When I meet the engine with its train of cars moving off with planetary motion —— or, rather, like a comet, for the beholder knows not if with that velocity and with that direction it will ever revisit this system, since its orbit does not look like a returning curve —— with its steam cloud like a banner streaming behind in golden and silver wreaths, like many a downy cloud which I have seen, high in the heavens, unfolding its masses to the light —— as if this traveling demigod, this cloud-compeller, would ere long take the sunset sky for the livery of his train; when I hear the iron horse make the hills echo with his snort like thunder, shaking the earth with his feet, and breathing fire and smoke from his nostrils（what kind of winged horse or fiery dragon they will put into the new Mythology I don't know）, it seems as if the earth had got a race now worthy to inhabit it.

当我遇见那火车头，带了它的一列车厢，像行星运转似的移动前进，——或者说，像一颗扫帚星，因为既然那轨道不像一个会转回来的曲线，看到它的人也就不知道在这样的速度下，向这个方向驰去的火车，会不会再回到这轨道上来，——水蒸汽像一面旗帜，形成金银色的烟圈飘浮在后面，好像我看到过的高高在天空中的一团团绒毛般的白云，一大块一大块地展开，并放下豪光来，——好像这位旅行着的怪神，吐出了云霞，快要把夕阳映照着的天空作它的列车的号衣；那时我听到铁马吼声如雷，使山谷都响起回声，它的脚步踩得土地震动，它的鼻孔喷着火和黑烟（我不知道在新的神话中，人们会收进怎样的飞马或火龙），看来好像大地终于有了一个配得上住在地球上的新的种族了。

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。
