This paper discussed the thermal equilibrium and critical condition in exothermic reaction system, and deduced the values of dynamic parameters such as the judging criterion for thermal runaway, the ignition temperature and extinction temperature in the critical state of thermal runaway when there is no consumption of reaction materials
摘要討論化學放熱系統的熱穩定性和臨界條件，用化學反應物無消耗的假設推導化學放熱系統熱失控（熱爆炸）時的動力學參數臨界值，得到熱失控的判據、臨界點火溫度和熄火溫度。 -
Although oil is used only in the case of ignition and low load operation, the amount is very great. in order to save the precious and expensive oil, a novel technology, induction - heating multi - stage free - oil ignition technology of pulverized coal ( mfit ), is brought forward in this thesis. based on the study of ignition mechanism of coal, ignition criterion, heating method and ignition theory of pulverized coal ( pc ), mfit integrates hot - wall ignition technology, induction heating technology and multi - stage ignition technology
為降低電站鍋爐點火成本和低負荷運行費用、解決電站鍋爐點火用油和低負荷助燃用油居高不下的問題，在分析研究煤的著火機理、著火判據、加熱方式和煤粉的點燃理論的基礎上，本文將熱壁面點火、感應加熱、多級點火等過程有機地結合起來，進行了感應加熱煤粉多級無油點火的試驗研究。 -
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。
