  • Recurring 𝐭𝐮𝐛𝐞-𝐭𝐨-𝐡𝐞𝐚𝐝𝐞𝐫 𝐥𝐞𝐚𝐤𝐬 were driving unplanned outages and reducing steam production — forcing the plant to plug multiple tubes just to stay online. At the same time, 𝐝𝐞𝐠𝐫𝐚𝐝𝐞𝐝 𝐫𝐨𝐨𝐟 𝐢𝐧𝐬𝐮𝐥𝐚𝐭𝐢𝐨𝐧 created unsafe access conditions and limited maintenance visibility. 𝐍𝐨𝐨𝐭𝐞𝐫 𝐄𝐫𝐢𝐤𝐬𝐞𝐧 𝐝𝐞𝐥𝐢𝐯𝐞𝐫𝐞𝐝 𝐚 𝐟𝐮𝐥𝐥 𝐚𝐟𝐭𝐞𝐫𝐦𝐚𝐫𝐤𝐞𝐭 𝐬𝐨𝐥𝐮𝐭𝐢𝐨𝐧 designed to address both performance and accessibility: • Replacement coil bundles and retubing to 𝐫𝐞𝐬𝐭𝐨𝐫𝐞 𝐞𝐯𝐚𝐩𝐨𝐫𝐚𝐭𝐨𝐫 𝐜𝐚𝐩𝐚𝐜𝐢𝐭𝐲 • New roof panels to 𝐢𝐦𝐩𝐫𝐨𝐯𝐞 𝐬𝐚𝐟𝐞𝐭𝐲 𝐚𝐧𝐝 𝐚𝐜𝐜𝐞𝐬𝐬 • Targeted repairs based on 𝐚𝐬-𝐟𝐨𝐮𝐧𝐝 𝐜𝐨𝐧𝐝𝐢𝐭𝐢𝐨𝐧𝐬 𝐝𝐮𝐫𝐢𝐧𝐠 𝐭𝐡𝐞 𝐨𝐮𝐭𝐚𝐠𝐞 • Field Technical Advisor (FTA) support to 𝐞𝐧𝐬𝐮𝐫𝐞 𝐩𝐫𝐨𝐩𝐞𝐫 𝐞𝐱𝐞𝐜𝐮𝐭𝐢𝐨𝐧 The result: ✔️ Restored steam production and 𝐨𝐩𝐞𝐫𝐚𝐭𝐢𝐨𝐧𝐚𝐥 𝐟𝐥𝐞𝐱𝐢𝐛𝐢𝐥𝐢𝐭𝐲 ✔️ Reduced risk of 𝐮𝐧𝐩𝐥𝐚𝐧𝐧𝐞𝐝 𝐨𝐮𝐭𝐚𝐠𝐞𝐬 ✔️ Improved 𝐬𝐚𝐟𝐞𝐭𝐲 𝐚𝐧𝐝 𝐦𝐚𝐢𝐧𝐭𝐞𝐧𝐚𝐧𝐜𝐞 𝐚𝐜𝐜𝐞𝐬𝐬 ✔️ Extended 𝐨𝐯𝐞𝐫𝐚𝐥𝐥 𝐚𝐬𝐬𝐞𝐭 𝐥𝐢𝐟𝐞 📄 Swipe through the document to see how 𝐎𝐄𝐌 𝐚𝐟𝐭𝐞𝐫𝐦𝐚𝐫𝐤𝐞𝐭 𝐬𝐮𝐩𝐩𝐨𝐫𝐭 helps solve complex reliability challenges while preparing units for long-term performance. 📩 Contact our Aftermarket team: 𝐚𝐟𝐭𝐞𝐫𝐦𝐚𝐫𝐤𝐞𝐭@𝐧𝐞.𝐜𝐨𝐦 #NooterEriksen #HRSG #AftermarketSolutions #CaseStudy #OEMSupport #PowerGeneration #Reliability #EngineeringExcellence

  • 𝐀𝐟𝐭𝐞𝐫𝐦𝐚𝐫𝐤𝐞𝐭 𝐬𝐮𝐩𝐩𝐨𝐫𝐭 𝐢𝐬𝐧’𝐭 𝐣𝐮𝐬𝐭 𝐩𝐚𝐫𝐭𝐬 — 𝐢𝐭’𝐬 𝐮𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 𝐭𝐡𝐞 𝐟𝐮𝐥𝐥 𝐬𝐲𝐬𝐭𝐞𝐦. ⚙️ From HRSG internals to external piping, drain systems, and performance limitations — everything is connected. Our team works across the entire system to: • Identify root causes • Improve access and maintainability • Support long-term performance, not just short-term fixes Because solving one issue without understanding the system often leads to another.

