Experimental study on inhibition of coal spontaneous combustion by carbon dioxide and nitrogen
Energy Sources, Part A: Recovery, Utilization, and Environmental EffectsInjecting CO2 and N2 to reduce the concentration of O2 in the air is a commonly used measure to prevent coal spontaneous combustion (CSC). To study the difference in inhibitory effects of CO2 and N2 on coal oxidation, experiments in this study were ...

A REVIEW OF SPONTANEOUS COMBUSTION OF COALS
2022Coal is one of the carbonaceous materials which, under certain conditions, can combust spontaneously as a result of its oxidation with atmospheric oxygen. Coal oxidation is an irreversible exothermic reaction and its rate increases with temperature. In mines or in storage, the deficiency of the heat dissipation capacity of the coal bulk with respect to

Study on Spontaneous Combustion of Coal Underground
Journal of the Fuel Society of Japan, 1957石炭の自然発火は現在まで主として化学的の面より研究されてきたが炭鉱内においておこる坑内自然発火の場合はその原因になる因子が非常に多く, この原因を発見することが困難である。従つて自然発火の早期発見も困難であつた。自然発火の早期発見に関しては現在まで臭気, 湿度の変化, 温度の上昇, 特殊指示ガスなどがその要素となつていたが, これらの方法はいずれも適確な予知ができず, また発見された時はもうすでにかなり自然発火が進んでいるという状況である。筆者は本文中において温度変化による発見の方途を一歩進めて炭層温度, 炭壁温度, 気流温度の相関関係から自然発火を予知する方法を述べるとともに, アスファルト乳剤塗布による自然発火防止の基礎実験について述べる。
