The main phenomenon of weathering and self heating of solid fuels is the low temperature oxidation of the combustible substance. Also of importance is the degassing and low temperature devolatilization of the solid fuel and the transport of water vapour through the solid fuel bed. Energy losses and the ecological aspects of solid fuel weathering (self heating, endogenous fires, gas explosions) are the main subjects of this work. A method of the energy consumption determination in the weathering process of solid fuel, treated as a physical and chemical process, by using the kinetic relations of the main phenomena is proposed.
