Heterogeneous combustion or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species. The release of heat can result in the production of light in the form of either glowing or a flame. This book presents topical research data in this field of study including transient modelling in heterogeneous combustion; combustion-based formation of dioxins and dioxin-like compounds; the surface chemical reactivity of combustion particles; a mathematical model of combustion wave processes in a heterogeneous medium with chemical reactions in the gas phase; residential coal combustion; and the thermogravimetric analysis conditions of biomass combustion.
