Abstract:
A plasma generator ignites and sustains a uniform and linear plasma near atmospheric pressure. The plasma generator is composed of two power supplies, a power divider, an array of transmission line tapers and an ignition resonator. One microwave power supply is used to drive the taper array and the other power supply drives the ignition resonator. The power divider splits the taper array power evenly and delivers it to each taper. A plasma is ignited by the ignition resonator and then the plasma propagates to the taper array. The taper array does not start a plasma by itself and the ignition resonator is provided to do so. Increasing the number of tapers increases the length of the plasma.
Abstract:
The present invention relates to a method and device for processing a gas by forming microwave plasmas of the gas. The gas that is to be processed is set in a two or three co-axial vortex flow inside the device and exposed to a microwave field to form the plasma in the inner co-axial vortex flow, which subsequently is expelled as a plasma afterglow through an outlet of the device. The device is provided with a microwave field choking effect by having a diameter of the exit channel larger than zero but smaller than 1/16 of the wavelength of the standing microwave within the microwave chamber and a length, ∈, of the exit channel that may correspondingly have one of the following ranges: from a factor larger than zero but smaller than (n+1/8), n G {0, 1, 2, 3}, of the wavelength of the standing microwave within the microwave chamber.
