HRSG Tubes & Fin Fan Coolers External Cleaning

HRSGTubes

Heat Recovery Steam Generators (HRSGs) and Air-Cooled Heat Exchangers (Fin Fan Coolers) gradually accumulate contaminants such as dust, soot, carbon, oily deposits, corrosion products, and environmental fouling. These deposits reduce heat transfer efficiency, increase exhaust back-pressure, elevate operating temperatures, and reduce overall plant efficiency.

 

Our cleaning services restore optimal performance, reduce downtime, and extend equipment life.

Dry Ice Blasting (CO₂ Cleaning)

A non-abrasive, non-water cleaning method ideal for delicate fins, HRSG external tubes, and equipment where water is not allowed.

 

Advantages

 

No moisture — safe for electrical & insulation areas

No chemical residue

Safe for aluminum fins and delicate surfaces

Removes dust, soot, light carbon, grease

No equipment cool-down required

Environment-friendly

Applications

HRSG tube external surface

Fin Fan Cooler bundles

Gas turbine & HRSG exhaust cleaning

High-Pressure Air Blowing

Used where deposit load is dry, loose, or moderate.

Specifications

Air pressure: 6–10 bar

Special nozzles to safely penetrate fin gaps

Continuous cleaning without shutdown

Advantages

Quick and economical

No water, no chemicals

Suitable for desert-area fouling (dust, sand)

Fin fan coolers exposed to dust & sand

HRSG convection section fouling

Alkaline Chemical / Detergent Washing

For heavy oil fouling, sticky contamination, industrial pollutants, bugs, and hardened deposits.

 

Chemicals Used

Mild alkaline detergents

Non-corrosive fin cleaning agents

Biodegradable surfactants

Procedure

Apply chemical foam or spray

Soak for penetration

Rinse with controlled-pressure water or air

Drain and restore to service

Removes oil, grease, bugs, sticky contaminants

Restores airflow & heat transfer

Safe for aluminum or carbon steel tubes

Why External Cleaning Is Necessary For HRSG Tubes

Reduced back-pressure

Lower gas-side temperatures

Improved heat transfer

Extended tube life

Increased steam production

For Fin Fan Coolers

Improved air flow through fins

Lower fan power consumption

Lower process outlet temperature
