Oil in feedwater

[blacklabs]

Assume a small amount of turbine oil found its way into a HP boiler. It may have entered the condensate system via the exhaust steam from a steam turbine to a surface condenser.How might this problem present itself if it made it to the HP drum ? Would foaming or priming be a possible result? Appreciate any and all input
Thanks

Yes, foaming would probably ocurr in the steam drum. You need to flush this oil out of your feedwater system.

Do you have to take the boiler down to flush it or do you just have to keep blowing it down until oil has been removed?Is there treatment that can be added quickly to prevent fouling of the tubes?

I believe that damage has been already been done while you were posting. Aside from the aforementioned foaming another big problem is the generation of CO2 that can give you fits in the condensate system.

Could you come back with the physical parameters of your boiler.

Water tube D type 220,000 # per hour gas fired.Not yet fired but wishing to prevent any problems.What test is most reliable to predict/prevent oil from entering feedwater?
