A big issue is the condensate purity.  Check the conductivity on a regular basis.  Check the silica levels in the boiler water, and boiler feed water.  silica carryover to the turbine will put it out of commission.  Condensate carryover is a big issue for a lot of different applications, including food processing and animal feeds where steam is used to inject into feed pellets for cooking and extraction.  In these application and in power plants steam and condensate purity is determined upstream and with proper condensate treatment.  So who thought up the idea of condensate filtration in the first place?  it shouldn't hurt anything, but the problem is not the filters: the problem is upstream.  Why?  Your job is not sales of new products or filters: your job is solving the problem.
