Hamon Deltak, Inc. has provided aftermarket services worldwide on over 185 projects for the last 25 years. Applications served: HRSGs, FCCU, Process Boilers, and CO/NOx Emissions Control Equipment
A Cogeneration facility calline in Hamon Deltak, Inc. (HDI) to perform a complete HRSG inspection during a scheduled outage. One of the issues that HDI found in the inspection was repeated economizer tube leaks, causing outages every other month. A full inspection was provided with immediate action items, plans for the next few outages, and items to keep tabs on.
During an outage the following year, HDI was asked to provide an improved economizer design, and replaced the upper return-bend economizer bundle with a multiple panel design that is fully ventable, and called for the support system and piping to be retrofit.
HDI provided engineering, fabrication, logistics, a site support system, and internal HRSG components. HDI also supplied a lifting and turning flame for handling the panels and provided a rigging procedure to maneuver the panels into their final positions. There hasn't been a tube leak since the retrofit.
