Rotary gliding arc plasma fuel oil splitting decomposition head of aero-engine combustor

TLDR: In this paper, a rotary gliding arc plasma fuel oil splitting decomposition head of an aero-engine combustor was proposed to improve the uniformity that fuel is mixed with air and producing active particles.

Abstract: The invention provides a rotary gliding arc plasma fuel oil splitting decomposition head of an aero-engine combustor. The two end surfaces of a swirler are correspondingly connected with the front endand the rear end of an anode venturi-tube; a bell mouth mouting seat is matched with a supporting surface of the head of a combustor combustion liner of an engine; an outer layer bell mouth is mounted in a mounting groove of a bell mouth mouting seat and a cathode inner layer bell mouth is attached to the inner surface of the bell mouth mouting seat; the anode venturi-tube is located in the combustor combustion liner of the aero-engine; one end of a cable is mounted on the anode venturi-tube and the other end of the cable is connected with a power supply. The splitting decomposition head is capable of improving the uniformity that fuel is mixed with air and producing active particles capable of accelerating the combustion chemical reaction, so that the problems of low combustion efficiency, flameout caused by poor oil resources, ignition at high altitude and uneven temperature field of a combustor outlet port of the aero-engine under special conditions can be solved, and the splittingdecomposition head has the characteristics of being capable of splitting the fuel oil efficiently and producing a large amount of active particles, simple in structure and strong in versatility.
