The more bituminous blended in low volatile coal, the better the burnout characteristics would be.

分析结果表明：混煤的燃尽特性介于组成组分两种单煤之间，在低挥发分煤中掺入烟煤的量越多，其燃尽性能越好。

The samples used in the investigation include seven demineralized raw coals ranging from peat to anthracite in rank and three chars derived from two demineralized bituminous coals and one boghead coal, and their combustion characteristics are analyzed using TG-DSC techniques.

以煤阶从泥煤到无烟煤7个脱灰原煤及两个烟煤、一个腐泥煤制成的半焦作为燃烧试样，利用同步TG─DSC技术研究其燃烧特性，用一级反应动力学方程：1n－1n＝－E／＋1n处理所得实验数据。

该计算模式提供了一个独立于煤炭自然特性或煤中附加不可燃成分的有价值数据，已经证明了，若煤粉中挥发份超过0.12，存在爆炸风险。

Less dense types, such as sub-bituminous and lignite coal, can contain up to 50% water.

低浓度的煤炭，如亚煤烟煤和褐煤等，其含水量最高可达50%。

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。
