System, method, and apparatus for an intense ultraviolet radiation source

An intense ultraviolet radiation source is disclosed that may be operated in substantially any arbitrary gas environment, without regard to a containment envelope for the ultraviolet radiation source. The intense ultraviolet radiation source can be generated by applying a pulsed or continuous electrical discharge to a partially ionized combustion flame via two electrodes. The combustion flame and electrical discharge can be focused, contained, or confined by gas pressure, electric fields, and / or magnetic fields. Optionally, the thermal energy in the flame and the electrical discharge power input may be augmented with an electromagnetic radiation source, such as a radio-frequency induction heater, a laser, or a microwave generator. Impurities may be placed in contact with or added to the fuel and / or the oxidizer to further alter the emitted ultraviolet radiation spectral brightness as needed. The ultraviolet source may be applied to the molecular dissociation of pollutants in exhaust gas streams of combustion systems. The efficient dissociation of such pollutants requires UV in the wavelength ranges of the vacuum ultraviolet band (100 nm-180 nm) and the UV-C band (180 nm-280 nm).
