Combined Cycle HRSG & Piping Lifecycle Management
This course will provide attendees a comprehensive understanding of Heat Recovery Steam Generator (HRSG) and High Energy Piping (HEP) in Combined Cycle power plants, and the elements necessary to manage that equipment throughout its lifecycle. Attendees will learn about design, operation, and maintenance with a particular focus on the potential damage mechanisms and how to avoid or mitigate them.
The course will cover the following topics:
1. HRSG and Piping: Introduction, Scope and Background
2. Materials of Construction
a. Carbon steels, low alloy steels, CSEFs, and stainless steels
b. Where are materials used and why
c. What are key concerns
d. Welds: heat affected zones and dissimilar metal welds
3. Damage / Degradation Mechanisms
a. Corrosion and Pitting
b. Cold-End Deposition and Gas Side Corrosion
c. Flow Accelerated Corrosion (FAC)
d. Corrosion Fatigue
e. Low Cycle Fatigue and Thermal Fatigue
f. Creep and Material Overheating
g. Oxidation and Exfoliation
4. Key Components (Code requirements, design considerations, common problems)
a. Feedwater heaters and economizers
b. Evaporators and Drums
c. Superheaters and Reheaters
d. Attemperators / Desuperheaters
e. Vents, Drains and Dampers
f. Flow controls, duct burners, SCRs, etc.
g. Structural steel, casings, liners
h. Piping systems (Feedwater, Main Steam, Cold Reheat, Hot Reheat, Bypasses and Auxiliaries such as transition cooling)
5. Water and Steam Chemistry
a. Fundamentals
b. Cycle chemistry options
c. Key considerations and problems
6. Operations and Maintenance
a. Operating Modes (Base Load, Cycling, Low-Load)
b. Impact of Cycling
c. Life Management Programs
7. Data Management
a. ii. Risk Ranking / Risk Based Inspection
b. iii. Inspection Technologies
c. iv. Lifetime Assessment
d. v. Online Monitoring
e. vi. Life Management Plans
8. Case Studies
a. FAC and Evaporator deposits (risk ranking, evaporator tube sample analysis)
b. Attemperator cracking (inspection, lifetime assessment, monitoring)
c. Steam drum cycling (lifetime assessment)
d. Tube-to-header cracking on a superheater (NDE, life assessment, lab)
e. Superheater Outlet Header branch cracking (NDE, Life assessment, Grade 91)
f. High energy piping life management plan (inventory, stress, NDE plan)
