Abstract

When washing objects, such as turbine compressors, which operate with large quantities of air and are therefore internally soiled by and coated with contaminants carried by the air, finely-divided liquid is sprayed onto and through the object. The liquid is finely-divided to a degree at which the particles of the liquid will follow the same routes to and through the object as those previously taken by the air-borne contaminants. The quantities of finely-divided liquid are sprayed through at least one nozzle toward and through the object at an overpressure within the range of 50-80 bars at a liquid particle size in the range 250-120 .mu.m and with a total volumetric flow through the nozzle or nozzles within the range of 0.5-60 l/min., and with a liquid particle velocity of 100-126 m/sec.
