Improving HRSG Reliability & Long-term Ageing Management – Best Practices in Protecting your HRSG Investment

CMI, CMI Energy, HRSG Reliability, Aftermarket Services, HRSG Maintenance, Free Webinar, Webcast Experts



Combined Cycle Gas Turbine (CCGT) power plants operating under rapidly changing market conditions have to minimize costs and maintain a high reliability in order to be competitive. Typically, CCGT plants are designed to operate under specific parameters and duty cycles. Variations in capacity factors and duty cycles can place increased thermal stress and fatigue on the Heat Recovery Steam Generator (HRSG) pressure parts and other sensitive components impacting reliability and performance. This can lead to unexpected outages resulting in high costs of repair & replacement, reduced plant availability, and loss in net revenue. Therefore, adopting adequate maintenance practices, timely inspections, and condition assessments are imperative for avoiding unscheduled outages and protecting the life of your HRSG investment.

Brussels: 11 AM | Dubai: 1 PM | New Delhi: 2:30 PM | Bangkok: 4 PM

In this informative webinar, Habib Grini, Aftermarket Services & Construction Manager from CMI, will review key elements comprising successful inspections, remaining life analysis, redesign for upgrading and fabrication of HRSG components.

Specific topics to be addressed will include:

  • Major deficiencies in current HRSG design

  • Inspection protocols and best practices

  • Root cause analysis prior to HRSG repair

  • HRSG perfomance recovery

  • How to recover and revamp boilers to adequate mechanical and operations behaviour

  • Boilers and diverter dampers - Examples of recent analysis, modelling, upgrades and proven construction solutions

  • Remaining life time assessment

  • Boiler stress analysis - hardware and software to optimize boiler performance and minimize consequences of cycling HRSG operation

  • Root cause determination to identify solutions to pressure part leakage issues

  • Impact of GT upgrade, how to adapt old HRSG with adequate redesign and assessments for expected new performances

In addition, several case studies for aftermarket solutions will be discussed, including:

  • Damages & solutions behind GT 26 at Dock Sud Argentina

  • HP Economizer Flow distribution analysis and repetitive tube leakage problems and long term solutions at Carthage Power Tunisia

  • Dewa Burners ducting-casing and expansion joint upgrades on Station G

  • HP Evaporator full re-tubing and recovering of nominal performance on a 20-year boiler operations at Liberty TNB Pakistan

Attendees can ask additional questions which will be covered during the Q&A session at the end of the webinar.

This webinar can help you make informed decisions about measures used to extend HRSG lifetimes and improve CCGT plant availability.
