Microwave plasma slowing system for a plasma shutter comprises a waveguide-band transmission for interconnection of the system with a generator, and for letting waves from the generator into the plasma shutter, a bridge band interconnected with the waveguide-band transmission, two parallel band waistlines, interconnected by its one end with the bridge band, where the band waistlines are flat plates, where one of its sides is provided with tenons arranged side by side along the axis of the band waistlines with orientation in a such way, that the tenons arranged on the one side of the first band waistline placed in turns between the tenons arranged on the one side of the second band waistline, where the band waistlines are provided at the other end by mutually separated lockable electromagnetic oscillators.

A method of generating syngas as a primary product from renewable feedstock, fossil fuels, or hazardous waste with the use of a cupola. The cupola operates selectably on inductive heat alone, chemically assisted heat, or plasma assisted heat. Additionally, the operation of the cupola is augmented by the use of direct acting carbon or graphite rods that carry electrical current for additional heat generation into the metal bath that is influenced by the inductive element. The method includes the steps of providing a cupola for containing a metal bath; and operating an inductive element to react with the metal bath. Feedstock in the form of a combination of fossil fuel, a hazardous waste, and a hazardous material is supplied to the cupola. A plasma torch operates on the metal bath selectably directly and indirectly. Steam, air, oxygen enriched air, and oxygen are supplied in selectable combinations.

A gas treatment system includes a first scrubber, a regenerative catalytic oxidizer (RCO) that treats gas that passes through the first scrubber, a second scrubber that treats the gas that passed through the regenerative catalytic oxidizer, and a dielectric barrier discharge (DBD) plasma reactor that treats the gas that passed through the second scrubber. The regenerative catalytic oxidizer includes a two-bed regenerative catalytic reactor.
