Abstract

The invention discloses a dielectric barrier discharge plasma axial rotational flow device which is used for stabilizing and supporting combustion of a burner. The device comprises a plurality of groups of plasma exciters, a nozzle outlet segment and a high-voltage power supply, wherein the plurality of groups of plasma exciters are uniformly distributed on the nozzle outlet segment along a circumferential direction. By applying plasma excitation of appropriate strength at the nozzle outlet segment of the burner, on one hand, the device can have an effect of increasing rotational flow of air, on the other hand, active radical is generated by ionization of the air, so that the effects of stabilizing and supporting combustion and improving combustion efficiency are achieved, and the device is favorable for solving the problems of aviation gas turbine blowout, and difficulty in ignition and combustion instability during combusting low-heat value gas of a ground gas turbine. The dielectric barrier discharge plasma axial rotational flow device has the advantages of simple and compact structure, rapid reaction, low energy consumption and the like.

Description

technical field [0001] The invention relates to the field of advanced combustion technology, in particular, it is a combustion-supporting device for improving gas fuel combustion efficiency and combustion stability, which can be used in aviation, chemical industry, power generation, metallurgy and other industries. In particular, it relates to a device for stabilizing and supporting combustion of dielectric barrier discharge plasma. Background technique [0002] As we all know, if the aviation gas turbine fails to ignite after it is turned off in the air, it will often cause a great flight accident. Due to the thin air at high altitude, the low oxygen content in the air, and the low pressure and temperature, these factors increase the difficulty of ignition. Therefore, it poses a great challenge to the stable combustion and ignition performance of the aviation gas turbine combustor, and more reliable methods are required. Stable combustion and ignition device. [0003] Som...
