Abstract: Approaches herein provide a system for determining whether one or more consumable parts of a plasma device has been removed or replaced while the plasma device and associated sensors lie dormant or are no longer receiving data, e.g., when the plasma device is power-off. The approaches herein determine whether certain types of data stored in a controller's memory are still valid, for example, for the purposes of determining degradation and/or end-of-life of the consumable parts. In the case that one or more consumable parts has been serviced or replaced, the data stored in the controller memory may no longer be considered valid for the consumable part(s). In one approach, the controller determines a status of a switch or a conformal film in the device following start-up, and determines, based on the position of the switch or the conformal film, whether the consumable part has been removed or replaced.

Abstract: A high power DC steam plasma torch system (S) includes a steam plasma torch assembly (1) wherein superheated steam (46) is used as the main plasma forming gas, thereby resulting in a very reactive steam plasma plume.
