Power Plant Cleaning: Turbines, Generators, Switchgear, and More
How dry ice blasting cleans rotating, electrical, and balance-of-plant equipment in place — without water, grit, or extended outage windows.
Power generation facilities lose capacity, efficiency, and reliability as carbon, oil mist, coal dust, fly ash, and surface oxidation accumulate on rotating, electrical, and auxiliary equipment. Traditional cleaning introduces water, solvents, drying delays, and disposal headaches that outage windows cannot absorb.
Where dry ice blasting fits in a power plant
- Turbines and compressors — inlet guide vanes, blades, casings
- Generators — rotors, stators, end windings
- Switchgear, MCCs, breakers — de-energized cleaning during planned outages
- Transformers, bushings, and bus ducts
- Motors and cable trays
- Inlet houses and filter plenums
Why it works around electrical equipment
Dry ice is a non-conductive dielectric medium. With proper NFPA 70E practices, LOTO, and minimum approach distances, crews clean switchgear, MCCs, and motors without disassembly — eliminating teardown and reassembly time during short outage windows.
What contamination it removes
- Carbon and tracking on insulators and windings
- Oil mist, grease, and varnish on rotors and stators
- Coal dust, fly ash, and biomass residue
- Salt deposits and surface oxidation
- Biological residue in inlet houses
Outage realities
Most plant cleaning scopes complete in 1–5 days depending on equipment count and access. We staff multiple crews for parallel work, bring our own diesel compressors, and integrate into the plant's existing safety and contractor management program.
Frequently Asked Questions
Is dry ice blasting safe on energized equipment?+
Dry ice is non-conductive and widely used on de-energized switchgear, MCCs, and motors. Live cleaning is performed only when written customer procedures and PPE permit it. NFPA 70E practices apply on every job.
Can you clean rotors and stators in place?+
In many cases, yes — removing oil, dust, and carbon tracking from windings without teardown, which saves significant outage time.
Do you work nuclear, coal, gas, and renewable sites?+
Yes. Combined-cycle, simple-cycle, coal, biomass, hydro, and balance-of-plant scopes — with site-specific safety orientation built into mobilization.
How fast can you mobilize?+
Planned outages are scheduled 60–180 days out. Forced outages typically get a crew on site within 24–72 hours when capacity allows.
