Abstract

The invention discloses a microwave plasma combustion-supporting device based on a surface wave mode. The microwave plasma combustion-supporting device comprises a microwave source (1), a surface waveplasma generator (6), an air inlet system (7) and a combustion-supporting system (10), and is characterized in that a metal tube (18) is arranged on the surface wave plasma generator (6); the combustion-supporting system (10) comprises a discharge chamber (9) and a combustion chamber (11), one end of the discharge chamber (9) extends into the metal tube (18), and the other end of the discharge chamber (9) extends into the combustion chamber (11); and the discharge chamber (9) comprises an inner tube and an outer tube which are coaxially arranged together in a nested manner. According to the microwave plasma combustion-supporting device based on the surface wave mode, the problem that the size and shape of the combustion chamber are limited by a microwave resonance plasma combustion-supporting technology is solved, the discharge stability of surface wave plasma in the combustion-supporting process can be improved, and the service life of the surface wave plasma in the combustion-supporting process can be prolonged.

Description

technical field [0001] The invention specifically relates to a microwave plasma combustion-supporting device based on a surface wave mode, and belongs to the technical field of low-temperature plasma combustion-supporting. Background technique [0002] Currently, most of the world's energy comes from combustion. As environmental and energy issues such as smog and climate change become more severe, the demand for energy conservation and emission reduction in countries around the world has become particularly urgent. However, combustion systems such as gas turbines and internal combustion engines generally have the objective problems of low energy conversion efficiency and large pollutant emissions. One of the important factors is the high temperature of the combustion flame. High temperature combustion leads to increased heat loss in the combustion system and promotes the formation of nitrogen oxides. Therefore, low-temperature fuel-lean combustion by reducing the fuel-air ...
