Microwave adapting plasma torch module

  • US Patent No. 9681529
  • Issued: June 13, 2017
  • Status: Active

A plasma torch module combining arc and microwave discharges is disclosed. One embodiment serves to enhance the size and enthalpy of the plasma torch and has a very large operational range of the airflow rate, from subsonic to supersonic flow speed. Increase of airflow in the torch operation can increase not only the size of the torch plasma and the cycle energy of the arc discharge but also the lifetime of the torch module and the torch can operate stably with very low airflow.
