the high temperature and high enthalpy plasma produced by plasma generator is introduced into the central combustion chamber of multi-channel burner through the channel, which realizes the effective contact between high temperature plasma and air, coal or air coal mixture. the high temperature makes the pulverized coal particles rapidly rise and burst. after releasing a large amount of coal powder volatilization, it is ignited and injected into the kiln quickly, thus realizing the ignition combustion of coal, after the temperature in the rotary kiln reaches a certain temperature, that is, after the flame of stable combustion is formed, the plasma generator will be stopped. According to the normal operation requirements of multi-channel burner, the amount of pulverized coal will be increased gradually to realize the combustion of pulverized coal.

(1) the intelligent plasma ignition device is combined with the multi-channel burner of rotary kiln, only one device is used

the functions of different stages, such as ignition, stable combustion and normal combustion, can be completed;

(2) the technology is simple, easy to operate, safe and reliable, and the ignition temperature rises quickly and the heat efficiency is high;

(3) the oil-free ignition is realized, and a large amount of ignition oil is saved;

(4) It can better adapt to the requirements of the temperature rise curve of rotary kiln, especially in the early stage of ignition

the degree of fit is far superior to the ignition of oil gun and wood, which is convenient for temperature control and more favorable for protecting kiln bricks;

(5) the burning rate of plasma burner is high, which saves coal powder compared with conventional oil coal combustion, reduces environmental pollution and reduces

Cost;

(6) It has the function of reducing NOx, anaerobic combustion in advance, and plasma oil-free ignition technology for cement industry

Ignition brings new ideas and changes, and will surely realize the new situation of energy saving in cement industry.


the technology is used to improve the existing rotary kiln burner, which has a broad market prospect, huge potential for energy saving and obvious economic benefits.
