  8. This flexion of graph can be defined as criterion of coal ignition character under excessive oxygen supply. based on viewpoints of coal ignition, we put forward assumption aiming at ignition character of coal with excessive oxygen. in this thesis, with comparison of average temperature increase among eleven kinds of coal, the following are obtained : homogeneous ignition happens when coal has higher volatile matter and there is a approximative direct - ratio relationship between temperature hoist before flexion and content of volatile matter ; on the other side, heterogeneous ignition occurs for the coal with lower volatile matter content because of collective influence of volatile matter and fixed carbon combustion, and one - to - one relationship between temperature increase before flexion and content of volatile matter does not exit

    以煤著火性質研究的觀點為基礎，對煤在過氧條件下的著火性質提出假設，通過11種標準煤樣在過氧條件下燃燒實驗，對比了拐點前後平均溫升與煤樣成分的關系，證實了揮發分含量較高的煤在過氧條件下發生均相著火燃燒，拐點前後量熱系統的溫升分別與揮發分和固定炭的含量成近似正比的關系；而揮發分含量較低的煤在過氧條件下發生非均相著火燃燒，拐點之前量熱系統的溫升由於受到揮發分和固定炭同時燃燒的影響，因而不存在溫升與揮發分含量之間單一的對應關系。
