Oil removal from Low Pressure Steam Boilers?
(OP)
Upon new installation of cast iron sectional steam boilers, low pressure, how is it best to remove oil from the boiler?
Surface blow-down appears to be working, just extremely slow.
An old wash-down recipe was the use of soda-ash combined with kerosene. Anyone doing that type of work these days? Or is there a new compound that can help wash it out as a non-adhering sludge?

We have used Halliburton to clean our boilers on several occasions. We have used others but none are are no longer in business,

Here is the old Oakite Co. that supplied a lot chemicals to us or the contractor to do process equipment cleaning. I don't know their position now with on-site cleaning.

To bring in an outfit like Haliburton to clean a little residential/commercial cast iron section steam boiler would probably cost as much as the installation.

In your case I would get with the manufacturer and see what they recommend. If this doesn't bear fruit I would contact a local chemical company or their representative to discuss your problem.
If you have to use the material as stated in the OP I would make sure as a minimum that I incorporated a rinse aid. Sodium salts aren't as bad as they would be on other metals, so if you can rinse out the cleaning solution it should be no problem.
Calgon did make some rinse aids for alkaline cleaning solutions or if the volume is small enough you could use a dishwasher rinse aid.
Can you come back on high thick the oil is? If it is very thick I would circulate the hot cleaning solution before I adding the Kerosene

ahardware store 5lbs per 100 GL will do,
after flush and add defomeing compound
or flush twice, add your boiler chemicals and check pH and alkalis.
