HRSG Cleaning
Restore heat recovery efficiency with precision dry ice blasting — during planned outages.
About This Service
What Is HRSG Cleaning?
Heat Recovery Steam Generators accumulate fouling on tube bundles, finned tubes, headers, and ductwork that progressively degrades thermal efficiency. Even a thin layer of deposit can reduce heat transfer by 10–15%, directly impacting power output and fuel consumption.
Dry ice blasting removes fouling from HRSG tube bundles and internal surfaces without the water infiltration risk of hydroblasting or the debris concerns of air lancing. CO₂ sublimates on contact — no secondary waste, no drying time, no risk to tube coatings.
Our HRSG cleaning crews are experienced in planned outage coordination, confined space work, and the strict documentation requirements of power utility clients.

Why Dry Ice
The Advantages
Safer, cleaner, and faster than any traditional industrial cleaning method.
Restore Thermal Efficiency
Remove fouling that degrades heat transfer — restoring rated HRSG output and reducing fuel costs.
No Water Infiltration
Eliminates the corrosion and drying-time risk associated with hydroblasting tube bundles.
Confined Space Capable
Compact equipment and flexible hose allow access to tight HRSG internals and elevated tube sections.
Outage Window Optimized
Faster than hydroblasting with no drying time. Maximize what gets done in a planned outage window.
Utility-Grade Documentation
Before/after thermal imaging and photo documentation for maintenance and regulatory records.
Tube-Safe Process
Non-abrasive — won't damage fin tubes, coatings, or base metal. Safe for older HRSG units.

The Process
How It Works
From first call to clean equipment — a clear, efficient process every time.
Outage Coordination
We align with your outage schedule, safety protocols, and confined space entry procedures in advance.
Access & Equipment Setup
Blasting units and hose runs staged outside the HRSG. Equipment positioned for full tube bundle coverage.
Tube Bundle Blasting
Finned tubes and internal surfaces cleaned section by section. Zero water, zero abrasive media introduced.
Thermal Verification & Closeout
Documentation package completed. HRSG cleared for recommission at end of outage window.
