With coal indirect liquefaction is exemple, dimensions is 5 million tons / year manufacturing unit, aerification is in with coal 2200-2500 10 thousand tons.

以煤间接液化为例，规模为500万吨/年的生产装置，气化用煤在2200-2500万吨。由此可见，我国在。。。。。。

Firstly the k-e two-equation turbulence model is used in numerical simulation of the flow field ,compared with the practical measures and tests, good accordance achives. This method can bring great convenience in analyzing aerodynamical field of boiler. Secondly the method of ash-composition, ash-melting-point, XRD is used in analyzing the phase transformation in the course of dynamic slagging test, so we can describe the process of slagging comparatively accurately. Last this paper introduces a kind of fuzzy mathematics model which comprises an assemblage combined by seven change factor.

接着采用标准k—ε双方程模型对炉内冷态空气动力场进行了数值模拟，并与实际锅炉燃烧器冷态调试试验结果对比，结果吻合较好，这为我们分析炉内流场提供了参考；其次对锅炉静态、动态特性试验，采用灰成分分析、灰熔点测试及X光衍射物相分析方法，较为准确的描述了实际锅炉结渣过程；为了准确的判断出水煤浆的结渣倾向，本文对锅炉结渣的七个影响因素提出了模糊综合判断模型，正确的反映出了该水煤浆的结渣倾向。

Characteristics of different dry coal beneficiation methods and advantages of air dense medium fluidized bed were introduced in paper.

论文讨论了洁净煤分选技术的意义和现状、各种干法分选方法的特点以及空气重介质流化床选煤技术的优越性。

The paper presents a more detailed discussion of the significance and present situation of coal separation and the latest development of air heavy medium fluidized bed coal separation technology.

详细讨论了选煤的意义和现状以及空气重介质流化床选煤技术目前的发展。

The coal sample was combusted in the oxygen bomb containing ammonium carbonate solution and enough pressed oxygen.

在加有(NH4)2CO3溶液和过量氧气的氧弹中燃烧煤样，释放的氯被(NH4)2CO3溶液吸收，过滤溶液后，采用离子色谱外标法测定滤液中氯的浓度，最后计算出煤中氯的含量。

In this process asphaltene is main product of Xinzhuang coal.

可见对煤浆粘度变化的研究在煤液化技术开发中是相当重要的。

An Experimental Investigation of the Autoignition Chemistry of Primary Reference Fuels and their Blends

洗精煤是焦化厂的主要原料，多在煤场露天存放，煤的自燃性对焦化厂储煤形成了很大的隐患。

We sat before a little fire, with two bricks put within the rusted grate, one on each side, to prevent its burning too many coals; until another debtor, who share the room with Mr. Micawber, came in from the bakehouse with the loin of mutton which was our joint-stock repast.

我们坐那儿烤着火，把两块煤坯搁进生锈的炉膛里，一边一块，好省点煤；这时又来了一枚穷光蛋，就是跟密考伯先生合住那位，从小吃店带了羊里脊来了，我们就有饭同食了一顿。

If we try,we'll certainly find cheap ways to transform North America's 1 trillion bbl. worth of coal into crude as well..

此外，我们也能够以比较廉价的方式将北美地区一万亿桶煤转化为能替代原油的液化煤。

Feed mechanism: up roller, middle flashboard and down bell jar mechanism is adopted, which is advanced both home and abroad.

加煤机构：采用国内外较先进的上滚筒中插板下钟罩加煤机构，具有操作简单、维修方便、气密性好等特点。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
