Micropore double-electrode plasma assisted collision diffusion combustion device

Abstract

The invention discloses a micropore double-electrode plasma assisted collision diffusion combustion device. Gas ionization is carried out by using a micropore double-electrode structure with nanosecond pulse to form plasma, and low-temperature oxidation and combustion chain reaction of fuel are accelerated. The abovementioned device comprises a pulse power supply, a double-electrode structure anda closed container. The pulse power supply comprises a nanosecond pulse power supply converter, which can be connected with an alternating current and digital delay generator. The pulse power supply is electrically connected with the double-electrode structure, and the gas stored in the closed container can be sprayed to the double-electrode structure. The double-electrode structure comprises a double-layer metal sheet and single-layer medium, wherein the single-layer medium is arranged in the middle of the double-layer metal sheet, the metal sheet and the single-layer medium are both providedwith micropores, and the micropores are uniformly distributed in the metal sheet and the single-layer medium.
