The present invention provides a plasma generating system that includes: a plurality of plasma reactors. Each plurality of plasma reactors includes: a waveguide for transmitting a microwave energy therethrough; a plasma chamber coupled to the waveguide and configured to generate a plasma therein using the microwave energy; a gas inlet for introducing a gas into the plasma chamber; an exhaust gas pipe for carrying an exhaust gas from the plasma chamber, wherein the plasma converts the gas into the exhaust gas; and a pressure control device installed in the exhaust gas pipe and configured to control a pressure of the exhaust gas in the exhaust gas pipe. The plasma generating system also includes a manifold coupled to the exhaust gas pipes of the plurality of plasma reactors and configured to receive the exhaust gas from the exhaust gas pipes.

Controlling exhaust gas pressure of a plasma reactor for plasma stability

A plasma generating system includes a waveguide for transmitting a microwave energy therethrough and an inner wall disposed within the waveguide to define a plasma cavity, where a plasma is generated within the plasma cavity using the microwave energy. The plasma generating system further includes: an adaptor having a gas outlet through which an exhaust gas processed by the plasma exits the plasma cavity; and a recuperator directly attached to the adaptor and having a gas passageway that is in fluid communication with the gas outlet in the adaptor. The recuperator recovers heat energy from the exhaust gas and heats an input gas using the heat energy.

Plasma reactors having recuperators

The present invention provides a plasma generating system that includes: a plasma cavity for generating a plasma therewithin by use of microwave energy; an adaptor electrically grounded and having a gas outlet through which an exhaust gas processed by the plasma exits the plasma cavity; and an ignition device mounted on the adaptor. The ignition device includes: a first electrode electrically grounded; and a second electrode electrically floating and configured to convert a portion of the microwave energy into an electrostatic discharge to thereby develop a voltage difference between the first and second electrodes, where the voltage difference generates a spark discharge between the first electrode and the second electrode to create the plasma.

Durable auto-ignition device for plasma reactor

A plasma generating system includes a waveguide for transmitting a microwave energy therethrough and an inner wall disposed within the waveguide to define a plasma cavity, where a plasma is generated within the plasma cavity using the microwave energy. The plasma generating system further includes: an adaptor mounted on a first side of the waveguide and physically separated from the waveguide by a first gap and having a gas outlet through which a gas processed by the plasma exits the plasma cavity; and an EM seal disposed in the first gap and configured to block leakage of the microwave energy through the first gap.

Plasma generating system having thermal barrier between plasma reactor and waveguide

The present invention provides a plasma generating system that includes: a waveguide for transmitting a microwave energy therethrough; an inner wall disposed within the waveguide to define a plasma cavity, wherein a plasma is generated within the plasma cavity using the microwave energy; a first gas inlet mounted on a first side of the waveguide and configured to introduce a first gas into the plasma cavity and generate a first vortex flow within the plasma cavity using the first gas, the first gas inlet having a through hole through which a gas processed by the plasma exits the plasma cavity; and a plasma stabilizer having a shape of a circular hollow cylinder and installed on a second side of the waveguide, an axial direction of the plasma stabilizer being in parallel to a rotational axis of the first vortex flow.
