Spontaneous combustion of carbonaceous stockpiles. Part I: the relative importance of various intrinsic coal properties and properties of the reaction system

摘要: Abstract The likelihood of a coal stockpile or carbonaceous waste dump undergoing spontaneous combustion is strongly influenced by factors that relate to both the intrinsic properties material itself, as well reaction system. An understanding these pre-requisite for simulation large-scale system with aim preventing containing this phenomenon. first part paper investigates range were considered be most critical in terms heat ‘generation’ bulk medium.
