The theories on pyrolysis and coking and hydrogenation of heavy oil are used to know the liquefaction and gasify and coking of coal. 3. The results of particle feeding in the hot plasma jet (1) By using the cold state of spraying the diesel oil mist transversely in the air flow at the subsonic and ultrasonic speed to imitate the stress condition and motion trace of coal powder in the plasma jet, it shows that with the speed of air flow changed from subsonic speed to ultrasonic speed, the uniformity of mixture between the coal powder with certain speed and air flow becomes worse, mixture length becomes shorter, which agrees with the law of momentum transfer.