  • 𝐃𝐫𝐚𝐢𝐧 𝐬𝐲𝐬𝐭𝐞𝐦 𝐢𝐬𝐬𝐮𝐞𝐬 𝐝𝐨𝐧’𝐭 𝐚𝐥𝐰𝐚𝐲𝐬 𝐬𝐡𝐨𝐰 𝐮𝐩 — 𝐮𝐧𝐭𝐢𝐥 𝐭𝐡𝐞𝐲 𝐛𝐞𝐜𝐨𝐦𝐞 𝐟𝐚𝐢𝐥𝐮𝐫𝐞𝐬. ⚠️ Hidden corrosion, trapped water, and flow bypass can quietly impact HRSG reliability over time. Many early HRSG designs introduced complex preheater and economizer drain systems that created ongoing challenges: 💧 Flow bypass driving localized tube failures 🛑 Bellows clogging and trapping moisture against drain lines ⚠️ Limited valve access complicating operation and maintenance 𝐖𝐞’𝐯𝐞 𝐬𝐞𝐞𝐧 𝐢𝐭 — 𝐚𝐧𝐝 𝐰𝐞’𝐯𝐞 𝐫𝐞𝐝𝐞𝐬𝐢𝐠𝐧𝐞𝐝 𝐢𝐭. Nooter Eriksen’s inverted bellow retrofit simplifies and strengthens the system: • 𝐅𝐞𝐰𝐞𝐫 𝐩𝐞𝐧𝐞𝐭𝐫𝐚𝐭𝐢𝐨𝐧𝐬 𝐚𝐧𝐝 𝐜𝐨𝐦𝐩𝐨𝐧𝐞𝐧𝐭𝐬— consolidated drain lines reduce bellows, valves, and leak points • 𝐈𝐦𝐩𝐫𝐨𝐯𝐞𝐝 𝐯𝐚𝐥𝐯𝐞 𝐩𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞 — metal-seated ball valves enable faster operation and more reliable shutoff • 𝐌𝐨𝐢𝐬𝐭𝐮𝐫𝐞-𝐫𝐞𝐬𝐢𝐬𝐭𝐚𝐧𝐭 𝐝𝐞𝐬𝐢𝐠𝐧 — inverted bellows help prevent trapped water and external corrosion • 𝐎𝐩𝐞𝐫𝐚𝐭𝐨𝐫-𝐟𝐨𝐜𝐮𝐬𝐞𝐝 𝐚𝐜𝐜𝐞𝐬𝐬 — centralized manifolds improve usability and maintenance The result: a more reliable, maintainable drain system built for today’s operating demands. ⚙️ 📩 Contact our Aftermarket team to learn how we can support your next outage: 𝐚𝐟𝐭𝐞𝐫𝐦𝐚𝐫𝐤𝐞𝐭@𝐧𝐞.𝐜𝐨𝐦 #NooterEriksen #HRSG #AftermarketSolutions #PowerGeneration #DrainSystem #OEMUpgrades #EngineeringExcellence

  • Backpressure isn’t just a number — it’s a signal. ⚙️ As HRSG tube bundles foul over time, exhaust backpressure increases — 𝐢𝐦𝐩𝐚𝐜𝐭𝐢𝐧𝐠 𝐜𝐨𝐦𝐛𝐮𝐬𝐭𝐢𝐨𝐧 𝐭𝐮𝐫𝐛𝐢𝐧𝐞 𝐞𝐟𝐟𝐢𝐜𝐢𝐞𝐧𝐜𝐲, 𝐡𝐞𝐚𝐭 𝐫𝐚𝐭𝐞, 𝐚𝐧𝐝 𝐨𝐯𝐞𝐫𝐚𝐥𝐥 𝐩𝐥𝐚𝐧𝐭 𝐩𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞. Left unaddressed, rising backpressure can lead to 𝐥𝐨𝐚𝐝 𝐥𝐢𝐦𝐢𝐭𝐚𝐭𝐢𝐨𝐧𝐬, 𝐫𝐞𝐝𝐮𝐜𝐞𝐝 𝐬𝐭𝐞𝐚𝐦 𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧, 𝐚𝐧𝐝 𝐢𝐧𝐜𝐫𝐞𝐚𝐬𝐞𝐝 𝐨𝐩𝐞𝐫𝐚𝐭𝐢𝐧𝐠 𝐜𝐨𝐬𝐭𝐬. 𝐓𝐡𝐚𝐭’𝐬 𝐰𝐡𝐞𝐫𝐞 𝐎𝐄𝐌 𝐬𝐮𝐩𝐩𝐨𝐫𝐭 𝐦𝐚𝐤𝐞𝐬 𝐭𝐡𝐞 𝐝𝐢𝐟𝐟𝐞𝐫𝐞𝐧𝐜𝐞.
