The second workshop conducted at the 2018 meeting of the Australasian Boiler and HRSG Users Group covered the types of corrosion found under insulation (CUI)—galvanic, chloride, acidic, and alkaline-induced—attributed to moisture buildup on the external surfaces of insulated equipment (piping and vessels). If untreated, CUI leads to corrosion and forced or extended outages. Common temperature

The user-only compressor session in 2018 didn’t include any new topics, at least while the editors were in the room. At most 6B meetings, discussions include filter experience (HEPA in particular in recent years), online and offline washing, corrosives and particulates in the air impacting compressor cleanliness (and how to remove them), inlet bleed heat,
With much of the time at Frame 6 meetings devoted to user presentations and deep discussion, there remains limited time for vendor presentations. Each year, the steering committee chooses two third-party vendor presentations in tune with what owner/operators are experiencing in the field. The topics selected for the 2018 meeting dealt with combustion hardware and

Discussion on the turbine section always is robust at Frame 6 Users Group meetings, likely because there are many “senior” machines in the fleet—those with well over 100k operating hours. Current thinking of the OEM and a few others is that an end-of-life inspection should be done at about 100,000 hours and that the rotor
