The nozzle of the gasifier is simplified. The cold-flow field in the gasifier chamber is studied. The research shows that the chamber has recirculation along the whole length. The particles in the chamber perform a very good flowing characteristics even for the large particles of dp=150μm, and no abrupt change is observed. This is due to the operational pressure is high and the density of the gas is large there. The maximal reflux velocity of both phases, the reflux intensity, the concentrational distribution of particles, and the static pressure loss in the chamber are all related to following factors: the load of gasifier, the concentration of coal-water slurry, the diameter of the coal particle, the distribution ratio of oxygen in the two channels of the nozzle, and the angle of jet in nozzle.
