Glacier Blast's solution, dry ice blasting, is the recommended method for generator cleaning.Tweet
Most operators understand as well or better than Glacier Blast Inc., how important generator cleaning is to the efficient operation of their plant. Never the less our desire is to point out the detriments a dirty generator poses to the smooth generation of electricity and the solution to the problem.
Dirt itself is abrasive and shortens the life of bearings, bushings, gears etc. As the accumulation of dirt builds on the coils in the generator, the ability of the cooling air flow to transfer heat out of the generator decreases.
When this happens, a temperature increase is caused in the coils themselves. The temp rise increases resistance. Increased resistance causes a greater temp increase.
Several things start to happen as the generator approaches and moves beyond its maximum designed operating temperature.
Clearance between the stator and rotor change. If the designed clearances are exceeded output efficiency is lost.
Heat is adversely affecting the bearings in the generator. The lubrication loses its viscosity, causing more friction and even more heat. In severe cases carbon develops and destroys the lube completely.
The necessity of generator cleaning has been shown and logically proven. Glacier Blast's solution, dry ice blasting, is the recommended method for generator cleaning. But, why the recommended dry ice blasting method?
The dry ice blasting method is not abrasive, no abrasive blast media left behind to cause long term damage to motors, pumps, switches, bearings, gears etc., no water left behind to promote corrosion and no secondary waste stream to cleanup or dispose of after the job is completed. Dry ice blasting is recommended and approved by all generator manufacturers.
