like a very pricey solution.

    It requires thinking and forethought but venting can be eliminated. What's the good of expelling air and then letting it back in?
