Streszczenie
Even during normal operation but also due to unsuspected events like fires industrial devices get dirty. These
pollutions may cause efficiency decrease, operational problems and unsightly appearance. To prevent these undesired
phenomenon, various cleaning methods were developed. Dry ice blasting is one of them, which can be easily applied in wide
range of purposes. The method is similar to the sanding, but the dry-ice particles are used as the abrasive. Dry-ice blasting
process depends on many operational parameters like air pressure, dry-ice mass flow rate, nozzle-surface distance, cleaning
angle or dry ice granulation. Impact of these parameters on the cleaning velocity were determined.
