Boiler & HRSG Offline Inspections

The offline (or cold) inspection is an essential O&M activity at any thermal power or process plant. For steam generating equipment, whether it's a small industrial package boiler or a large utility-scale supercritical coal boiler, this is especially critical since only during a shutdown can the condition of all internal components be assessed in detail.
