ABSTRACT:
The method and apparatus are for safely cleaning live equipment. The method comprises the steps of heating a water-based solution by means of an apparatus to produce superheated steam; grounding this apparatus; conducting the superheated steam through an insulated conduit; and concentrating this superheated steam into a pressurized jet at an output of the insulated conduit. After the step of grounding the apparatus, the method further comprises the step of applying the pressurized jet through the insulated conduit output, onto the live equipment to be cleaned.
