HEAT RECOVERY STEAM GENERATORS (HRSG)

HEAT RECOVERY STEAM GENERATORS (HRSG)

HRSGs experience significant thermal transients, operate under wide range of loads, and experience high steam temperatures and pressures. Consequently, the HRSG is exposed to a significant range of damage mechanisms. Our staff have design, assessment, and operations experience that can tackle the full range of challenges, from poorly designed drains on attemperator systems through cycle chemistry and flow-accelerated corrosion audits to creep-fatigue and oxidation of creep strength-enhanced ferritic steels. Additionally, if a component failure occurs, Structural Integrity has extensive experience in Metallurgy and, when combined with our own Materials Science Center, can provide testing and perform failure root cause analysis to identify causative factors to prevent future or recurring failures.

HRSG CAPABILITIES AND SERVICES

SI can provide audits of HRSG design and operation to evaluate which damage mechanisms may be active, assess likely lifetime, and recommend inspection methods and inspection intervals

Operational and design reviews are performed to provide insight into cycle chemistry and concerns with the HRSG in the water-steam system (e.g. steam turbine or condenser)

SI expertly helps optimize your inspection strategy by reducing the inspection frequency on lower-risk components and focusing on needed inspections to maximize asset life

With the latest in tools and technologies, Structural Integrity’s trained and experienced NDE professionals perform inspections for HRSG tubing, piping, and headers

Our services address all aspects of CSEF design, procurement, fabrication, installation, operation, analysis, and inspection

SI’s experts can review attemperator design, operation, maintenance, and control logic to identify deficiencies, assess impact, and advise on mitigations from modified control logic to design upgrades. We also offer online attemperator monitoring software as part of our PlantTrack software

HRSG CAPABILITIES AND SERVICES
Boilers

Boilers

SI optimizes reliability through condition assessment and lifecycle management of your boiler components.Our comprehensive, integrated approach to boiler lifecycle management includes risk-ranking components and applying cycle chemistry reviews, inspections, fitness-for-service and metallurgical analysis to reduce forced outage rates and allow plants to operate with greater flexibility.

Our Boiler Services

Our boiler asset management program begins with an extensive pressure-part audit, resulting in an assignment of a health index to each component and reporting recommendations for future inspections, repairs, and replacements

Fitness-For-Service (FFS) evaluations offer predictions of crack growth and remaining life to help set inspection intervals and supply critical defect sizes to guide disposition of NDE results. FFS assessments explore the impact of changing operations (temperatures, ramp rates) providing insight into failure modes such as leak before break

Our experience with root causes combined with tube failure and condition assessment conducted in our Material Science Center, results in recommendations that prevent future failures

Our team of experienced engineers and NDE professionals use state-of-the-art ultrasonic and eddy current methods to detect and quantify damage in a range of boiler components

We are the industry leader in reviewing cycle chemistry to avoid tube failures due to mechanisms such as corrosion fatigue, under deposit corrosion, pitting attack, and stress corrosion cracking
