Abstract
A microwave activated gas generator in which microwave energy is supplied to an activated gas formation region through which a gas to be activated flows in a high-velocity stream. The stream is disturbed within or proximate the activation region to form a downstream stagnation region within the activated gas formation region to encourage microwave gas activation for efficiently coupling power to the gas to form a high-volume, high-velocity activated gas stream.
Claims26
A microwave activated gas generator, comprising:
- means for supplying microwave energy to an activated gas formation region;
- means for flowing gas to be activated through said activated gas formation region;
- and
- means for disturbing the flowing gas stream to form a downstream stagnation region in said activated gas formation region for encouraging microwave gas activation to effectively couple power to the gas for forming a relatively high volume of activated gas in the gas stream.
A microwave activated gas generator, comprising:
- a microwave waveguide adapted at one end to receive microwave energy and having an activation region for coupling the energy to a gas to be activated;
- a gas flow tube passing transversely through said activation region for carrying a gas to be activated into and through said region at high velocity;
- and
- an object placed in said tube to disturb the flow in said activation region for creating a downstream stagnation region to encourage gas activation in the activation region.
A microwave activated gas generator, comprising:
- a microwave waveguide adapted at one end to receive microwave energy and having an activation region for coupling the energy to a gas to be activated;
- a gas flow tube passing transversely through said activation region for carrying a gas to be activated;
- means for recirculating gas through the activation region in said gas flow tube at high velocity;
- and
- an object in said tube and spaced from the tube walls at least partly upstream of said activation region for disturbing the flow in the center of said tube in said activation region to encourage activation in the disturbed flow region for cooling the tube walls to allow more energy to be coupled to the gas for more efficient activated gas formation.
A microwave activated high velocity gas generator comprising:
- an activated gas formation region;
- means for supplying microwave energy to said formation region;
- means for introducing a flow of gas into said formation region;
- a processing area spaced from said formation region for utilizing the activated gas;
- means for disturbing the flow of gas in said formation region to form a downstream stagnation region in said formation region to encourage gas activation in the formation region;
- and
- a high velocity pump for moving activated gas to said processing area by convection while the remains activated.
