The heat of wetting and its effect on coal spontaneous combustion
In this study, the effect of the heat of wetting (Hw) of coal on its spontaneous combustion was investigated. Specifically, the effects of the amount of water used in the wetting (W), temperature (T), and particle size (PS) on the wettability and exothermic behavior of a coal sample were examined us...

| 520 | |a In this study, the effect of the heat of wetting (Hw) of coal on its spontaneous combustion was investigated. Specifically, the effects of the amount of water used in the wetting (W), temperature (T), and particle size (PS) on the wettability and exothermic behavior of a coal sample were examined using a C600 high-precision calorimeter. The trends of the Q curves under various conditions (W, T, and PS) were analyzed. The results show that the amount of Hw decreased as T increased. The smaller the PS of a coal specimen was, the higher the amount of Hw was. Additionally, a decrease in PS led to an increase in the Hw release rate (HRR). Due to the generation and accumulation of Hw, the oxidative heat storage system of coal is promoted, which accelerates the oxidative spontaneous combustion of coal at low temperature. | ||

Specifically, the effects of the amount of water used in the wetting (W), temperature (T), and particle size (PS) on the wettability and exothermic behavior of a coal sample were examined using a C600 high-precision calorimeter. The trends of the Q curves under various conditions (W, T, and PS) were analyzed. The results show that the amount of Hw decreased as T increased. The smaller the PS of a coal specimen was, the higher the amount of Hw was. Additionally, a decrease in PS led to an increase in the Hw release rate (HRR). Due to the generation and accumulation of Hw, the oxidative heat storage system of coal is promoted, which accelerates the oxidative spontaneous combustion of coal at low temperature.

The heat of wetting and its effect on coal spontaneous combustion |
| abstract |
In this study, the effect of the heat of wetting (Hw) of coal on its spontaneous combustion was investigated. Specifically, the effects of the amount of water used in the wetting (W), temperature (T), and particle size (PS) on the wettability and exothermic behavior of a coal sample were examined using a C600 high-precision calorimeter. The trends of the Q curves under various conditions (W, T, and PS) were analyzed. The results show that the amount of Hw decreased as T increased. The smaller the PS of a coal specimen was, the higher the amount of Hw was. Additionally, a decrease in PS led to an increase in the Hw release rate (HRR). Due to the generation and accumulation of Hw, the oxidative heat storage system of coal is promoted, which accelerates the oxidative spontaneous combustion of coal at low temperature. |
