Comparison and analysis of spontaneous combustion control between coal storage silos and biomass silos

Abstract

Spontaneous combustion often occurs when carbonaceous materials are stored for a long time. Up to now, domestic and foreign scholars have done a lot of research on the spontaneous combustion mechanism of coal and biomass fuel, monitoring methods and prevention measures, and achieved fruitful results. It is worth noting that coal and biomass are not the same type of energy, but the internal mechanism and external performance of spontaneous combustion of the two are very similar, and both involve complex physical and chemical reactions. At present, very fruitful results have been achieved in coal spontaneous combustion monitoring and fire prevention in mine, but the spontaneous combustion research around coal storage silos and biomass silos is insufficient, and the spontaneous combustion monitoring and fire prevention technology for them is relatively backward. Therefore, by summarizing and comparing the relevant work in recent years, this paper aims to sort out the similarities and differences of the occurrence mechanism, monitoring methods and prevention measures of the two, explore the technologies and theories that can learn from each other, promote the progress of the two in the study of spontaneous combustion mechanism, and promote the development of more advanced spontaneous combustion monitoring and fire prevention technology. And the application in the mine-out area, coal storage silo, biomass silo and other scenarios, to provide theoretical and technical references for the future safe storage of coal and biomass.
