Combustion regimes of magnesium in carbon oxides. 2. Combustion in CO

The oxidation and combustion of solitary magnesium particles in a CO medium in the range of ambient temperatures 898–1323 K are studied experimentally. Various regimes of interaction between magnesium and CO are revealed: low- and high-temperature regimes of slow heterogeneous combustion, low- and high-temperature regimes of vapor-phase combustion, and pulse combustion. The possible reasons for the existence of various regimes are discussed on the basis of an analysis of the processes in the surface film and in the gas phase with allowance for the thermodynamic features of the Mg–CO system.
