Ammonia salts, sulfur and fouling pack the fins of a heat recovery steam generator, choking gas flow and driving up backpressure. Dry ice blasting is the accepted way to clean finned tube surfaces — no water wash, no grit, no secondary waste — restoring heat transfer during your planned outage.
Water washing an HRSG creates contaminated runoff and leaves moisture in the unit. Dry ice cleans the fins dry — no waste stream, no erosion, no waiting.
Dry ice blasting is a widely accepted practice for cleaning HRSG fin surfaces — effective on ammonia salts, sulfur deposits and corrosion products without harming the tubes.
Clearing fouling off the fins brings back heat transfer and gas flow, reducing backpressure on the turbine.
The CO₂ sublimates on contact — unlike water or grit washing there is no runoff to collect, treat or dispose of.
Dry ice removes deposits without eroding fin material or tube walls, protecting the asset you are cleaning.
Adjustable lances and nozzles reach between tube rows to clean deep in the bundle, not just the face.
We plan the work to fit your scheduled outage so cleaning doesn't extend downtime.
From the finned bundle to the transition duct — dry ice restores heat transfer surfaces without a drop of wash water.
Remove ammonia salts, sulfur and fouling from fin surfaces to restore heat transfer and gas flow.
Clean between tube rows with lances and adjustable nozzles — deep in the bundle, not just the face.
Clean catalyst and SCR faces as scoped, without water or media that could foul the element.
Remove buildup from inlet duct, transitions and dampers around the unit.
Detail economizer and superheater surfaces where deposits cut efficiency.
Clean shell-and-tube exchangers, coils and fin-fan surfaces across the plant. See heat exchanger & condenser cleaning for the dedicated service.
Water washing creates contaminated runoff you have to capture and treat, and leaves moisture behind. Dry ice cleans the fins with no water and no secondary waste, and the surfaces are dry immediately.
Using tube-lane lances and adjustable nozzles we clean between tube rows, not just the face — the extent depends on bundle geometry and access, which we assess up front.
No. Dry ice is non-abrasive; it lifts deposits through thermal and kinetic effect without eroding fin or tube material.
Yes — HRSG cleaning is planned around your scheduled outage so it fits the downtime you already have.
