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.

本文对水煤浆气化炉喷嘴进行了简化处理，在此基础上，对气化室内的冷态流动过程进行了研究，发现：整个气化室都处于流动的回流区长度范围以内；水煤浆气化炉中，由于操作压力很高，气相密度很大，所以即使对于dp=150μm的较大煤颗粒，其对流体的跟随特性也很好，没有发生流动特性突跃的现象；两相的最大回流速度、回流强度，颗粒相的浓度分布，以及气化室内的静压力损失等，均与气化炉的负荷、水煤浆浓度、煤粒直径、O2在喷嘴两个流道中的分配比例、以及喷嘴的射流角等参数有关。
