Pure distilling reflux problems

[susie]

We have had this still for years. suddenly it is boiling in the tube, sounds like a train, and vapour is running out the top.

Things we have tried:
Tested the wash it is at lower than 1000
Repacked the column
checked the hole with a needle

Sounds like puking.
Try some butter, table spoon worth in the boiler

Reduce power supply, I had the same problem. If you don’t have a voltage controller you can use a 20 metre extension lead to lose a bit of power.
Another thing that works is running a desk fan directly on the boiler.

Have a look at your condenser. Make sure it’s not blocked.

Test the wash make sure its finished. Have found fg 1.010 or lower dont puke.

Do all the suggestions above and next run fill the boiler with less wash
