Abstract
Oxy-fuel combustion features an O2/CO2 atmosphere where O2 in the oxidant flow is diluted by CO2, rather than by N2 as in conventional air combustion. Because the chemical and thermal properties of CO2 are quite different from those of N2, the combustion characteristics and reaction pathways in oxy-fuel combustion will be influenced more significantly than its air-firing counterpart. In this chapter, using methane as the representative chemical compound, we review the effects of highly concentrated CO2 on reaction structures, reaction kinetics, ignition, pollution generation, and so on. The knowledge obtained reveals the fundamentals and special features of oxy-fuel combustion and functions as a foundation for deeper exploration of oxy-fuel combustion.
