Coaxial resonant microwave discharge plasma large-scale high-efficiency combustion-supporting device

Abstract

The invention discloses a coaxial resonant microwave discharge plasma large-scale high-efficiency combustion-supporting device in the technical field of coaxial resonant microwave discharge plasma large-scale high-efficiency combustion supporting. The device includes a pulse microwave generator, a power display and a plasma generator; and the pulse microwave generator includes a microwave signal generator, a pulse modulation generator and a power amplifier. Through the utilization of microwave pulse resonance as a discharge driver, the tip of the tungsten filament of a U-shaped tungsten filament electrode can generate a locally enhanced electric field, so that gas discharge can be generated, plasma can be generated, particles having chemical activity can be massively generated, and the plasma and the combustion state in adjacent areas of the plasma can be changed; and gas turbulence levels can be enhanced by the wave disturbance formed by the diffusion of high-energy particles, so thatthe atomization, gasification and the mixing with air of fuel oil can be promoted, the contact area of flame front and fuel can be increased, and therefore, the purposes of enhancing combustion stability, rising combustion efficiency and reducing exhaust pollution can be achieved.

Description

technical field [0001] The invention relates to the technical field of large-scale and high-efficiency combustion-supporting coaxial resonant microwave discharge plasma, in particular to a large-scale and high-efficiency combustion-supporting device for coaxial resonant microwave discharge plasma. Background technique [0002] Plasma is rich in active particles, such as ions, atomic groups, atoms and electrons, etc., and has high physical and chemical activity. Its high-temperature thermochemical action can effectively promote the formation of two-component fuel with ignition point, thereby improving the reaction degree of fuel mixture. It has high application value in auxiliary combustion. Plasma is a quasi-neutral system composed of a large number of charged positive, negative and neutral particles. It is a fourth state of matter other than solid, liquid and gas produced under high temperature or other specific excitation conditions. As the fourth state of matter, plasma ...
