The present disclosure relates to a plasma reactor for plasma-based gas conversion comprising a plasma chamber and an effusion nozzle coupled to the plasma chamber. The plasma chamber comprises one or more gas inlets configured for introducing a feed gas into the plasma chamber, a first and a second electrode for generating gas discharge plasma, and at least one gas outlet opening for evacuating converted and unconverted feed gas from the plasma chamber. The effusion nozzle comprises a radial circumferential wall radially delimiting a gas-receiving cavity elongating along a central axis from a first end to a second end, and the gas-receiving cavity comprises an axial entrance opening at the first end for receiving the gas flow from the reaction chamber and an axial wall at the second end. The effusion nozzle is forming an extension of the second electrode or the effusion nozzle is forming the second electrode. The effusion nozzle further comprises one or more effusion openings for evacuating converted and unconverted feed gas from the gas-receiving cavity.

A method for controlling nitrogen oxide (NOx) includes adjusting a flow rate of d gas injected into an arc-type plasma generating device, and identifying a concentration of the generated nitrogen oxide, while adjusting an amount of energy per unit flow rate of the injected gas.

A high-purity NO.sub.2 gas generation apparatus, according to the present invention, comprises: an ozone gas generator; a nitrogen oxide gas generator containing NO; and a mixing unit for mixing ozone from the ozone gas generator and gas from the nitrogen oxide gas generator. Gas containing NO.sub.2 from the high-purity NO.sub.2 gas generation apparatus may be supplied to an apparatus for producing high-concentration activated water and fertilizer water. The apparatus for manufacturing high-concentration activated water and fertilizer water, according to the present invention, comprises: an upright cylindrical column forming a flow path in the longitudinal direction; a water supply unit positioned above the column and supplying water to the flow path; a gas supply unit positioned below the flow path and supplying gas containing NO.sub.2 gas; and a discharge port positioned at the lower end of the flow path and discharging a fluid.

The invention discloses a driving method for the synergistic combustion of fossil fuels and nuclear-chemical energy, pertaining to the field of fossil fuel combustion and nuclear energy utilization technology. The method comprises the following steps: introducing fossil fuel and combustion-supporting gas into an alternating electromagnetic field, causing collision of dissociated light nuclei, initiating nuclear fusion reactions, and releasing nuclear energy. Subsequently, the plasma-state fossil fuel and combustion-supporting gas, after leaving the controlled zone of the alternating electromagnetic field, undergo ultra-fast combustion within microseconds, significantly enhancing the ignition speed. Moreover, this method allows for the simultaneous release of chemical energy and nuclear energy during fossil fuel combustion, enabling the peaceful utilization of nuclear fusion energy and greatly improving the efficiency of energy release during combustion, leading to effective conservation of fossil fuel consumption.
