Systems for generating microwave plasma from a combustion flame. The present invention provides a microwave plasma nozzle that includes a hollow cylindrical housing through which combustible material flows, and a rod-shaped conductor disposed in the housing. A portion of the rod-shaped conductor extends into a microwave cavity to receive microwaves passing in the cavity. The rod-shaped conductor transmits microwaves along the surface thereof, and has a distal end disposed in proximity to and surrounded by a proximal end portion of the housing. During operation, a combustion flame is formed in proximity to the proximal 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.
