摘要
分析了中国不同煤种、不同成煤时代炼焦煤的煤灰成分特性及其变化规律,指出煤灰成分对炼焦煤性质的影响实际上与沉积环境对炼焦煤性质的影响是密不可分的;部分矿区炼焦煤的焦炭热反应活性强,不仅与煤灰中碱性元素含量高有关,更主要是由于其沉积环境所造成。
This thesis analyzed the characteristics and change law of the ash composition of Chinese coking coal from different coal classed and different geological ages, and it was pointed out that how the ash composition affected the properties of coking coal was closely related to the sedimentary environment. In some mine areas, the high thermal reactivity of coking coal was related to not only the high alkaline elements contents but also the sedimentary environment, which was even regarded as a more important factor.
