利用工业分析值研究煤的燃烧特性

Research on the Combustion Characteristics of Coal Utilizing the Industry Analysis Values

文中提出了一个基于工业分析的煤燃烧特性参数ＺＭ，利用该参数判别煤的燃烧特性与实验确定的实际燃烧情况极为一致，在与其它不同燃烧指标结论比较后，笔者认为：在纯氧气氛中煤的燃烧是以均相着火方式发生的，并且参数ＺＭ可用来表征煤的均相着火性能，煤样在纯氧下的着火温度ｔｇ，ｉ和着火延迟时间τｉ均可通过经验公式予以计算。

The paper puts forward a parameter ZM of coal based upon the industry analysis, by which the combustion characteristics determined are quite consistent with the actual combustion status as found from experiments. After the comparison with the conclusion of other combustion indexes, the writer considered that, in the pure oxygen condition the combustion of coal takes place with the homogeneous-phase ignition mode, and the parameter ZM can be used to characterize the performance of the homogeneous ignition of coal. The ignition temperature tg, i and time delay of ignition in pure oxygeh τi both can be calculated with empirical formulas.
