Problems solved by technology

Due to the low oxygen content in the high altitude, the pressure and temperature are low, and because the compressor is in a windmill state, it cannot provide high-pressure air to the combustion chamber. These factors have increased the difficulty of ignition. Challenges require a more reliable ignition method

Abstract

The invention relates to a directional spinning plasma combustion-supporting system, which comprises a hollow shell, a nanosecond pulse plasma power source and a plasma actuator which is connected to the nanosecond pulse plasma power source, wherein a gas collection device and a gas inlet are respectively arranged at the top end and the lower end of the hollow shell; a combustion zone and a premixing zone are formed in the hollow shell from top to bottom; the plasma actuator and the nanosecond pulse plasma power source are respectively arranged inside and outside the hollow shell; the gas inlet is communicated with the gas collection device by sequentially passing the premixing zone and the combustion zone. The invention provides the directional spinning plasma combustion-supporting system which is capable of improving the combustion-supporting performance and the energy efficiency ratio.

Description

technical field [0001] The invention relates to a plasma combustion-supporting system, in particular to a directional spin plasma combustion-supporting system. technical background [0002] The basic principle of plasma combustion is to use the chemical activity of the non-equilibrium plasma to improve the ignition performance and combustion characteristics of the fuel. Or energy transfer and "deformation", resulting in the relaxation, breakage or cracking of molecular bonds into free radicals, a large number of active atoms and groups are generated during the discharge process, which affects the chemical balance of the combustion system and accelerates the chemical kinetic process of combustion. [0003] The use of plasma ignition and combustion will have many advantages: plasma can not only quickly heat the gas flow, but also generate a large number of chemically active species, such as molecules and free radicals in excited states, which can achieve a wide range of igniti...
