A Discharge Plasma Assisted Combustion Flame Stabilizer

Abstract

A combustion flame stabilizer assisted by discharging plasma comprises a high-voltage electrode, a mixing cavity is formed in the high-voltage electrode, and an air inlet is formed in the outer wall side of the high-voltage electrode. An opening formed in the upper side is an air outlet, a quartz tube is arranged on the lower side, a copper ring ground electrode is fixed into the cavity through aquartz tube, an annular hydrocyclone is mounted at the position, above the copper ring ground electrode, of the inner wall of the high-voltage electrode, and a plurality of center current guide columns are formed in the position, corresponding to the annular hydrocyclone, in the high-voltage electrode. According to the flame stabilizer, gas fuel canbbe subjected to motivation, dissociation, ionization and other actions to generate the plasma, a large number of chemical active particles are included, the flame stabilizer can work at low oxygen and low pressure, and the combustion efficiency ofa combustor is further improved; by means of the structure, the energy exchange rate of gas backflow can be increased, and therefore the stability of flames is improved.

Description

technical field [0001] The invention belongs to the technical field of combustion devices, and in particular relates to a novel discharge plasma assisted combustion flame stabilizer for gas discharge plasma assisted combustion. Background technique [0002] Once the gas turbine combustor starts to work, it needs to maintain stable flame combustion under different working conditions. On the one hand, the gas turbine combustor must work with maximum efficiency within an appropriate and as large as possible oil-gas ratio range; on the other hand, in the combustion process, under the condition that the inlet air velocity is constant, the flame combustion must be stable, but due to the heat capacity The strength is high, and the inlet air velocity is relatively fast, which brings great resistance to the stability of the flame. For the aero-engine power combustion chamber, under the conditions of high airflow velocity, low total pressure and high total temperature, especially bec...
