HRSG experience, issues typically global in nature

So you switch hemispheres in both directions, west to east then north to south, and you discover that the pesky HRSG operational issues and concerns you are familiar with are much the same everywhere. The 2018 Australasian Boiler and HRSG Users Group (ABHUG) Conference and Workshops, held last November, confirmed this view. The organization’s 11th […]

Don’t forget to inspect for corrosion under insulation

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 […]
