Background

Different from the traditional pulverized coal burner, the plasma igniter ignites pulverized coal by means of high-temperature (4000-12000K) plasma generated by a plasma generator, belongs to an internal combustion type burner, ignites the pulverized coal by using the high-temperature plasma at the initial stage when the pulverized coal enters the igniter, ignites the pulverized coal in the burner in a graded manner, amplifies the flame in a graded manner, and can form the flame with the length of 3-10 meters at the nozzle of the burner. The quality of the ignited coal powder is about 5 to 15t/h, and the power of the plasma gun is only 50 to 300KW; the trick is mainly classified ignition and gradual flame amplification.

However, when the temperature is too low, the plasma igniter is not easy to ignite, and the normal operation of the equipment is affected. To this end, we propose a pre-ignition plasma igniter.
