- Sep 30, 2003I agree. How tight is your packing or rachik ring size? Too tight can cause flooding and too small a column diameter does the same thing. Does your boiler have power/temp adjustment or just on/off? If it does adjust then just ramp it up a bit at a time after its initial boil. Don't think I could do without a temp controller now I've used one.

Sounds like a very bad case of flooding the column. Try reducing the
heat input to your boiler. What diameter is your column? 1500 watts
should work fine on a 2 inch diameter column with scrubbers. I don't
know how the rachig rings will do.
