Read MoreWang et al. l [11] studied high-pressure hydrogen pressure and combustion characteristics during spontaneous combustion through a series of experiments. Golub et al. [12,13] used nitrogen as a replacement for hydrogen and observed the fluid behavior of an unreactive gas released from a pipe through a jet experiment,
Read MoreBoth storage system related and coal-specific factors influence the risk of spontaneous combustion. Of the coal-specific factors, the content of volatiles appears to have a relatively strong impact on the propensity of coal to self-heat and ignite, as we have shown for the bituminous coal batches delivered to the Salmisaari storage silos.
Read MoreFor instance, Wang et al. (2008) fully studied the thermal behavior of both dry cotton and wet cotton by using C80 micro-calorimeter and confirmed that C80 can be used as an effective instrument to identify the cause of cotton spontaneous combustion. They found that dry cotton may not be the self-heating material.
