Iron sulfide

The factors affecting the spontaneous combustion of iron sulfide under natural conditions are as follows:

The oxidation and heat dissipation of iron sulfide in the air are the internal factors that cause spontaneous ignition accidents. Continuous oxygen supply and easy heat accumulation are external factors of iron sulfide spontaneous combustion. Experiments have shown that the compounds produced by sulfidation of iron sulfide are highly active and have high natural oxidation activity. They react quickly with oxygen in the air at room temperature and release a large amount of heat at the same time.

Using iron sulfide sulfide as a typical sample, we studied the effects of ambient temperature, wind speed, vulcanization time, exposure area and iron sulfide quality on the oxidation temperature rise characteristics. The influence of ambient temperature on the heating rate is not clear, but the wind speed has the dual effect of promoting and inhibiting the spontaneous combustion process of iron sulfide. When the wind speed is 1.5m/s, the oxidation heat dissipation is strong, the vulcanization time is long, and the exposed area is large, and the iron sulfide will accelerate The oxidation temperature rise process, on the contrary, will reduce the spontaneous combustion tendency of iron sulfide.

The above is an introduction to the influencing factors of spontaneous combustion of iron sulfide under natural conditions. For more information, please click on our official website, thank you for reading.
