HRSG Cleaning and Heat Recovery Steam Generator Services
Specialized dry ice blasting for HRSG units — finned tube bundles, SCR and CO catalyst beds, ammonia injection grids, duct burners, and inlet houses. Restore backpressure and heat rate without water or chemicals.
Schedule an AssessmentWhy Dry Ice Blasting
Combined-cycle plants lose efficiency as iron oxide, ammonia bisulfate, and combustion residue build up on finned tubes and catalyst faces. Traditional washes introduce water, chemistry, and long drying time.
Our crews mobilize for planned and forced outages with full containment, vacuum recovery, and trained HRSG technicians. The result: lower backpressure, recovered MW, and a dry, ready-to-fire unit when you're done.

Frequently Asked Questions
What is HRSG dry ice cleaning?+
HRSG (Heat Recovery Steam Generator) dry ice cleaning uses solid CO2 pellets accelerated by compressed air to remove iron oxide, ammonia salts, and combustion residue from finned tubes and catalyst surfaces without water, chemicals, or abrasive media.
Will dry ice blasting damage HRSG fins or catalyst beds?+
No. Dry ice is non-abrasive (Mohs hardness ~2) and sublimates on contact. When operated by trained technicians at correct pressures, it cleans aluminized fins, SCR, and CO catalysts without bending fins or eroding washcoat.
How much pressure recovery can we expect after HRSG cleaning?+
Most plants see backpressure reductions of 1–3 inches of water column and measurable heat-rate improvements after a full HRSG cleaning, depending on baseline fouling.
Can you work during an outage?+
Yes. We mobilize 24/7 for planned outages and forced outages nationwide. Most HRSG cleaning scopes are completed in 2–5 days depending on access and unit size.
Do you need water, drains, or containment?+
No water and no chemical drainage. We bring our own air, ice, vacuum recovery, and containment. The only waste stream is the loosened fouling itself.
