In the igniter, the metal shell of the inner layer pipe 4 or the outer layer pipe 5 acts as a negative electrode, however, the discharge between the positive electrode and the negative electrode is unstable, and combustion-supporting air needs to be conveyed, so that the ignition success rate is improved, but because the combustion-supporting air is conveyed to the combustion chamber by the combustion-supporting fan after passing through the kiln blanking cooler, a large amount of dust is contained in the combustion-supporting air, the combustion-supporting air pipe is easily blocked, and the ignition success rate is easily reduced after a period of use. And each time ignition fails, the purging time before and after the system exceeds 4 minutes, the temperature in the rotary kiln is fast reduced, the subsequent temperature rise needs longer time, the gas waste is caused, and the production efficiency of the rotary kiln is influenced. Therefore, it is necessary to further stably improve the ignition success rate and the production efficiency of the rotary kiln.
