烟煤

The catalysed combustion process of anthracite by adding catalysers CaCO3,CaCO3＋BaCO3,CaCO3＋Sr(NO3)2, CaCO3＋BaCO3＋Sr(NO3)2＋Fe2O3 is studied in the papers.

与烟煤相比，无烟煤因其燃烧活性较差，一般不被水泥回转窑、予分解窑采用。

滚动炉排（该炉排将煤滚动燃烧，燃尽率高，彻底解决了侧密风）适用ⅡⅢ烟煤和煤矸石。

All the phenomena of experiment were analysed. The results show that under the condition of hot-blast air and oxygen enrichment, the combustion rate of single coal and mixed coal is increased, but the bituminous coal is better than anthracite coal.

在热风富氧的条件下，单种煤和混合煤的燃烧率随富氧率的增加都有提高，而且无烟煤燃烧率的提高幅度略高于烟煤。

Low rotten bituminous coal (jet coal, it glues coal to be and weak to glue coal), natural radioactive level lower,( 238U: 33.2- 50.0Bq/kg , 232Th: 52.5- 54.4Bq/kg , 226Ra: 30.6- 56.5Bq/kg ), obviously lower than the brown coal than activity, and the uranium , radium which the companion grew is in a basic balance, uranium , thorium are also in a basic balance.

低变质烟煤（包括长焰煤、不粘煤和弱粘煤）天然放射性水平较低，（238U：33.2～50.0Bq/kg、232Th：52.5～54.4Bq/kg、226Ra：30.6～56.5Bq/kg），比活度明显低于褐煤，且伴生的铀、镭基本平衡，铀、钍亦基本平衡。

The binder properties bear a linear relation to the content of ulminite in the maceral of corresponding brown coal.

煤岩学的初步研究表明，风化程度较高的烟煤、褐煤对应粘结剂性能较好，褐煤显微组分中，腐木质体的含量与煤对应粘结剂性能呈正相关。

It was found that tignite and its char have their NO re d uction efficiency higher than those of other coals and chars.The content of vola tile in coals,surface area of the chars and the content of metal catalyst in ash are all important factors affecting the NO reduction efficiency.

实验结果表明，褐煤及褐煤焦对NO的还原能力明显强于烟煤和烟煤焦，煤粉挥发分含量、煤焦颗粒的比表面积和煤灰中的金属氧化物含量都对NO还原有重要的影响。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
