Double-channel plasma ignition burner

The double-channel plasma ignition burner comprises an outer cylinder, an ignition cylinder arranged in the outer cylinder in a sleeved mode and a plasma generator, the ignition end of the plasma generator is inserted into the ignition cylinder, a main cavity and a flow dividing cavity are formed in the outer cylinder, and the main cavity and the flow dividing cavity are arranged in a separated mode through a partition plate; the main cavity and the flow dividing cavity extend along the axis of the outer barrel, the ignition barrel is arranged in the main cavity, and an adjusting plate used for controlling air inlet of the flow dividing cavity is arranged on the face, close to the flow dividing cavity, of the partition plate. According to the double-channel plasma ignition burner, the ignition air speed requirement of low-volatile meagre coal and high-moisture lignite can be met, and the phenomenon of coking of the ignition cylinder can be avoided. 本发明公开了一种双通道等离子体点火燃烧器，包括外筒、套设于外筒内的点火筒和等离子体发生器，等离子体发生器的点火端插入点火筒
