Nozzle for generating microwave plasma from combustion flame

A nozzle for generating a combustion flame and plasma from microwaves and the combustion flame, comprising:

• a hollow cylindrical housing for having a gas flow therethrough;
• and
• a rod-shaped conductor disposed in the housing and operative to transmit microwaves along a surface thereof, the rod-shaped conductor having a distal end disposed in proximity to and surrounded by a distal end portion of the housing, the rod-shaped conductor being a tube for having a flow of combustible material therethrough,
• wherein a combustion flame is formed in proximity to the distal end of the rod-shaped conductor and the microwaves transmitted along the surface heat up the flame to generate plasma in proximity to the distal end of the rod-shaped conductor during operation.

A plasma generating system, comprising:

• a microwave generator for generating microwaves;
• a power supply connected to the microwave generator for providing power thereto;
• a microwave cavity;
• a waveguide operatively connected to the microwave cavity for transmitting the microwaves thereto;
• an isolator for dissipating microwaves reflected from the microwave cavity;
• and
• a nozzle secured to the microwave cavity and including:
• a hollow cylindrical housing for having a flow of combustible material therethrough;
• and
• a rod-shaped conductor disposed in the housing and operative to transmit microwaves along a surface thereof, the rod-shaped conductor having a distal end disposed in proximity to and surrounded by a distal end portion of the housing,
• wherein a combustion flame is formed in proximity to the distal end portion of the housing and the microwaves transmitted along the surface heat up the flame to generate plasma in proximity to the distal end of the rod-shaped conductor during operation.
