Combustion Regimes of Magnesium in Carbon Oxides.2.Combustion in CO

摘要

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:Iow- and high-temperature regimes of slow heterogeneous combustion,Iow- 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 pro-cesses in the surface film and in the gas phase with allowance for the thermodynamic features of the Mg-CO system.
