Coal spontaneous combustion often occurs in storage processes, especially for low-rank coal with high volatile materials, which may lead yard caught fire and thermal energy losses. Therefore, it is important to accurately predict the tendency under status real time. In order determine ignition point, existing methods are all using pulverized samples, adding special oxidant artificially then hea...

Spontaneous combustion during coal mining operations is a major problem that affects the health and safety of workers causes environmental problems. The phenomenon associated with presence coal, shale, pyrite. In 2020, premature detonation incident occurred at an iron ore mine where waste material contains black carbonaceous shale units known to be spontaneous propensity properties samples shal...

Research has been conducted toward developing technology for co-firing of coal with municipal solid waste (MSW) in order to reduce emissions of chlorinated organic compounds, particularly polychlorinated dibenzo-p-dioxins and furans (PCDDs and PCDFs). Previous benchand pilot-scale research has shown that presence of SO2 can inhibit the PCDD and PCDF formation, and suggested cofiring high-sulfur...
