Our power plant cleaning service is brought to all producers of electricity.Tweet
You might be a natural gas and/or fuel oil fired power plant operator and need a HRSG, fuel turbine, steam turbine, compressor or the inside of a lube oil tank cleaned. If so, dry ice blasting is the cleaning process with the least amount of damage risk available.
Dry ice blasting leaves behind no secondary waste stream. There is no need to worry about abrasive blast media causing damage at a later time, dry ice is not abrasive.
There could be a boiler, with tubes that have lost their effectiveness to transfer heat. Maybe the explosive you use to get your boiler clean isn't working so well.
Dry ice has no liquid state, imagine not having any liquid to contain, treat, or transport to a disposal facility. This cleaning process minimizes hazardous material disposal fee's. Dry ice sublimates instantly on impact from a solid to a gas. It does not promote corrosion.

Perhaps there is a generator scheduled to be overhauled at your coal fired facility or maybe an emergency repair is underway. What ever the case is, dry ice blasting is the most effective and safest way to clean a generator. The picture here shows the coils being dry ice blasted.
What? How can the high velocity dry ice pellets impacting the fragile insulation coating not cause damage?
If you look close you see a deflector at the end of the nozzle. The angle of the deflector is not great enough to cause sublimation, but it is enough of an angle that when the pellets impact the deflector they break up into tiny particles. The tiny particles are not heavy enough to penetrate the surface of the coating. This technique makes power plant cleaning by dry ice blasting very desirable. There are many surfaces in a power plant that need a more delicate approach. Dry ice blasting is an excellent choice for power plant cleaning.
The picture at left shows a steam turbine case mating surface being stripped of baked on boiled linseed oil.
This job used to take many man hours of scraping with scrapers and scrubbing with abrasive pads using stripping solutions. Great care was used not to scratch or gouge the surface.
Dry ice blasting gets power plant cleaning jobs done in minutes, leaving the surface exactly as it was before the boiled linseed oil was applied.
