烟煤

A low volatile bituminous coal was used as reburn fuel.

利用一种低挥发分烟煤作为再燃燃料，在煤粉携带炉中进行了该种煤再燃还原NO的实验研究。

In oxygen deficient high temperiture combustion, the amount of volatic material evolved influene the conversion of sulfur in coal, high volatile content restrains the oxidation of pyrite and iron sulfide , which causes compavatively large amount of iron sulfide left in char. At the condition of air coefficient α=0.4, the sulfur conversion is up to 87% for SHONGZHAO anthracite coal, 72% for FORGCHANG bituminous coal, and the conversion is compeleted within 0.5 see.

在高温贫氧状态下燃烧，煤中硫的释出率高于煤的燃烧率，高挥发份将抑制黄铁矿的氧化释放出来，即影响煤中硫的释出率，在过量空气系数为40％时，松澡无烟煤能达到87％的硫的释出率，丰城烟煤达到72％的硫的释出率。

沥青煤，烟煤，软煤

It is able to produce pyrolysis gas of high gas calorific value and light tar oil of low temperature with high production of gasified gas.

该产品是专门为燃用烟煤的用户设计的炉型，煤气热值相对于 KM1Q 系列较高，环保更可靠。

The research show that from anthracite, lean coal to bituminous, reaction rate become more and more large and ignition activation energy become more and more small; ignition activation energy falls and reaction rate increases as the volatile content increases;With the carbon content of dry ash-free basis increasing, ignition activation energy increases and reaction rate falls.

结果表明：从无烟煤，贫煤到烟煤，其反应速率越来越大，频率因子越来越小，着火活化能越来越低；挥发分增加，活化能减小，反应速率变大；干燥无灰基固定碳含量增加，着火活化能增加，反应速率减小。

Block coal, anthracite block is the best.

三、燃烧选用，以选择烟煤块、无烟煤块效果最佳。

Remove ash once a month when burning Shenmu soft coal block for the product.

本产品使用烧神木烟煤块时，需每30天清灰一次，否则易积灰，不传热。

The high rotten coal (including the anthracite and meager coal ) radioactive level is relatively low,( 238U: 29.1Bq/kg , 232Th: 25.9Bq/kg , 226Ra: 37.5Bq/kg), obviously lower than the radioactive levels of the brown coal and bituminous coal, and fluctuating range little relatively stable until Lincang uranium germanium colliery HeKai Tian little dragon's pool power plant make , investigate than right far correctly, prove natural radioactive nuclide (238U , 232Th , 226Ra ) than activity transformation in the course of utilizing and give locality radiate influence that environment bring.

高变质煤放射性水平相对较低，（238U：29.1Bq/kg、232Th：25.9Bq/kg、226Ra：37.5Bq/kg），明显低于褐煤和烟煤的放射性水平，且波动范围较小、相对稳定通过对临沧铀锗煤矿田和开远小龙潭电厂作出调查比对，说明了天然放射性核素（238U、232Th、226Ra）比活度在利用过程中的转移以及给当地放射环境带来的影响。

The combustion characteristic of briquet has been studied preliminarily with Dupont-2000 thermal gravity analyzer on this paper. The bituminous coal samples have both T1 and T2 characteristic temperatures, corresponding separately to losing sharp the weight of the samples.

本文使用热重分析仪对型煤的燃烧特性进行了初步探讨，烟煤样品在升温过程中，发生两次快速失重，对应的温度分别为T_1和T_2，由于制备型煤时，添加了无机粘结剂和无机固硫剂等无机物，导致制备型煤用的混合料的T_1比原煤降低，而剧烈燃烧温度T_2却比原煤升高。

The influence factors of the catalysed combustion process are discussed.

借助燃烧率测定，X射线衍射及差热分析等研究方法，讨论了无烟煤催化过程中的相关影响因素。

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。
